Bill,
We think that Atsushi's white shelled form is the same as our white 'miniham'. I have attached two scans of an animal from Yap that shows some of the modification of the head shield. Our first mnemonic for this animal was 'poodle head'. We have one specimen from Guam that has no brown lines. The Kerama specimen seems to show a hint of the short brown
lines ala the form from Yap. The external morphology of the white form appears identical to our most common miniham. The tail is relatively short, there are projections on the posterior pallial lobe and the lobes on the head shield extend at right angles from the head. I have attached a photo of a gizzard plate of the common mini24. If the white form is the same, the radula will be 2.1.2 with a broad, smooth, concave bladed rachidian. The two laterals will have denticulate outer edges. [you already have a scan of the shell of C.24 [=mini24]].
• mini91a, mini91b 3mm; Yap, Miil channel, 13m; 4 January 1994
• mini24_5 gizzard plate, 2.5mm specimen; Guam, Bile Bay, 4m; 19 April 1988.

Dear Clay & Patty Jo,
These are interesting little animals. In both of your photos the small papillae radiating out from the flap of skin covering the rear end of the shell (posterior pallial lobe) are very noticeable.
Best wishes,
Bill Rudman.
