within about 1 mm. of the free border of the iiiterfemoral membrane ; it, too, seems 

 to consist of four vertebrae in the membrane, the terminal one of which is smallest 

 and apparently somewhat cartilaginous. In No. 39S4 the tail is still further re- 

 duced, and extends to within but 3 mm. of the free edge of the membrane, and 

 only three external vertebrae are with certainty distinguishable. 



Vampyrops lineatus (E. Geoffroy). 



A series in alcohol from eastern Brazil (Bahia, Macaco, Minas Geraes) is 

 referred to this species. The average forearm measurement of nine individuals is 

 47.7 mm., which closely approximates that (46 mm.) given by Lyon for a speci- 

 men from Paraguay, the type locality. 



Vampyrodes major, sp. nov. 



Type. — k&ult female, alcoholic, No. 6756, Museum of Comparative Zoology; 

 collected at San Pablo, Isthmus of Panama, by Allen Lesley. 



General Characters . — Allied to Vampyrodes caracciolae Thomas, but larger 

 throughout. 



Description of Type. — It is now impossible to say what was the original color 

 of the type, as it has been preserved in spirits for a number of years. The color 

 of the fur in alcohol is burnt umber dorsally, similar but paler below. Two broad 

 white stripes, starting one on each side of the nasal eminence, and 4 mm. apart at 

 their origin dorsally, pass backward slightly above the eye to the upper posterior 

 root of the ear. These stripes are about 3 mm. broad throughout. A second 

 white stripe, less well defined, runs from below the anterior corner of the eye on 

 each cheek to the outer base of the ear. A very narrow white stripe runs medi- 

 ally from the occiput to the end of the spine. Tips of the wings whitish. 



Dorsally the fur extends out on the wing membranes as far as a line joining 

 the elbow and the knee and along the dorsal surface of the forearm. There is a 

 slight pubescence at the base of the thumb. The hind limbs are practically naked 

 save for a few scattered short hairs; interfemoral membrane with a few long 

 hairs from the median border ; inferior surfaces of the membranes naked ; base of 

 the ears, posteriorly, covered with fur, and a thin tuft of long hairs on the inner 

 anterior margin of the conch. 



Nose leaf well developed, its anterior border free, horseshoe-shaped ; the erect 

 portion broadest at the base, tapering to the pointed summit, and with a central 

 thickened, mitre-shaped area. On the lower lip is a large median glandular swell- 

 ing, rounded, with a smaller oval swelling at each side at the edge of the lip. A 

 row of five or six small roundish glands runs from the edge of the lip on each side 

 down below the large central gland. A curved glandular swelling is present at 

 the base of the nose leaf on each side. 



Inner margin of ear, regularly convex, summit rounded and somewhat flattened ; 

 upper half of outer margin nearly straight ; lower half convex to the basal lobe,
