is a small cream species with fine papillae on its notum.

around its margin. The rhinophores are brown tipped with cream and the
branchia vary from green to brown (Note 1).

Observations and comments:
1: The branchia of an animal that
laid eggs in a dish changed from green
before laying to brown after laying. Over the following 3-4 days the
branchia changed back to green. Since the egg
masses of this species are greenish, perhaps the green pigment in the
branchia represents stored antifeedant chemicals (or their precursors)
that are deposited with the eggs, then regenerated?
