Vinceyitinus) can readily be distinguished by the greater length 

 and proportionate narrowness of the aperture. 



B. multifasciatus occurs in Martinique, and also in St. Kitts. 

 Mr. Rawson, Governor of the Bahamas, recently sent to me two 

 specimens attributed to Crooked Island, and among shells col- 

 lected by the late Dr. Bryant at Inagua, I found one broken 

 example. In St. Kitts there is a yellow variety, with scarcely a 

 perceptible trace of bands. The species is also found in South 

 America. Reeve's figure (Conch. Icon., pi. xlvi, No. 295) of 

 this species is a good one of the typical (banded) form.

Guppy (Ann. and Mag., Jan'y, 1866) thus described this as 

 B. multifasciatus^ Lam., var. imperfectus : — 



Shell subperforate, oblong conic, thin, fragile, subpellucid, 

 shining, striated by fine longitudinal lines of growth, and zoned 

 with five chestnut bands, of which the fourth is the broadest, 

 and the second the smallest ; whorls b-Q^ scarcely convex ; per- 

 istome simple, acute. Height, 0*6 inch; breadth, 0-3 inch ; height 

 of aperture, 0.25 inch. 



He remarks, " this variety is much like the young of the ty- 

 pical form. Its peristome is more complete than in the young 

 shell of the type, but never expanded as in the adult. In the 

 Southern parts of the island, where this yariety occurs, I have 

 never met with a single example of the type form." Guppy, in 

 using the expressions " typical form " and " type," refers to the 

 species which I consider to be B. Vincentinus, Pfr. 



This shell, with nearly six whorls, and little more than half 

 the size of B. multifasciatus ^ Lam., can scarcely be considered 

 as a variety of that species. It is totally distinct from H. Vin- 

 cent inus. 



In general form it is like, but less ventricose than B. nigri- 

 UneatuSy Reeve, (Conch. Icon. No. 567), of which no habitat is 

 given. 



22. BuLiMUS AUREOLUS, Guppy. Ann. and Mag., Jan'y, 1866. 



A rare species, of which a few examples had been found on 

 trees at Savana Grande only. Guppy. 

 I have not seen any specimen of this shell. 



23. BuLiMUS TENUTSSIMUS, Ferussac. 



Found amongst decaying wood and leaves. Gill, Guppy. 

 Occurs also in South America. 



Guppy (Ann. and Mag., 1. c.) refers this, as I did in my Cat- 

 alogue, (Ann. Lye, vii, 1861), to B. fraterculus, Fer. Speci-
