narrow oblong spots; varices icw, rounded, with large chesnut 

 blotches; aperture rather expanded; outer lip reflexed, smooth, 

 with small linear chesnut spots at the edge ; columella covered 

 with a smooth polished transparent enamel; canal very short, 

 recurved. 



Hab. Hongkong. 



A single specimen of this very beautiful species was dredged 

 by William Cuthill, Esq., in the vicinity of Hongkong. A speci- 

 men of it in the old collection of the British Museum had been 

 inadvertently confounded with Triton Soiverbyi, (Reeve), from 

 which it is obviously distinct. The shell presents characters 

 common to several species but differs from all its congeners in the 

 form of tlie whorls being more rounded, and in the smoothness of 

 the mouth. Its nearest analogue is perhaps T. testaceus, { Morch ), 

 from which it differs in the last whorl being larger, the mouth 

 more open, and the spire more acute. It differs in the same 

 respects from T. ciat/iratus, (Sowerby), besides being much more 

 finely cancellated.

Hab. Hongkong {Cut/iill, two specimens). 



There is a specimen of this species also in the British Museum, 

 which was placed with O. adriaticuni, from w hich it differs consider- 

 ably in form and structure, being much stronger and more ventri- 

 cose.
