Dear Bill and Kathe,
Following our earlier conversation I fortunately found at third specimen of Sohgenia palauensis [LOWER PHOTO] and Cyerce kikutarobabai [UPPER PHOTO].
I live in an isolated island, it took long to develop films. I don't know "transverse groove" so I tried to take photos of foot.
Can you see it in my photo of C. kikutarobabai?

Thanks very much for these two photos which show the difference very well. In the upper photo we can see a roundish anterior disc and then an elongate tapering section of the foot. The 'groove' separating the two parts of the foot is in line with the front pair of the large dorsal cerata. In the lower photo, of Sohgenia there is no sign of the groove. Another feature which can be clearly compared is the presence of oral tentacles in Cyerce and their absence in Sohgenia. Although it looks like their are two pairs of head tentacles in Sohgenia, what we can see is one pair of rhinophores which bifurcate into two arms right near the base.
