Gray, Griffith's Cuvier's Animal Kingdom. 



Hab. Island of Luzon, Philippines ; Cuming. 



This species, which approximates to the Triton acumi- 



natus, may be recognised by the peculiar expansion of 



the outer lip. 



Species 97. (Mus. Norris.)

 acuminato-turrild, varice nulla ; anfractibus subvert- 

 tricosis, superne angulatis, transversim creberrime

 prcssiusculis, siihilislantihus ; ulbiild, rubii/o-cas/aneo 

 multifasciatd ; canali brevi, vald't recurvo ; aperturd 

 rotunda ; labro intus elevato-striato. 



The pagoda Triton. Shell pyramidally ovate ; spire 

 acuminately turreted, no varix ; whorls rather ven-

Reeve, Pro. Zool. Soc, 1*44. 



Hab. Bay of Montija, West Columbia ; Cuming. 



This species partakes more of the character of Nassa 



than the preceding ; it might be referred indeed to that 



genus with almost as much propriety as to Triton.

 cinered ; aperturd contractu, fauce Imvigatd.

A small species, in which the ribs are numerous, close-

 Triton fictilis. Trit. testd ovatd, solidu/d, varicibus 



Species 99. (Mus. Cuming.) 



Triton pictus. Trit. testd oblongo-ovatd ; spird sub-

Hab. Gallapagos Islands (found under stones at low

 ponderates.

Triton anomalus. Trit. testa ovatd, varice mild ; spira 

 siihuhtusd ; an/'raiiiliiis longitudinaliter costatis. linris 

 elevatis transversis cancellatis ; suturis subprofundis .

 turd ovatd.
