2. Chiroderma villosum. 

 Chii-oderma villosum, Petei-s, MB. Akad. Berl. I860, p. 748. 



Ear-conch as in Artibeus perspicillatus ; nose-leaf also nearly 

 Bimilar, smaller, and circular in front ; a faint white streak on each 

 side above the eye from the nose-leaf to the ear, no white line along 

 the spine. 



Fur moderately long, pale yellowish brown above, with darker 

 brown extremities ; beneath darker brown, the extreme tips greyish. 

 Above, three foiirths the forearm is thickly covered, also portion of 

 the wing-membrane posterior to it, and along the sides of the body 

 as far outwards as a line drawn from the elbow to the knee, also 

 upon the legs and interfemoral membrane, thinning out towards the 

 aiikles, and thinly upon the posterior margin of the interfemoral and 

 upon the backs of the feet. 



Interfemoral membrane about as large as in Artibeus perspicil- 

 latus, but much more densely clothed with hair. Wing-membrane 

 extending to the metatarsus. 



Skull broadly conical in front, the width between the outer edges 

 of the posterior upper molars slightly exceeds the length of the 

 tooth-row, measured from the inner incisor to the posterior margin 

 of the last molar. Frontal bones flat, with very short postorbital 

 processes ; nasal aperture continued backwards by an oval slit, 

 which reaches as far backwards as a line drawn between tbe most 

 anterior parts of the bony orbits ; bony palate continued as far 

 backwards as the posterior third of the zygoma.

Tipper middle incisors slender, unicuspidate, their oblique cusps 

 directed inwards towards the middle line and close together by their 

 extremities ; outer incisors imicuspidate, conical, slightly exceeding 

 the cingulum of the canine, not iilling up the space between the 

 canine and the middle incisors ; first upper premolar small, with a 

 very oblique cusp directed forwards and touching the canine, but 

 separated from the second large premolar by a space ; last upper 

 molar exceeding the first in size ; lower incisors equal, not crowded, 

 not grooved ; first lower premolar with a broad base, the cingulum 

 projecting considerably behind, forming a small posterior cusp ; 

 second with a broad base and a long slender anterior cusp ; last 

 molar nearly double the length of the antepenultimate molar, with 

 a flat crown margined by five small cusps (Plate XXIX. figs. 2, 2 a). 



Distance between outer edges of posterior upper molars 0"'52, 

 distance between summits of cusps of canines 0"-2, length of upper 

 tooth-row 0"-5. 



Length, head and body about 2""4, interfemoral membrane in the 

 middle 0"-3, ear 0"-65, forearm 2", thumb 0"'5 ; third finger — 

 metaoarp. l"-9, 1st ph. 0"-8, 2nd ph. 1"-1, 3rd ph. 0"-8 ; fifth finger 

 — metacarp. l"-9, 1st ph. 0"-5, 2nd ph. 0"-65 ; tibia 0"-7, calcaneum 

 0"-35, foot 0"-5.
