MOLLUSCA. 11 



Inhab. Cape Blanco, west coast of Africa. 



A specimen of Murex Cleryi from Paris has enabled me to compare it with 

 Typhis Selcheri, and to coincide in the opinion, previously gathered from the 

 descriptions and figures, that they are the same species. 



Triton . Montfort. 



22. Triton vestitus, Hinds, Proceed. Zool. Soc. Feb. 27, 1844. (Plate IV. fig. 1, 2.) Testa 

 ovata, solida, fusca ; anfractibus rotundatis, transversim striatis, lineis longitudinalibus decussantibus 

 prsecipue spires, nodulosis, ultimo albo fasciato ; apertura elongate ovali ; labro incrassato ; intus

Inhab. Realejo, Gulf of Nicoya, and Bay of Honda, on the west coast of 

 America, among the rocks of the shore. 



23. Triton convolutus, Broderip, Proceed. Zool. Soc. 1833, p. 7. 



Inhab. Marquesas, in from seven to ten fathoms, sandy mud. New Guinea, 

 in twenty-two fathoms, among soft mud. 



I am happy to be enabled to rescue this species from the oblivion into which 

 it was fast gliding. It is not uncommon in collections, where it seems to be re- 

 garded as hitherto undescribed. When it came under my notice, I felt much 

 doubt on the subject, and Mr. Broderip has favoured me with his opinion that it 

 is properly referred as above. 



24. Triton bracteatus, Hinds, 1. c. (Plate IV. fig. 5, 6.) Testa ovata, elongata, longitrorsum 

 costata, transversim striata, maculis parvis nigris seriatim dispositis ornata ; spira aperturam supe- 

 rante; apertura parva, alba, denticulata; canali breviusculo. 



Inhab. Marquesas, in from seven to ten fathoms, among sandy mud. New 

 Ireland, among the coarse sand of the beach. Straits of Malacca, in seventeen 

 fathoms, mud. 



The numerous little black spots with which the surface of this shell is 

 ornamented, are disposed in a very regular manner, and longitudinally obey the 

 direction of the ribs, and transversely present an interrupted fasciation. 



25. Triton truncatus, Hinds, 1. c. (Plate IV. fig. 9, 10.) Testa solida, fulva, fusco nebulosa, 

 truncata, longitrorsum costata, striis decussantibus ; costis rotundatis confertis ; anfractu ultimo 

 pallide fasciato ; apertura alba, denticulata ; canali breviusculo. 



Inhab. New Ireland. In society with T. bracteatus. 



The three specimens alone collected are truncated in an uniform and appa-
