A single specimen is reported to have been obtained at the 

 above locality, which, as well as the following, may be erroneous. 

 C. lyrata, Ads. and Reeve (fig. 22), to which Mr. Arthur Adams 

 assigns the locality, China Sea, is evidently the same species. 



Unfigured and Unidentified Species of Cancellaria. 



C. TASMANICA, Tenison-Woods. Tasmania. 

 C. TRAILLI, Hutton. New Zealand. 

 C.MITROIDES, Fischer (Mus. Demidoff). Hab. unknown. 

 C. MULTIPLICATA, Lesson. Hab. unknown. 

 C. NASSA, Roissy. Hab. unknown. 

 C. ASPERULA, Desh. Hab. unknown. 

 C. DECUSSATA, Nyst. Hab. unknown. 

 This species is probably poorly figured ; it has been over- 

 looked by previous monographers. Possibly it equals C. 

 bifasciata, Desh.
