Hab. Corsica. 



This species is indeed very nearly allied to Mel. cequalis. Yet in this 

 last there is not the slightest trace of " transverse" (sc. spiral) striae, 

 the whole shell being quite smooth and glossy. It also differs remarkably 

 in colour, and is a less slender and proportionally shorter, and more ventri- 

 cose shell. But in a case of this sort it is hardly possible to decide with- 

 out a comparison of specimens ; and though at present, from the descrip- 

 tions, the two appear perfectly distinct, it is possible that such a compa- 

 rison may hereafter prove their identity.

 Cuvier, probably after Bruguiere, says generally of his " Melampes,''^ 

 (including in the genus Bulimus canifarmis, monilis and ovulus^ Brug.) 

 " Elles habitent les rivieres des Antilles." I have very httle doubt the 

 present species is truly, like the rest, marine, though possibly found at 

 the mouths of rivers.
