and inner margins decreasingly convex upwards, very narrowly 

 rounded off above ; tragus as in Phylhstoma hccstatum, but longer and 

 more attenuated above ; horizontal nose-leaf very similar to that 

 of MacropJiyllum neuwiedii, rather narrow and square in front and 

 bound down to the upper lip, the vertical leaf as broad as it in 

 the centre, quite equal in length to double its width, lanceolate, 

 attenuated in upper third, with a central ridge forming the narrow 

 terminal projection above ; chin with a transverse naked space in 

 front, divided in the centre by a narrow groove (Plate XXV. fig. 6). 



AYings from the ankles or tarsus ; calcaneum as long or slightly 

 longer than the tibia ; interfemoral membrane very deep, extending, 

 when fully stretched, behind the feet ; tail short, as iu Phylhstoma 

 hastatum. 



Fur above cinnamon - brown, paler beneath ; on both surfaces 

 long and dense, covering the humerus, but scarcely extending to 

 the membranes. 



Central upper incisors moderately long, unicuspidate, chisel-shaped, 

 directed vertically downwards ; outer incisors very short, scarcely 

 raised above the gum ; lower incisors smaU, grooved in front and 

 above ; upper premolars as in Phyllostoma, lower equal in cross 

 section at base, but the first is shorter and more obtuse. 



Length, head and body about 2"-6, taU. l"-5, ear l"'l, tragus 0"'4, 

 thumb 0"-45 ; third finger— metacarp. l"-7, 1st ph. 0"-8, 2nd ph. 1", 

 3rd ph. 0"-7 ; fourth finger— metacarp. l"-65, 1st ph. 0"-6, 2nd ph. 

 0"-7 ; fifth finger— metacarp. l"-8, 1st ph. 0"-6, 2nd ph. 0"-65 ; 

 tibia 0"-75, calcaneum 0"-8, foot 0"-65. 



Hah. Mexico ; South America. 



This species is founded on a single specimen, a skin in bad con- 

 dition, of which the greater part of the skull has been removed, and 

 the lower jaw is broken across in the middle, so that it is doubtful 

 whether a minute second premolar does not exist.
