Shell oval, inflated, thin, ivory-white, smooth; volutions six, 

 tumid : outer lip thin and smooth. 



Length an inch and three-quarters; breadth rather more than 

 an inch. 



This very'curions shell, a duplicate of which we have never 

 seen, was dredged up off Plymouth. It very much resembles the 

 Buccinum novum Groenlandlciim of Chemnitz, x. p. 182. tab. 152. 

 f. 1448.; but that shell is represented as of a blueish colour, and 

 marked with remote transverse stria; : the volutions also of Chem- 

 nitz's shell appear to be not so much raised.

Test& subglobosa, obtusissima, Icevi ; anfractibus tribus, vix pro- 

 duetts; castanea,fasciis obscuris pallidis ; columella etfauce 

 castanets. 



Shell subglobular, very obtuse, smooth, with three hardly pro- 

 duced volutions ; of a chesnut colour, with obscure pale bands : 

 pillar and throat chesnut. 



Diameter about a line. 



Found on the rocks at Scarborough, by Mr. Bean. It is often 

 covered with a gray coat which hides its colours and marks : the 

 bands are about twelve in number, apparently interrupted, so as to 

 give the surface a chequered appearance ; and under a very good 

 glass it seems very finely striate circularly. It is twice the size of 

 T.fulgidus, and more obtuse than any of its genus.
