PROSPECTUS DATED SEPTEMBER 16, 1996
 
- --------------------------------------------------------------------------------
 
Prudential  California  Municipal  Fund (the  "Fund")  (California  Series) (the
"Series") is one of three series of an open-end, management investment  company,
or  mutual fund.  This Series  is diversified and  seeks to  provide the maximum
amount of income that is exempt  from California State and federal income  taxes
consistent  with the preservation of capital  and, in conjunction therewith, the
Series may invest in  debt securities with the  potential for capital gain.  The
net  assets of the  Series are invested  in obligations within  the four highest
ratings of either Moody's Investors Service  or Standard & Poor's Ratings  Group
or  in  unrated  obligations which,  in  the  opinion of  the  Fund's investment
adviser, are of comparable quality. Subject to the limitations described herein,
the Series  may  utilize  derivatives,  including  buying  and  selling  futures
contracts  and  options  thereon  for  the  purpose  of  hedging  its  portfolio
securities. There can be no assurance that the Series' investment objective will
be achieved. See "How the Fund Invests--Investment Objective and Policies."  The
Fund's address is One Seaport Plaza, New York, New York 10292, and its telephone
number is (800) 225-1852.

  of each time period:.......................................  $     7      $    21      $     37      $     83
The  above example is  based on expenses expected  to have been incurred  if Class Z shares  had been in existence
throughout the fiscal year ended August 31, 1995. THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR
FUTURE EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
The purpose of this table is to assist investors in understanding the various costs and expenses that an  investor
in  Class  Z  shares of  the  California Series  will  bear, whether  directly  or indirectly.  For  more complete
descriptions of the various costs and expenses, see "How the Fund is Managed." "Other Expenses" includes operating
expenses of the Series, such  as Trustees' and professional fees,  registration fees, reports to shareholders  and
transfer agency and custodian fees.

 *Estimated  based on expenses expected to have  been incurred if Class Z shares
  had been  in existence  throughout  the fiscal  year  ended August  31,  1995,
  without taking into account the management fee waiver. At the current level of
  management  fee waiver  (.05%), Management Fees  would be .45%  and Total Fund
  Operating Expenses would be .62% of average net assets of the Series' Class  Z
  shares.

  THE  FOLLOWING INFORMATION SUPPLEMENTS "HOW  THE FUND IS MANAGED--DISTRIBUTOR"
IN THE RETAIL CLASS PROSPECTUS:
 
  Prudential Securities  Incorporated  (Prudential  Securities)  serves  as  the
Distributor  of  Class Z  shares  and incurs  the  expenses of  distributing the
Series' Class Z  shares under a  Distribution Agreement with  the Fund, none  of
which is reimbursed by or paid for by the Series.
 
  THE FOLLOWING INFORMATION SUPPLEMENTS "TAXES, DIVIDENDS AND
DISTRIBUTIONS--TAXATION OF SHAREHOLDERS" IN THE RETAIL CLASS PROSPECTUS:
 
  The  Fund has obtained opinions of counsel  to the effect that neither (i) the
conversion of Class B shares  into Class A shares nor  (ii) the exchange of  any
class  of the  Series' shares for  any other  class of its  shares constitutes a
taxable event for federal  income tax purposes. However,  such opinions are  not
binding on the Internal Revenue Service.
 
  THE  FOLLOWING  INFORMATION  SUPPLEMENTS  THE  INFORMATION  UNDER "SHAREHOLDER
GUIDE--HOW TO BUY SHARES OF THE  FUND" AND "SHAREHOLDER GUIDE--HOW TO SELL  YOUR
SHARES" IN THE RETAIL CLASS PROSPECTUS:
 
  Class Z shares of the Series are available for purchase by participants in any
fee-based  program sponsored  by Prudential  Securities or  its affiliates which
includes mutual  funds as  investment options  and for  which the  Series is  an
available option.
 
  In connection with the sale of Class Z shares, the Manager, the Distributor or
one  of their affiliates  may pay dealers, financial  advisers and other persons
which distribute shares a finders'  fee based on a  percentage of the net  asset
value of shares sold by such persons.
 
  THE FOLLOWING INFORMATION SUPPLEMENTS "SHAREHOLDER GUIDE--HOW TO EXCHANGE YOUR
SHARES" IN THE RETAIL CLASS PROSPECTUS:
 
  Class Z shareholders of the Series may exchange their Class Z shares for Class
Z  shares of  another Series or  other Prudential  Mutual Funds on  the basis of
relative net asset value.  Shareholders who qualify to  purchase Class Z  shares
(other  than participants in any fee-based program)  will have their Class B and
Class C shares which  are not subject to  contingent deferred sales charges  and
their  Class  A  shares exchanged  for  Class  Z shares  on  a  quarterly basis.
Participants in  any fee-based  program for  which the  Series is  an  available
option will have their Class A shares, if any, exchanged for Class Z shares when
they  elect to have  those assets become  a part of  the fee-based program. Upon
leaving the program (whether voluntarily or  not), such Class Z shares (and,  to
the  extent  provided  for  in  the program,  Class  Z  shares  acquired through
participation in the program) will be exchanged for Class A shares at net  asset
value.  See "Shareholder  Guide--How to  Exchange Your  Shares--Special Exchange
Privilege."
 
