New Glossophagine Bats from the West Indies. 35 



thumb at distal end of metacarpal. The membranes are practically naked 

 throughout, as the fur of the body reaches the wings (both above and 

 below) in a narrow line only. 



Feet. The foot is long and strong, about two-thirds length of tibia. 

 Toes essentially equal in length, the first and fifth slightly shorter than 

 the others. Claws large and sharp, nearly one-third as long as rest of 

 foot. Calcar distinct but reduced to a mere stub 3 mm. in length. 



Tail. Tail slightly longer than foot, a little less than half free from 

 membrane. 



I'\ir and color. The fur is loose in texture, and only moderately long 

 (about 10 mm. at middle of back). It is closely confined to body, scarcely 

 reaching wings. That of head covers external basal fourth of ears. 

 Face densely hairy as far forward as ridge behind noseleaf. Chin and 

 noseleaf naked. Lips and ridge behind noseleaf sprinkled with fine, 

 short hairs. 



Color of two skins (topotypes) collected June 3, 1884, by C. J. May- 

 nard (Nos. 85 and 86, Miller collection) : fur of back whitish gray through 

 basal half, then light clay color faintly tinged with pinkish buff. The 

 pale bases of the hairs appear irregularly at the surface. Ventral surface 

 pinkish buff, the hairs grayish at base. Ears, membranes, and feet light 

 brown. After thirteen years' immersion in alcohol the color of the type 

 does not differ appreciably from that of these skins. 



K!;ull. The skull of Phyllonycleris planifrons differs from that of P. xeze- 

 korui most noticeably in the presence of very slender but complete zygo- 

 matic arches. The rostrum is slightly broader and flatter and the brain- 

 case smaller relatively to the size of the skull. The facial profile is straight 

 from external nares to base of proencephalon, where it rises at an angle 

 of about 12. Proencephalon small, indistinctly marked oft* from very 

 large mesencephalon. Metencephalon small and slightly outlined. Lach 

 rymal region abruptly swollen. Antorbital foramen placed obliquely over 

 posterior part of second premolar. Bony palate slightly arched, its gen 

 eral form nearly rectangular, the width between penultimate molars about 

 half length. Vacuities behind incisors smaller than in P. sezekorni, but 

 distinct. Pterygoids long, the distance from hamular to posterior molar 

 slighlly greater than length of tooth row behind canine. The pterygoids 

 are strongly hollowed from within ; and the interpterygoid fossa is partly 

 closed in immediately behind the bony palate by the thin shelf-like edges 

 of the pterygoids. Ventral aspect of roof of posterior nares flat. A 

 slight depression on each side of the faint median ridge on basioccipital 

 between audital bullse. Audital bulke small and round, their greatest 

 diameter about equal to least width of palate between second premolars. 

 Rim of external nares thick, not flaring. Mandible slender, the depth 

 contained about seven times in greatest length. 



The skull of the type measures: greatest length 25; basal length 22; 

 basilar length 20 ; zygomatic breadth 11 ; interorbital breadth 4.8; lach 

 rymal breadth 6 ; mastoid breadth 11; fronto-palatal depth 3.4 ; depth 

 of braincase from highest point to level of audital bullte 9.6 ; maxillary
