 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.

This shell may have been probably confounded with the Triton 

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

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

 particulars.

 Conch. Icon., Triton, pi. 17. f. &9. 



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 sj)ecies, which j\I. Kiener thought to be 

 the recent analogue of Lamarck's fossil Triton viperinum. 



Triton verrucosus. Trit. testd subpyramidali- oblongd , varicibus
