Hab. Corsica. 
This species is indeed very nearly allied to Mel. equalis. Yet in this 
last there is not the slightest trace of “ transverse’? (sc. spiral) striz, 
the whole shell being quite smooth and glossy. It also differs remarkably 
in colour, and isa less slender and proportionally shorter, and more ventri- 
cose shell. But ina 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 Bruguiére, says generally of his ‘‘ Melampes,’’ 
(including in the genus Bulimus coniformis, monilis and ovulus, Brug.) 
« Elles habitent les rivitres des Antilles.’’ I have very little doubt the 
present species is truly, like the rest, marine, though possibly found at 
the mouths of rivers.
