other than that of Dobson (1878, p. 501), who notes specimens in the 

 British Museum from Grenada and " ? Isle of St. Vincent." As this 

 was before longirostris was discriminated, it seems likely that these 

 references are to that species. On the Venezuelan coast, Robinson 

 found longirostris the commoner of the two species of Glossophaga, 

 in the proportion of 12 to 1. 



In the type specimen of G. longirostris, the lower incisors are entirely 

 wanting, although their alveoli are distinctly visible. Among a series 

 of thirty-four specimens, also from the Santa Marta Mountains, 

 Colombia, in the collection of the American Museum of Natural 

 History, "the incisors are all present in both jaws" in nearly one half 

 of the individuals; "in about one-third of the series they are entirely 

 absent in both jaws; in the remainder some of the incisors are present 

 and the alveoli of those lacking are clearly indicated. /Apparently 

 they are absent, as a rule, only in old specimens " (J. A. Allen, 

 Bull. Amer. Mus. Nat. Hist., 1900, 13, p. 90). All the incisors are 

 present in our series of eleven adults from Grenada, but only five of 

 the thirteen specimens from Carriacou have the entire number. Of 

 the eight in which the number of incisors is incomplete, three have 

 lost one or other of the first lower incisors; one has lost the lower 

 right and the upper left incisors; one, the lower right first and second, 

 and left upper second incisors; one has lost all the lower incisors 

 but the second on the left side; and one has lost the left upper second 

 incisor only. As might be expected, therefore, it is the first lower 

 incisor that is commonly the first to go. As originally suggested by 

 Mr. G. S. Miller Jr., this species is doubtless in process of losing the 

 lower incisors, and is thus approaching the condition found in the 

 related genera, Lichonycteris, Choeronycteris, and Hylonycteris, which 

 have quite lost these teeth. 



Glossophaga soricina antillarum Rehn.

 delphia, 1902, p. 37. 



The type and two other specimens of this subspecies came from Port 

 Antonio, Jamaica, where they were collected in December, 1890. 

 In a letter to the writer, Mr. Rehn suggests that this race is perhaps 

 nearer to longirostris than to soricina; but on geographical grounds 

 this seems doubtful although no careful comparison of the two has 

 yet been made. The forearm measurement is given as 38 mm.; ex- 

 treme length of skull, 22.5, as against 35 and 20 or 21 for the corre-
