Roughly granulcd throughout, and obscurely encircled

 margins joined, upper margin furnished with a thick 

 oblong tooth, lower with two thin internal teeth.

Ilai. Martinique. 



Very closely allied to //. pnrbgganlra, from which it 

 differs in having so prominent an oblong callous tooth.

This beautifully sculptured shell, the Jlelijr delphinula, 

 Lowe, from .Madeira, is included by Dr. Pfcilfer in his list 

 of fossil species.
