 nearly resembles in general appearance by its peculiarly flattened 

 ridges.

 the Mitra cucumerina.

 Mitra crenulata (pars), Kiener, Icon., f. 105 a. 

 Hab. Coast of China. 



TL^is fine species, though one of great rarity, has been probably 

 confounded hitherto 'with the Mitra crenulata, an error into which I 

 had myself fallen, until the arrival of a magnificent specimen most 

 liberally forwarded to me for inspection by M. Gruner of Bremen, 

 and which has been invaluable as the means of establishing a new 

 and very important species. It difFers entirely from the Mitra crenu- 

 lata, independent of coloiu-ing and size, in the character of its sculp- 

 ture, whilst the columella has an additional number of plaits and is 

 armed with a remarkable callosity at the summit.