  THE INFORMATION ABOVE ALSO SUPPLEMENTS THE INFORMATION UNDER "FUND HIGHLIGHTS"
IN THE RETAIL CLASS PROSPECTUS AS APPROPRIATE.

                              (CALIFORNIA SERIES)
                     Supplement dated September 16, 1996 to
                       Prospectus dated November 1, 1995
- --------------------------------------------------------------------------------
 
  THE  FOLLOWING  INFORMATION SUPPLEMENTS  "GENERAL  INFORMATION--DESCRIPTION OF
SHARES" IN THE PROSPECTUS:
 
  The Series is authorized to offer an unlimited number of shares of  beneficial
interest,  divided into  four classes  of shares,  designated Class  A, Class B,
Class C and Class Z shares. Each class represents an interest in the same assets
of the Series and  is identical in  all respects except that  (i) each class  is
subject  to different sales charges and distribution and/or service fees (except
for Class Z shares which are not  subject to any sales charges and  distribution
and/or  service  fees),  which  may  affect  performance,  (ii)  each  class has
exclusive voting rights  on any  matter submitted to  shareholders that  relates
solely to its arrangement and has separate voting rights on any matter submitted
to shareholders in which the interests of one class differ from the interests of
any  other class, (iii) each class has a different exchange privilege, (iv) only
Class B shares  have a conversion  feature and  (v) Class Z  shares are  offered
exclusively for sale to a limited group of investors. For more information about
Class  Z shares, contact your Prudential  Securities financial adviser or Prusec
representative or telephone the Fund at (800) 225-1852. Participants in programs
sponsored  by  Prudential  Retirement  Services  should  contact  their   client
representative  for more  information about  Class Z  shares. Since  Class B and
Class C shares generally bear higher distribution expenses than Class A  shares,
the liquidation proceeds to shareholders of those classes are likely to be lower
than  to Class A shareholders and to  Class Z shareholders, whose shares are not
subject to any distribution  and/or service fee. In  accordance with the  Fund's
Declaration  of  Trust, the  Board  of Trustees  may  authorize the  creation of
additional  series  and  classes  of  shares  within  such  series,  with   such
preferences, privileges, limitations and voting and dividend rights as the Board
of  Trustees  may  determine. Currently,  the  Series is  offering  four classes
designated Class A, Class B, Class C and Class Z shares.
 
  THE FOLLOWING INFORMATION SUPPLEMENTS "HOW THE FUND CALCULATES PERFORMANCE" IN
THE PROSPECTUS:
 
  The Fund may  include comparative  performance information  in advertising  or
marketing the Series' shares. The Fund may include performance information about
each  of the Series'  classes and is  no longer required  to include performance
data for  all  classes of  shares  in  any advertisement  or  other  information
including  performance  data  of  the  Series.  See  "How  the  Fund  Calculates
Performance."

Prudential  California Municipal  Fund (the  "Fund") (California  Income Series)
(the "Series") is  one of  three series  of an  open-end, management  investment
company,  or mutual fund.  This Series is  diversified and seeks  to provide the
maximum amount of income that is exempt from California State and federal income
taxes consistent  with  the preservation  of  capital. The  Series  will  invest
primarily  in  investment  grade municipal  obligations  but may  also  invest a
portion of its  assets in  lower-quality municipal obligations  or in  non-rated
securities  which,  in the  opinion  of the  Fund's  investment adviser,  are of
comparable quality.  Subject to  limitations described  herein, the  Series  may
utilize  derivatives, including buying and selling futures contracts and options
thereon for the  purpose of hedging  its portfolio securities.  There can be  no
assurance  that the Series' investment objective  will be achieved. See "How the
Fund Invests--Investment  Objective and  Policies." The  Fund's address  is  One
Seaport  Plaza, New  York, New  York 10292,  and its  telephone number  is (800)

 The  above example is based  on expenses expected to have  been incurred if Class Z  shares had been in existence
 throughout the fiscal year ended August 31, 1995. THE  EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF  PAST
 OR FUTURE EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
 The purpose of this table is to assist investors in understanding the various costs and expenses that an investor
 in  Class Z shares of the  California Income Series will bear, whether  directly or indirectly. For more complete
 descriptions of  the various  costs  and expenses,  see "How  the  Fund is  Managed." "Other  Expenses"  includes
 operating  expenses  of the  Series,  such as  Trustees'  and professional  fees,  registration fees,  reports to
 shareholders and transfer agency and custodian fees.

