This genus or group, of whose exact position I am ignorant, re- 

 calls both Bucclwmi and Terehra ; it is seemingly closely related to, 

 if not identical with, Genea of Bellardi (3IolluscJu Terr-eni Terziari 

 del Piemonte, 1873, part 1, p. 205,)

Dr, Dall, in his report on the " Tertiary Mollusks of Florida" 

 (Trans. Wagner Free Inst. Science, III, 1890, pp, 134-35), refers 

 Buccitriton sagena, Conr, to Phos and B. altum, Conr. and B. Tex- 

 anum, Gabb, to Na.ssa. I see no good reason for generically sepa- 

 rating the species. The group appears to me to be neither Phos nor 

 Nassa.

I have seen no specimen answering to Gabb's figure or descrip- 

 tion ; the specimen marked in his hand-writing as the " type" of this 

 species is Natica minor, of Lea.
