Re:  Hartford Series Funds, Inc. (SEC File Nos. 33-45431 and 811-08629)
     Preliminary Proxy Statement with respect to Hartford Small Company HLS Fund

Dear Mr. Kosoff:

This letter responds to comments you provided to Gerardo Perez-Giusti and me in
a telephonic discussion on March 21, 2006, regarding the Preliminary Proxy
Statement ("Proxy") for Hartford Small Company HLS Fund (the "Fund"), a series
of Hartford Series Funds, Inc. (the "Registrant"), filed with the Securities and
Exchange Commission (the "Commission") on March 10, 2006. A summary of your
comments and the Registrant's responses thereto are provided below.


          COMMENT 1: Please clarify whether fractional shares will have voting
          rights.

          RESPONSE:  We will incorporate language to clarify that each full
          share outstanding is entitled to one vote, and each fractional share
          outstanding is entitled to a proportionate share of one vote.

          COMMENT 2: Please move the Board of Directors' Considerations
          discussion from Appendix D to the main body of the Proxy.

          RESPONSE:  We will incorporate your comment.

          COMMENT 3: Please clarify in the Proxy whether Hartford Investment
          Management's allocation will initially be limited to new inflows of
          assets into the Fund, and whether this allocation may be increased by
          the Board or the Investment Manager in the future.

          RESPONSE:  We will incorporate your comment.

          COMMENT 4: If applicable, please provide appropriate disclosure about
          other funds advised by Hartford Investment Management that have a
          similar investment objective to that of the Fund (reference Item
          22(c)(10) of Schedule 14A).

          RESPONSE:  Not applicable.  Hartford Investment Management does not
          currently provide advisory services to any other fund with an
          investment objective similar to that of the Fund.

Please feel free to call me at 212.698.3806, or John V. O'Hanlon at

Very truly yours,