 *Estimated based on expenses expected to  have been incurred if Class Z  shares
  had  been  in existence  throughout  the fiscal  year  ended August  31, 1995,
  without taking into account the management fee waiver. At the current level of
  management fee waiver (.425%), Management Fees  would be .075% and Total  Fund
  Operating Expenses would be .285% of average net assets of the Series' Class Z
  shares.

    The Fund has obtained opinions of counsel to the effect that neither (i) the
conversion  of Class B shares  into Class A shares nor  (ii) the exchange of any
class of the  Series' shares for  any other  class of its  shares constitutes  a
taxable  event for federal  income tax purposes. However,  such opinions are not
binding on the Internal Revenue Service.
 
    THE FOLLOWING  INFORMATION SUPPLEMENTS  THE INFORMATION  UNDER  "SHAREHOLDER
GUIDE--HOW  TO BUY SHARES OF THE FUND"  AND "SHAREHOLDER GUIDE--HOW TO SELL YOUR
SHARES" IN THE RETAIL CLASS PROSPECTUS:
 
    Class Z shares of the Series  are available for purchase by participants  in
any fee-based program sponsored by Prudential Securities or its affiliates which
includes  mutual funds  as investment  options and  for which  the Series  is an
available option.
 
    In connection with the sale of Class Z shares, the Manager, the  Distributor
or one of their affiliates may pay dealers, financial advisers and other persons
which  distribute shares a finders'  fee based on a  percentage of the net asset
value of shares sold by such persons.
 
    THE FOLLOWING INFORMATION  SUPPLEMENTS "SHAREHOLDER  GUIDE--HOW TO  EXCHANGE
YOUR SHARES" IN THE RETAIL CLASS PROSPECTUS:
 
    Class  Z shareholders of  the Series may  exchange their Class  Z shares for
Class Z shares of another Series or  other Prudential Mutual Funds on the  basis
of relative net asset value. Shareholders who qualify to purchase Class Z shares
(other  than participants in any fee-based program)  will have their Class B and
Class C shares which  are not subject to  contingent deferred sales charges  and
their  Class  A  shares exchanged  for  Class  Z shares  on  a  quarterly basis.
Participants in  any fee-based  program for  which the  Series is  an  available
option will have their Class A shares, if any, exchanged for Class Z shares when
they  elect to have  those assets become  a part of  the fee-based program. Upon
leaving the program (whether voluntarily or  not), such Class Z shares (and,  to
the  extent  provided  for  in  the program,  Class  Z  shares  acquired through
participation in the program) will be exchanged for Class A shares at net  asset
value.  See "Shareholder  Guide--How to  Exchange Your  Shares--Special Exchange
Privilege."

                      PRUDENTIAL CALIFORNIA MUNICIPAL FUND
                           (CALIFORNIA INCOME SERIES)
                     Supplement dated September 16, 1996 to
                       Prospectus dated November 1, 1995
- --------------------------------------------------------------------------------
  THE  FOLLOWING  INFORMATION SUPPLEMENTS  "GENERAL  INFORMATION--DESCRIPTION OF
SHARES" IN THE PROSPECTUS:
  The Series is authorized to offer an unlimited number of shares of  beneficial
interest,  divided into  four classes  of shares,  designated Class  A, Class B,
Class C and Class Z shares. Each class represents an interest in the same assets
of the Series and  is identical in  all respects except that  (i) each class  is
subject  to different sales charges and distribution and/or service fees (except
for Class Z shares which are not  subject to any sales charges and  distribution
and/or  service  fees),  which  may  affect  performance,  (ii)  each  class has
exclusive voting rights  on any  matter submitted to  shareholders that  relates
solely to its arrangement and has separate voting rights on any matter submitted
to shareholders in which the interests of one class differ from the interests of
any  other class, (iii) each class has a different exchange privilege, (iv) only
Class B shares  have a conversion  feature and  (v) Class Z  shares are  offered
exclusively for sale to a limited group of investors. For more information about
Class  Z shares, contact your Prudential  Securities financial adviser or Prusec
representative or telephone the Fund at (800) 225-1852. Participants in programs
sponsored  by  Prudential  Retirement  Services  should  contact  their   client
representative  for more  information about  Class Z  shares. Since  Class B and
Class C shares generally bear higher distribution expenses than Class A  shares,
the liquidation proceeds to shareholders of those classes are likely to be lower
than  to Class A shareholders and to  Class Z shareholders, whose shares are not
subject to any distribution  and/or service fee. In  accordance with the  Fund's
Declaration  of  Trust, the  Board  of Trustees  may  authorize the  creation of
additional  series  and  classes  of  shares  within  such  series,  with   such
preferences, privileges, limitations and voting and dividend rights as the Board
of  Trustees  may  determine. Currently,  the  Series is  offering  four classes
designated Class A, Class B, Class C and Class Z shares.

  The Fund may  include comparative  performance information  in advertising  or
marketing the Series' shares. The Fund may include performance information about
each  of the Series'  classes and is  no longer required  to include performance
