PHTI-LOSTOMID.'E. 



longitudinal ridge ; tongue very long, much attenuated in its terminal 

 fourth, and flattened, the centre naked above and beneath, the sides 

 set with long filiform papiUse directed backwards ; lower lip widely 

 grooved above and also in front, the edges of the groove margined 

 with small warts. 



Thumb weU developed, with a large claw ; first phalanx of the 

 middle finger less than half the length of the metacarpal bone; 

 wings from the ankles ; calcaneum half the length of the foot ; in- 

 terfemoral membrane concave behind, extending as far back in the 

 middle line as the centre of the tibia ; tail very short, the extreme 

 tip appeai'ing upon the upper surface of the membrane. 



Fur, above, dark brown, paler towards the base of the hairs ; be- 

 neath, similar, but paler ; moderately long, scarcely extending upon 

 the volar membranes, but the metacarpal bone of the thumb is 

 clothed with short hairs ; the face is covered to the extremity of the 

 muzzle with short fur, and several single, fine, long hairs spring from 

 the muzzle in front of the eyes and behind the chin. 



Upper incisors in a semicircular row between the canines, all close 

 together ; the central pair chisel-shaped, larger than the outer ones, 

 which have oblique cusps slanting downwards and inwards ; lower 

 incisors equal, cylindrical, flat-crowned, in a convex row (Plate 

 XXVII. fig. 2) ; upper canines with a projecting cingulum behind ; 

 upper premolars narrow, triangular, nearly equal; the first pre- 

 molar separated from the canine by a small interspace, the remain- 

 ing teeth close together ; first and second upper molars almost equal, 

 with narrow W-shaped cusps, and horizontal base projecting in- 

 wards ; last upper molar three fourths the antepenultimate molar ; 

 lower premolars equal in size as in upper jaw ; molars narrow, with 

 blunt cusps.

Hah. Tropical parts of the Neotropical Eegion, probably generally 

 distributed. In the Mexican, Brazilian, and Chilian Subregions, 

 recorded from Mexico (Tehuantepec, Oaxaca), Guatemala (Coban), 

 Costa Eica, Yenezuela, Island of Trinidad, British Guiana, Surinam, 

 Brazil, Upper Amazons, Peru, Bolivia; and in the Antillean Sub- 

 region, from Jamaica and the Isle of Grenada. 



This species is so widely distributed and so abundant in the 

 Neotropical Eegion, that examples of it are fomid in almost every 

 collection made in the tropical parts of that region, and this has led 

 to the very great list of synonyms which preface the description. 

 The synonymy of this and of the other species of the group Glosso- 

 phagse has been most carefully worked out by Dr. Peters in his 

 paper referred to above. The original description, published by 

 Pallas more than one hundred years ago, leaves little to be desired ;
