Picton, 1980

Description:
The adults may reach 50 mm in length; the body is pellucid white, with opaque white lobes of the ovotestis visible through the skin. Superficial chalk-white pigment forms a dorsal streak from the rearmost cerata to the metapodial tip. Both the wrinkled rhinophores and the elongated oral tentacles are streaked with white (lacking the pinkish tinge found in true Coryphella verrucosa ). There are up to eight clusters of cerata on either side of the back, and these clusters comprise up to 15 rows of cerata, each row having up to five individual cerata. Each ceras has a sub-terminal broad white band and the digestive gland within varies in colour from bright red to dark brown.

Habitat:
This beautiful species forms dense populations, sometimes mixed with Coryphella lineata , feeding on the hydroid Tubularia indivisa .

Distribution:
It ranges southwards along the French coast to Brittany, but there are only scarce records from the North Sea (Distr. C. browni).
