64 MR. R. F. TOMES ON MAMMALS FROM JAMAICA. [Feb. 26, 



Leach, a genus and species which have not until now, to the best of 

 my knowledge, been brought under notice, excepting by the unsatis- 

 factory description of the wretched type specimen of Dr. Leach. Of 

 this I shall have more to say in a subsequent communication. 



1 . MUS RATTUS. 



2. MuS TECTORUM. 



In so far as external appearances are concerned, these specimens 

 differ in no way from European ones. They must be regarded as 

 settlers in the island. 



3. Capromys brachyurus, Hill, in Gosse's Naturalist's Sojourn 

 in Jamaica, p. 471. 



A single specimen, which has not perhaps been sufficiently exa- 

 mined to determine with absolute certainty its synonymy. 



4. Arctibeus perspicillatus, Linn. sp. 



Phyllostoma jtei'spicillatum, Geoff. 



P. superciliatmn et P. obscurum, Pr. Max. 



Arctibeus jamaicensis, Leach & Horsfield. 



Arctibeus carpolegus, Gosse, Nat. Soj. in Jam. p. 271. 



Phyllostoma planirostre, Spix ? 



After the examination of many specimens from the West Indian 

 Islands and the continent of America, I am fully persuaded that they 

 are all referable to one species, and that that species is the Vesper- 

 tilio perspicillatus of Linnaeus. There is, I admit, considerable dif- 

 ference in the size of the different individuals, the island specimens 

 being smaller and darker-coloured than those from the mainland ; 

 but as this is the case with the other Bats which inhabit alike the 

 West Indian Islands and the continent of America, it cannot be ad- 

 vanced as evidence of these two being distinct species, but rather the 

 reverse. 



5. Arctibetjs brachyotus, Pr. Max. sp. 



Phyllostoma brachyotum, Pr. Max. 

 Arctibeus jatnaicensis, Gosse, Nat. Soj. in Jam. p. 271. 

 A. achradophilus, Gosse, Nat. Soj. in Jam. p. 271. 

 A. sulphureus, Gosse, Nat. Soj. in Jam. p. 271. 



I have compared the specimens in the present collection with the 

 types of A. jamaicensis, A. achradophilus, and A. sulphureus of Mr. 

 Gosse in the British Museum, and again with the specimen of Arcti- 

 bexts brachyotus formerly in the Museum of this Society, so named 

 by Mr. Waterhouse ; and find them to be identical. 



6. MONOPHYLLUS REDMANII, Lcach. 



Glossophaga caudifer, Geoff. ? 



Five specimens, obtained by Mr. Osburn in Oxford Cave, Man- 

 chester, in February 1859. I have compared some of these with 

 the type in the British Museum. It is probable that this is the 

 Glossophagu caudifer of M. Geoffroy St. Hilaire.
