M. Kiener should have been sure of this shell being the Ranella 

 cattdata of Say, before he ventured to question the generic apjiropri- 

 ation of that species. It is quite another thing, and I much doubt 

 if a shell of sucli bright'and vivid colour were ever found within the 

 latitude of New York. The Ranella caudata belongs to a small group 

 of RaneUce, of which the R. Murici/ormis is tl)e type.

The Triton acuminatus is anotlier very aberrant form, though be- 

 longing to that interesting section of the genus of which the Triton 

 niveus is the type. 



Tritox gracilis. Trit. testd gracili-fusiformi, varicibus tribus ; 

 spird subelatd ; anfractibus tuberculato-nodosis , liris parvis subti-

A delicate little species, in which the outer lip is peculiarly fully 

 wrinkled within. 



Triton' elongatus. Trit. testd elongato-fusiformi, varice unico 

 subindistincto ; spird acuminata ; anfractibus superne leviter ungu- 

 latis, transversim liratis et striatis, liris striisque granuloso-

 elongato, subcontorto ; labro intus dentato, dentibus binis.

 This shell approximates very closely to the Triton vespaceus ; so 

 closely indeed, that I may be thought rather venturous to describe 

 it as a new species. The differences however are as follows : the 

 canal is much more elongated, the whorls are not tubercled, and the 

 beaded ridges are of a peculiar livid-purple colour. 



Triton gemmatus. Trit. testd elongato-oblongd, varicibus quatuor 



vel quinque ; spird subobtusd ; anfractibus liris, pulcherrime gem-
