FROGS OF COLOMBIA — COCHRAN AND GOIN 221 



flaring somewhat below it. Eye moderate, not prominent, its diameter 

 slightly greater than its distance from nostril; interorbital distance 

 half again as wide as upper eyelid, which is relatively wide, and about 

 equivalent to distance between nostrils. Tympanum distinct, small, 

 about one-fourth the diameter of eye, separated from eye by a dis- 

 tance nearly equal to its own diameter. Fingers one-third webbed, 

 fourth finger but slightly longer than second, just reaching to disk of 

 third which is half again as broad as the tympanic area; no projecting 

 rudiment of a pollex; a well-developed fold from the elbow along the 

 ulnar side of the arm to the wrist. Toes about three-fourths webbed, 

 the web on fourth toe reaching base of the penultimate phalanx, 

 third and fifth toes subequal, disk of fourth toe covering the tympanic 

 area; metatarsal tubercles not distinct; a very distinct tarsal fold 

 continuing to the heel where it terminates in a small but distinct 

 triangular appendage, tarsal fold somewhat whitish in color, a similar 

 fold above vent, which makes contact with that on leg when limbs 

 are folded; and on each side, anterior to groin, is a little fold which 

 seems to be a structural feature. Body not elongate, in postaxillary 

 region about equal to greatest width of head; when hind leg is ad- 

 pressed, heel reaches between eye and nostril; when limbs are laid 

 along the side, knee and elbow touch; when hind legs are bent at 

 right angles to body, heels overlap slightly. A patagium extends from 

 the back of the upper arm to the side of the body. Skin of upper 

 parts very finely granular; a quite distinct but rather narrow glandular 

 ridge encircling upper part of tympanum; skin of throat and chest 

 finely granular, that of belly and lower thigh uniformly and finely 

 granular; traces of a skinfold across the chest; no inguinal gland; no 

 apparent vocal sac. Skin of head not co-ossified with skull, roof of 

 skull not exostosed. 



Dimensions. — Head and body, 41.5 mm.; head length, 13.8 mm.; 

 head width, 14 mm.; femur, 20.1 mm.; tibia, 21.7 mm.; foot, 29.5 

 mm.; hand, 13.5 mm. 



Color in alcohol. — A faded yellow all over except for scattered, 

 brownish, pepper-like markings on middle of back. 



Remarks. — Although the large cotype of palmeri is firm and exceed- 

 ingly well preserved while the cotypes of albopunctulata are quite soft 

 and flabby, it is evident that they all are the same species. The reason 

 for the name is evident, for in one of the cotypes of albopunctulata the 

 entire dorsal surface, including that of the limbs, is well-marked with 

 scattered, clear white spots about the size of a pencil dot. A few white 

 spots can be seen on two of the other cotypes, but the cotypes of 

 palmeri (BM 1908.5.29.68-9 [1947.2.13.32-3]), the cotype of albo- 

 punctulata from Sarayacu (BM 80.12.5.230) and another one (80.12.5.- 

 159) from "Ecuador" lack these white punctulations. In all the speci-
