FROGS OF COLOMBIA — COCHRAN AND GOIN 157 



not notched. Snout moderate, somewhat triangular when viewed 

 from above, slightly rounded in profile, the upper jaw extending 

 slightly beyond lower; nostrils more lateral than superior, very 

 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; distance from nostril to anterior 

 corner of eye about equal to distance from anterior to posterior 

 corners of eye. Can thus rostralis well defined; loreal region slightly 

 concave and nearly vertical, the upper lip flaring out but very slightly 

 below it. Eye moderate, protruding, prominent, its diameter equal 

 to its distance from nostril; palpebral membrane not reticulate; 

 interorbital distance as great as width of upper eyelid, which is 

 relatively wide and slightly greater than distance between nostrils. 

 Tympanum distinct, about one-third the diameter of eye, separated 

 from eye by a distance nearly equal to its own diameter. Fingers with 

 a trace of web between second and third and between third and 

 fourth, fourth finger about one-half disk longer than second, reaching 

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

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

 webbed, the web on fourth toe reaching to base of the antepenultimate 

 phalanx, third toe slightly longer than fifth, disk of fourth covering 

 about two-thirds the tympanic area; a distinct oval inner but no 

 apparent outer metatarsal tubercle; no tarsal ridge; a wart-like dermal 

 appendage on heel. Body moderately elongate, in postaxillary region 

 distinctly narrower than greatest width of head; when hind leg is 

 adpressed, heel reaches eye; when limbs are laid along the side, knee 

 and elbow just meet; when hind legs are bent at right angles to body, 

 heels overlap greatly; thighs thin and Hyla-\ike. No patagium. Skin 

 of upper parts smooth; no structural dorsolateral folds evident; a 

 rather narrow glandular ridge passing above tympanum; skin of throat 

 and chest smooth, that of belly and lower surface of thigh uniformly 

 granular; no apparent traces of a skinfold across chest; adult (?) 

 female, no vocal sac apparent. Skin of head not co-ossified with skull, 

 roof of skull not exostosed. 



Dimensions. — Head and body, 39.3 mm.; head length, 14.6 mm.; 

 head width, 14 mm.; femur, 17.3 mm.; tibia, 21.1 mm.; heel-to-toe, 

 29.4 mm.; hand, 13.4 mm. 



Color in alcohol. — Dorsum dark gray with scattered, distinct, 

 more or less rounded yellow spots. These spots range from one-half 

 to two-thirds the diameter of tympanum. Between axilla and groin 

 are a series of rather distinct — in some cases nearly vertical — black 

 blotches. Each thigh is crossed by three distinct, broad, black bands 

 which extend down onto the anterior and posterior faces of the thigh 

 but which fail to meet on the undersurface of the thigh. Paler but
