Hab. North coast of New Guinea ; from seven fathoms, among 

 mud. 



The whorls are closely set with ribs, in numbers almost too great 

 to be enumerated.

Hab. Island of Quibo, Veragua, Central America ; from thirty 

 fathoms, among mud ; the temperature below being 58°, and at the 

 surface 82°. 



A pretty little shell, which, under first impressions, the propriety 

 of placing in Scalaria might be called in question, though it pos- 

 sesses the characters assigned to the genus. Still there is a differ- 

 ence of character and appearance, which creates a momentary hesi- 

 tation. But, together with its deep suture, the basal whorl is pro- 

 vided at its inferior surface with a blunt keel, which is also to be 

 met with in a few other species of Scalaria, but I am not aware in 

 any other genus, and which induces me to place it here without the 

 least doubt as to the propriety of its location. 



The following new species of Murex were collected, with three 

 exceptions, during the voyage of the Sulphur, under the command 

 of Sir Edward Belcher, C.B., and figures of them will shortly be 

 published in the ' Zoology' of the Voyage. These descriptions are by 

 Mr. Hinds.

This shell is another of those typical forms of Murex which have 

 recently become somewhat numerous, and which appear to be con- 

 fined to the tropical seas. I am strongly disposed to think that it is
