NOTES. 



1. Antigua. — The species which have come under my notice from this island, 

 and St. Christopher, were collected by the Rev. A. Hamilton. 



2. Bahamas. — The New Providence shells were collected by Mr. "Wm. Cooper, 

 and Mr. T. Smitten, — those from Turk's Island by Mr. Theo. Gill and others. 



3. Barbados. — For tliese shells I am indebted to the late Rev. J. Parkinson, Mr. 

 Gill, <fec. B. ohlongus Miill. was introduced by Mr. Parkinson from St. Vincent. 



4. Bermuda. — Collections were made by the late Prof. C. B. Adams, also by 

 Mr. R. Swift, Mr. Temple Prime, m3'self, and others. As to H. microdonta Dh. 

 extensively distributed as H. delitescens Sh. see ray remarks. Annals vii. p. 140. 



5. Cuba. — I have been liberallj' supplied with Cuban species, especially by 

 Prof. Poey, Dr. Gundlach, Mr. Shuttleworth, Bishop Elliott, <fec. Some errors 

 may be detected in the Catalogue arising from differences of opinion and also of 

 classification, of Poey and Pfeiffer. I should quote the following from Poey, 

 Mem. ii, p. 406 — " Helices roatrata P., marginelloides 0., Pazen^is Pi/., transi- 

 toria P., Arangiana Py.., Gutierrezi Pg., margiiudoides 0., wina P., varietates 

 sunt H Sagemonis; quod in itinere CI. J. Gundlach demonstratum est. Transi- 

 tiones exstant ; animal in omnibus idem est." As to H. Carpenteriaria Bland, see 

 Annals vii. p. 138. 



The occurrence in species belonging to Cyclostomacea, of a perforation at the 

 upper margin of the aperture, is peculiar, I believe, to those inhabiting Cuba and 

 the Bahamas. See Poey, Mem. ii. p. 40. 



6. Grenada and Grenadines. — Dr. W. Newcomb collected in Grenada, and I 

 have received shells from him, Rev. J. Parkinson, and Mr. R. Swift. 



7. Guadeloupe. — I have had comparatively few authentic specimens from the 

 French islands. Beau in his Catalogue (1858) excludes several species generally 

 attributed to this island. 



8. Haiti.— I am principally indebted for Haitian shells to M. Salle, Mr. Cuming, 

 and Mr. Swift. The discovery of Vitrina was made by Mr. Hjalmarson, in 1858.
