Chromodoris collingwoodi from Hong Kong

July 13, 2001
From: Bill Rudman & Brian Darvell

To accompany Leslie Chan's message, here is some information and photos on Chromodoris collingwoodi from Brian Darvell's Hong Kong collections. Hong Kong specimens appear to be characterized by the yellowish cream colour of the mantle with an irregular purplish border and a submarginal row of bright yellow spots. Inside the yellow spots are scattered, slightly raised brownish spots. Some of the more central brownish spots have clusters of small white specks. The rhinophore club is brown and the gills are edged with the same colour. In other parts of its range the brown spots are part of a much larger brown patch in the central part of the mantle. Grows to at least 40 mm long.
