Supplement dated November 22, 1996 to Prospectus dated February 18, 1996
Effective November 22, 1996, Janus Money Market Fund, Janus Government Money
Market Fund and Janus Tax-Exempt Money Market Fund will offer three classes of
shares. This prospectus describes "Institutional Shares," which are available
only to institutional investors that meet the $250,000 minimum. "Investor
Shares" are described in a separate prospectus and are available to the general
public. "Service Shares" are described in a separate prospectus and are offered
exclusively through banks and other financial institutions that meet minimum
investment requirements in connection with trust accounts, cash management
programs and similar programs provided to their customers. Because the expenses
of each class may differ, the performance of each class is expected to differ.
