Hi Bill,

Attached are three shots of Philinopsis pilsbryi from the Marshall Ids, for comparison with the Philinopsis reticulata(?) sent earlier.

Dear Scott,
Thanks for the photos. I think they are all P pilsbryi. One major difference, is that the reticulate pattern does not continue under the body on to the sole of the foot in this species, as it does in P. reticulata. P. reticulata also has blue patches on the outside of the parapodial edge and on the inside of the parapodial edge at the anterior end.

Best wishes,
Bill Rudman.
