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

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

 low water) ; 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 sulcatis, sulcis creberrimis ; fuscescente,

 Conch. Icon., Triton, pi. 16. f. 63. 

 Hab. East. Indies ; Lieut. Babb. 



This shell may have been probably confounded with the Triton 

 maculosus ; it differs however in not being transversely grooved, in 

 having a different arrangement of the varices, and in other minor 

 particulars. 



Triton crispus, Trit. testd ovatd, subfusiformi, varicibus duobus 

 vel tribus ; spird breviusculd ; anfractibus liris crispis prominen-

 Conch. Icon., Triton, pi. 17. f. 69. 



Hab. Island of Ticao, Philippines (found under stones at low 

 water) ; Cuming. 



This shell has somewhat the form of the Triton Quoyi, an inter- 

 esting little New Holland species, which M. Kiener thought to be 

 the recent analogue of Lamarck's fossil Triton viperinum. 



Triton verrucosus. Trit. testd subpyramidali-oblongd, varicibus 

 quatuor vel quinque ; spird mediocri ; anfractibus superne impressis, 

 transversim striatis et liratis, liris longitudinalibus prominentioi'i-
