Spurilla sp. 2

Brownish background colour with whitish spots. Rhinophores lamellate, not papillate.
I suspect some of the white spotted animals from the Caribbean which have been tentatively identified on the Forum as Spurilla neapolitana [see messages from Colombia - message 1, message 2] may be Spurilla creutzbergi but I can't see enough detail in their rhinophores. Some, such as David Behrens animal from Belize, cannot be this species because the rhinophores are clearly ridged transversely.
Clearly this is another Caribbean group that could do with some anatomical work.
