Crlandina perlucens. Helicina epistilia. 

 Bulimulus latieinctus. " humilis. 



" stenogyroides. " vclutina. 



Amphibulima pardalina. " conuloides. 



Cyclotus amethystinus. 



Formirfg his judgment from the soft parts and the lingual den- 

 tition, Mr. Guppy separates Amphibulima as a genus from Suc- 

 cinea : 



Amphibulima. Type A. patula. 



•Omalonyx (s. gen.) " A. unguis. 



Brachyspira " " A. pardalina, A. tigrina. 



On the shells of Grenada, the author remarks that the genus 

 Stenopus cannot be allowed to stand, having been preoccupied 

 for a crustacean. We do not agree with him : generic names in 

 Natural History have become so numerous, that it is demand- 

 ing too much of the Conchologist, the Ornithologist or Naturalist 

 devoted to any other speciality, that he shall be acquainted with 

 them all, or know where to look for them at a vast expenditure 

 of time, in the thousand and one publications in which theyhave 

 appeared. Moreover, there is scarcely a library in the world 

 which contains all of these publications. It is enough that the 

 describer shall have ascertained that the genus has not been 

 used previously in his own branch of study. That this rule has 

 been practically adopted, notwithstanding the letter of the law 

 to the contrary, is evidenced by the numerous synonymous names 

 in the various branches of Zoology, which pass unquestioned. 

 In this very number of the Annals we find a Dipsas ochraceus, 

 a fish described, the genus Dipsas being also used in Conchology. 



Tomatellina lamellata, Pot. and Mich. T. Funcki, of Mr. 

 Bland's list of Grenada Shells, is identical with T. Blandiana, 

 Pfr., described from Trinidad, and both are referred by Mr. 

 Guppy to the above. 



Bulimulus indistinctus, a new species, is described. 



The following new species are described from Trinidad:* 

 Spiraxis simplex. Helix bactricola. 



Stenogyra plicatella. Pupa uvulifera. 



" coronata. " auriformis. 



Zonites implicans. Helicina ignicoma. 



" umbratilis.

 Adams. 



* Mr. Thos. Bland contributes a paper to the present issue of the 

 Journal, in which Mr. Guppy's labors are thoroughly reviewed.
