kemarks.—In general appearance this species closely resembles 
the bright red form of Chiton vage but on eloser inspection 
the sculpture i is seen to be widely different. The ornamentation 
in some respects approximates to Callochiton platessa, but that 
species is much more strongly pitted or decussated, and the longi- 
tudinal scimitar- ‘shaped sulci are absent; also it is more strongly 
beaked than the species now described. Only one specimen has 
been obtained, and only the insertion plates of the first two 
valves have been examined.
