 „ bicolor, Angas, South Austral. Moll., Proc. Zool. Soc. Lond., 1865, p. 170, No. 92.1 



Station 186. September 8, 1874. Lat. 10° 30' S., long. 142° 18' E. Wednesday 

 Island, Cape York. 8 fathoms. Coral mud. 



Habitat.— Australia, New Holland, Tasmania, Sandwich Islands (British Museum) ; 

 Port Adelaide Creek, South Australia (Angas). 



The Challenger shell is a very young specimen belonging probably to this species. 



Whether the distinction between Cyprcea bicolor and Cyprcea piperata, Gray, will stand seems 

 doubtful. At the same time I must remark that the presence of three broad coloured bands in 

 Gaskoin's species, instead of four narrow ones, as in Gray's, is a feature of difference which, however 

 unlikely to be permanent, does yet in fact seem to be so.
