 enumerated.

Inhab. 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 possesses the characters as- 

 signed to the genus. Still there is a difference of character and appearance 

 which creates a momentary hesitation. But, together with its deep suture, the 

 basal whorl is provided 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.
