NO. 5 MAMMALS OF PANAMA GOLDMAN 201 



Genus VAMPYRODES Thomas 



The genus Vampyrodes is very similar to the genus Vampyrops, 

 but has two instead of three molars in each upper jaw, the small last 

 molar present in the latter genus being absent. A more important 

 character, however, is the suppression of the metacone in the second 

 upper molar. The genus Vampyrodes outwardly somewhat resembles 

 the genera Uroderma and Chiroderma, but the differences in size of 

 the Panama representatives of these genera suffice to separate them. 

 The teeth are 30 in number. 



VAMPYRODES MAJOR G. M. Allen 



San Pablo Bat 



Vampyrodes major G. M. Allen, Bull. Mus. Comp. Zool., Vol. 52, No. 3, p. 38, 

 July, 1908. Type from San Pablo, Isthmus of Panama. 



Vampyrodes major is a rather large bat with a pair of broad white 

 face stripes extending from the nose backward, one on each side, 

 over the eye to above the ear, and with a white line extending from 

 the top of the head down the middle of the back. Another white 

 mark extends from near the corner of the mouth to the ear. These 

 stripes are shared with Uroderma bilobatum and Vampyrops helleri^ 

 but the greater forearm measurement, about 55.5 millimeters, is 

 distinctive. 



V. major is known in Panama only from the type locality, a place 

 now covered by the waters of Gatun Lake. A specimen also in the 

 Museum of Comparative Zoology was collected at Cerro Santa 

 Maria, Costa Rica, by C. F. Underwood, January 5, 1908, and the 

 species may be expected to occur anywhere in the general region. 



Specimens examined : San Pablo, 1 (type). 1 



Genus VAMPYRESSA Thomas 

 The genus Vampyressa includes very small species with the white 

 facial markings of Artibens; it agrees further with that genus in the 

 absence of a dorsal stripe, but the ears are shorter and more rounded. 

 There is no external tail and the narrow interfemoral membrane is 

 densely furred to the margin as in Vampyrops. The skull is similar 

 in general contour to that of Vampyrops, but the molars are reduced 

 to two on each side above and below. As in that genus the median 

 upper incisors are separated by a distinct gap, but the cutting edge is 

 bifid instead of smooth. The teeth are 28 in number.
