FROGS OF COLOMBIA — COCHRAN AND GOIN 259 



dorsal stripes (such as there may be) on the back that tend to be inter- 

 rupted. 



Description. — USNM 71115 (cotype), from Cali, Cauca Valley, 

 Valle, Colombia, at 3,200 feet. Vomerine teeth in two short, heavy, 

 rounded patches lying close together between the choanae; tongue 

 three-fourths as wide as mouth opening, broadly cordiform, its 

 posterior border slightly free and very faintly notched. Snout mod- 

 erate, somewhat triangular in shape when viewed from above, some- 

 what truncate in profile, the upper jaw not extending beyond lower; 

 nostrils more lateral than superior, not projecting, their distance 

 from end of snout about one-third that from eye, separated from 

 each other by an interval equal to about two-thirds their distance 

 from eye. Canthus rostralis rounded, slightly defined; loreal region 

 slightly flattened, the upper lip not flaring strongly. Eye moderate, 

 its diameter equal to its distance from nostril; interorbital space about 

 the width of upper eyelid, which is relatively wide, slightly greater 

 than distance between nostrils. Tympanum distinct, about one-third 

 the diameter of eye, separated from eye by a distance slightly greater 

 than its own diameter. Fingers practically free of web, fourth finger 

 considerably longer than second, not quite reaching to disk of third 

 which covers the tympanic area; no rudiment of a pollex. Toes about 

 three-fourths webbed, third toe slightly longer than fifth, disk of 

 fourth just covering the tympanic area; an oval inner and a smaller, 

 indistinct rounded outer metatarsal tubercle; no tarsal ridge; no dermal 

 appendage on heel. Body not elongate, in postaxillary region about 

 equal to greatest width of head; when hind leg is adpressed, heel 

 reaches almost to nostril; when limbs are laid along the side, knee 

 and elbow overlap slightly; when hind legs are bent at right angles 

 to body, heels overlap moderately. A moderately developed fold of 

 skin (patagium) extends from the back of the upper arm to the side 

 of the body. Skin of upper parts smooth; skin of chest, belly, and 

 lower femur uniformly and very finely granular; a definite skinfold 

 across the chest; vocal sac apparently internal. 



Dimensions. — Head and body, 25.8 mm.; head length, 8 mm.; 

 head width, 8.5 mm.; femur, 12.8 mm.; tibia, 13.2 mm.; heel-to-toe, 

 16.3 mm.; hand, 7.6 mm. 



Color in alcohol. — This specimen is now a faded uniform pale 

 brown, above and below. 



Since much of the preserved material is old and somewhat faded, 

 we present the following description of fresh, unfaded material based 

 on three specimens, a male and two females, collected by Dr. Wilmot 

 A. Thornton, at Candeleria, near Cali, Valle, in June 1962. 



The adult females are rather dark brown above and heaviJy mottled 

 below. On one of the females are quite distinct postocular dorsolateral
