FROGS OF COLOMBIA — COCHRAN AND GOIN 



305 



short, rounded when viewed from above, slightly pointed in profile, 

 the upper jaw extending beyond lower; nostrils as lateral as superior, 

 slightly projecting, their distance from end of snout about one-half 

 that from eye, separated from each other by an interval equal to 

 about their distance from eye. Canthus rostralis rounded, not strongly 

 defined; loreal region a little rounded and nearly vertical, the upper 

 lip not flaring out below it. Eye large and prominent for a frog this 

 size, its long diameter definitely greater than its distance from nostril ; 

 palpebral membrane not reticulate; interorbital distance about 

 equal to width of upper eyelid, which is relatively wide and slightly 

 greater than distance between nostrils. Tympanum very distinct, 

 about one-third the diameter of eye, separated from eye by a distance 

 nearly equal to its own diameter. Fingers webbed at base, the web 

 extending to or onto the bases of penultimate phalanges of digits 

 2, 3, and 4; fourth finger considerably longer than second, just reaching 

 to disk of third which snugly covers the tympanic area; no projecting 

 rudiment of a pollex; no ulnar ridge. Toes more than one-half webbed, 

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

 and fifth toes subequal, disk of fourth toe very nearly covering the 

 typanic area; a distinct oval inner and a smaller indistinct rounded 

 outer metatarsal tubercle; no tarsal ridge; no dermal appendage on 

 heel. Body not elongate, in postaxillary region a little narrower than 

 greatest width of head; when hind leg is adpressed, heel reaches al- 

 most to anterior margin of eye; when limbs are laid along the side, 

 knee and elbow meet snugly; when hind legs are bent at right angles 

 to body, heels overlap. A patagium extends from the back of upper
