Re: Bob Bolland's unknown 'bornellids'

Bob,
A day after I posted your messages ['Bornella? from Okinawa', and 'Pseudobornella? from Okinawa'] I've just noticed Baba's description of Dendronotus gracilis Baba, 1949 which was based on a single specimen approximately 25mm long. Without going into details, it seems almost identical in shape and colour to your white species. However, just to make life difficult, Baba's species has scattered yellow spots, which from the painting in Opisthobranchia from Sagami Bay look, in size and distribution, very like those on your [second species.

I suspect there is nothing much we can say until the anatomy of your two 'species' is studied and more specimens are found to see just how much variability there is bot in colour and external shape.
Cheers,
Bill Rudman
