Re: Massachusetts Mutual Life Insurance Company
MML Series Investment Fund
File No. 2-39334
- -------------------------------------------------
Dear Commissioners:
On behalf of Massachusetts Mutual Life Insurance Company (the "Company")
and MML Series Investment Fund (the "Fund"), we are filing a certification
pursuant to paragraph (j) of Rule 497 under the Securities Act of 1933. In
this regard, we certify that the form of prospectus and Statement of Additional
Information ("SAI") for this no-load, open-end, diversified management
investment company otherwise required to be filed under paragraph (c) of
Rule 497 would not have differed from the form of prospectus and SAI contained
in post-effective amendment number 34 to the Form N-1A registration statement
for the Fund that was filed electronically with the Securities and Exchange
Commission on April 26, 1996 via EDGARLINK.
Sincerely,
/s/ James M. Rodolakis
