On Molluscafrom the Island of Dominica. 227 



XXIX. — On the Mollusca collected hy Mr. O. A. Ramage at 

 the Island of Dominica. By Edgar A. Smith *. 



With the exception of a small Vagi7iula none of the fifteen 

 species of terrestrial Mollusca in the collection made by Mr. 

 Ramage are new to the fauna. 



Mr. R. J. Lechmere Guppy f was the first to attempt a 

 complete list of the terrestrial forms occurring in Dominica, and 

 this list with some modifications was reproduced by Kobelt J 

 in his series of papers on the distribution of land-mollusks. 

 Twenty species are there enumerated,, of which nine are said 

 to be peculiar to the island, the remaining eleven being met 

 with on one or other of the neighbouring islands. 



In 1881 Mr. A. D. Brown § criticized some of Mr. Guppy's 

 observations respecting the distribution of certain forms, and 

 gave a list of twenty species collected by himself. Eight of 

 these are not quoted by Mr. Guppy. 



An abstract of Mr. Brown's paper is given in the ' Journal 

 of Conchology,' vol. iii. p. 182. 



Mr. G. F. Angas || has since published an account of the 

 species he collected during a short visit in the early part of 

 the year 1883. Of the twenty species he obtained three are 

 new to both Brown's and Guppy's catalogues. Altogether, 

 including the new species of Vaginula, the total number of 

 species from Dominica now amounts to thirty-three. Ten of 

 these, so far as at present known, are peculiar to the island, 

 and the remainder are variously distributed ; about five of 

 them occur as far north as Porto Rico, three or four at St. 

 Vincents and St. Kitts, two or three at St. Thomas, and two 

 species at Barbados. More species, however, are common to 

 Guadeloupe and Martinique than to any other of the islands, 

 and this, from their greater proximity to Dominica, would 

 naturally be expected. A few species, however, range beyond 

 the West Indies, one or two occurring in Mexico, one at 

 Panama, one in Peru, and another in Bolivia. 



* This collection forms part of the first consignment of specimens 

 recently received from Mr. Ramage, who, under the auspices of a joint 

 committee of the Royal Society and the British Association, is making 

 collections of the fauna and flora of the Lesser Antilles. The species 

 collected by Mr. Ramage are marked with an asterisk in the list 

 appended.
