Distribution. — The island of Jamaica, specimens having been 

 recorded from the type locality, Kingston and Oxford Cave, while 

 other individuals have been examined from Lucea, Hanover Parish, 

 in the extreme northwestern part of the island. 



General Characters. — Size quite large, largest of the madeayii group; 

 nostrils with the superior margin deeply and squarely emarginate cen- 

 trally. 



Head. — Similar to C macleayii with the following exceptions: Nos- 

 trils with the superior margins bearing two low quadrate peg-like pro- 

 jections, between which is a deep emargination completely separating 

 them; process flanking the nostrils elongate, sublanceolate in char- 

 acter. Dobson's figure {vide supra) represents these characters very 

 clearly and was no doubt taken from the type specimen presented 

 by Gosse, as that was the only Jamaican specimen studied by him. 



Limbs. — Similar in character to C. macleayii, but, of course, larger, 

 though the proportions are practically the same. 



Membranes and Fur. — As in macleayii, but the free margin of the 

 uropatagium very curiously tucked and thickened by short longitudinal 

 thickenings, a character well exhibited in Gosse's original plate of the 

 species. 



Color. ^^ — Rufous phase: above ferruginous; below chestnut, becom- 

 ing pale on the chin; ears and cephalic processes vinaceous-cinnamon, 

 the former becoming pale drab apically; volar membranes mummy- 

 brown. Brown phase: above bistre, sprinkled and suffused with sil- 

 very-white as in the brown phase of the other races of the macleayii 

 group; beneath clove-brown; membranes as in the rufous phase. 



Skull. — Elongate, somewhat compressed; rostrum slenderer, com- 

 paratively, than in any of the other forms of the macleayii group; 

 brain-case moderately inflated. 



Teeth. — As in C. macleayii, except for the first lower premolar which 

 is broader, with the external margin more rounded than in the typical 

 form. 



Measurements. — Average of series: Total length [4] 68.7 (66.5-74); 

 head and body [4] 45.4 (44.5-49) ; head [2] 18.3 (18.2-18.5) ; ear [4] 15.2
