Allen — Two Undescribed West Indian Bats. 167 



Erophylla sezekorni syops, subsp. now 



Type, an adult male (alcoholic with dry skull), 13,713 M. C. Z., col- 

 lected at Montego Bay, Jamaica, March 14, 1912, by Joseph A. Cushman. 



General characters. — Structurally similar to E. sezekorni and E. s. 

 planifrons, but the skull differing conspicuously in its wider rostrum with 

 molar rows nearly parallel instead of converging anteriorly; profile very 

 little less elevated than in sezekorni, but lachrymal region more swollen; 

 the palate narrower ; teeth slightly broader throughout. 



Measurements. — The type measures : forearm, 48 mm.; tibia, 23; foot, 

 14.6; tail from anus, 14.5; ear from meatus, 17. Skull: greatest length, 

 24.7; basal length, 20 ; palatal length, 11; zygomatic width, 11.6; width 

 outside m 2 , 6.5; upper tooth row (front of canine to back of m 3 ), 8; lower 

 tooth row (front of canine to back of m 3 ), 9. 



Specimens examined. — Eight, all from the type locality. 



Remarks. — The Jamaican Erophylla is only slightly different from that 

 of Cuba and the Bahamas, but more closely resembles the former. The 

 Bahaman race has an even flatter profile and a more pointed rostrum. 

 Dry skins are not available to show if there are color differences. The 

 specimen of E. sezekorni from which Miller in 1899 made his diagnosis 

 must have been somewhat abnormal, for he says the "crown of the first 

 lower molar is only slightly longer than that of the first premolar," 

 whereas in normal specimens it is as in other forms, about twice the 

 length of the first premolar. 



The interesting genus Chilonycteris is found in tropical Amer- 

 ica from Brazil to Mexico on the mainland, but in the West 

 Indies is as yet known from the Greater Antillean islands only. 

 Three distinct species occur here, a smaller, an intermediate, 

 and a larger, distinguished not only by size but by various slight 

 structural peculiarities. While representatives of all three species 

 have been found only in Cuba so far, it is likely that future ex- 

 ploration will discover the three species on the other large islands 

 of the group as well. At the present time, Chilonycteris mac- 

 leayii, the first of the West Indian forms to be named, is known 

 from the typical form in Cuba, and a closely allied subspecies, 

 C. m. grisea, in Jamaica. Possibly the Porto Rican inflata of 

 Rehn is a representative of this species, but I have as yet seen 

 no specimens of it. 



The next Antillean species to be described is C. fidiginosa of 

 Haiti and Santo Domingo. This is the smallest of the three, and 

 apart from its small size is readily distinguished from the mac- 

 leayii group by the small tubercles rimming the nose pad, which 

 in macleayii is surmounted by a plain-edged angular projection.
