Re: unidentified cephalaspid from Kerama Is

Atsushi must be getting into the Lyngbya.  We find both the earlier Ventomnestia villica and this unknown species in that type of environment.  We doubt if this animal or a second very similar form have been described.  The shells are extremely fragile.  They are easily broken with a fine jet of water from a syringe.  We have not done any dissecting on this particular form, but do have the attached shell as well as data on the egg mass and
development times. 

We have three gross classifications:  atyid, haminoeid, otherid   -- this present animal is in our 'otherid' class.

Shell, 2.5 x 1.9mm;  Guam, Bile Bay, 17m;  1 July 1998. [c132_2a C.132]

Dear Clay & Patty Jo,
I am sure this is not the only 'otherid' you have. Thanks for letting us know.
