62 THE NAUTILUS. 



described it under the name of Buliviulus Hemphilli in tlie West 

 American Scientist of April, 1889. 



During the present season I have had the opportunity to compare 

 the animals, eggs and habits with typical B. Dorvumi and no doubt 

 is left as to its being distinct from it. But as to its relation to B. Flori- 

 danns I am not able to say so positively, never having seen this un- 

 known shell. However I claim the following differences appear from 

 comparison with the published figure and description. See Bin- 

 ney's American Land Shells, p. 407-8, fig. 448. 



B. Hemphilli Wright. 



Imperforate. 



Wide. 



Amber dull lead color. 



Obscure brownish red bands below. 



Spire blunt, short. 



Aperture § length of shell. 



Ba'ie uniformly and gracefully 



rounded. 

 Expanded at base. 

 Whorls 5. 

 Marked by coarse lines of growth. 



I call this quite a " general difference." and from which I believed 

 myself justifiable in giving to it a name, especially after receiving 

 the following letter from Dr. Binney : 



August 16. 1888. " I find the jaw and lingual dentition to be 

 same as in B. nitelinus Rv. — B. serperastrus Say." August 26, 

 1888. "I am aware that said figure (449) does not agree with the 

 carinated body whorl of B. F/oridanus, but in the present state of 

 our ignorance of the range of variation of these Bulinii, who 

 knows ? " 



" It would be well for you to describe your shell as new, leaving 

 to the future the decision of its identity with some other W. I. or 

 Spanish Main species. To us Americans, it is surely new." 



I am thus specific about this because Dr. Binney has subsequent- 

 ly (see last Ed. of Manual of American Land Shells) placed B. 

 Hemphilli Wright, as a synonym of B. Floridamis. Why he should 

 do so, after the above declaration, is strange to me, unless he is natur- 

 ally too conservative. 

 Who has seen it — Bulimulus Floridanus Pfr. ? 



After seven years spent in Florida, travelling about much and al- 

 ways keeping a sharp look-out for shells and plants, I have never
