A delicate little species, in ■n'hich the outer lip is peculiarly fully 

 wrinkled within.

This shell approxiniates 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 foUoAvs : 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 guatuor- 

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

 matis, cingulatis, interstitiis striis elevatis lo7igitudinalibus et trans- 

 versis eximie clathratis ; aurantio-lutescente ; columelld rugosd, 

 callositate superne arniatd ; canali breviusculo ; labro intus dentato, 

 dentibus binis.

Var. /3. Testd albd, varicibus duobus ad sex ; liris subnodosis. 

 Hab. Island of Annaa (Chain island), South Pacific Ocean, and 

 island of Buriąs, Philippines (found under stones in both localities at 

 low \vater) ; Cuming. 



The sculpture of this shell is very similar to that of the Triton 

 rubecula ; the beaded ridges are however wider apart, and on the 

 varices have three smaller ridges between them. 



Triton obscurus. Trit. testd elongato-turritd, varicibus unde- 

 cim ; spird acuminatd ; anfractibus transversim granulosis, longi- 

 tudinaliter subobsolete sitlcatis, suleis creberrimis ; fuscescente, 

 fusco pallide balteatd, maculis fuscis guadratis perpaucis seriatim 

 pictd, varicibus fusco maculatis ; columelld Itevi, crassissime en- 

 causticd ; canali brevissimo, labro intus denticulato.
