FROGS OF COLOMBIA — COCHRAN AND GOIN 343 



more pointed than rounded when viewed from above, truncate in 

 profile, the upper jaw extending but slightly beyond lower; nostrils 

 lateral, somewhat projecting, their distance from tip of snout about 

 equal to their distance from eye, separated from each other by an 

 interval about equal to their distance from eye. Canthus rostralis well 

 defined; loreal region somewhat concave and nearly vertical, the upper 

 lip flaring out but very slightly below it. Eye moderate, not particularly 

 prominent, its diameter half again as great as its distance from nostrils; 

 palpebral membrane not reticulate; interorbital distance slightly 

 greater than width of upper eyelid, which is about equal to distance 

 between nostrils. Tympanum very distinct, about three-fifths the 

 diameter of eye, separated from eye by a distance equal to one-half 

 its own diameter. Fingers unw ebbed, fourth finger considerably longer 

 than second, reaching to middle of disk of third which covers about 

 two-thirds the tympanic area; no projecting rudiment of a pollex; 

 ulnar ridge a row of very low, white, rounded, wart-like structures. 

 Toes unwebbed, the first toe longer than second, much longer than 

 third, disk of fourth covering about one-half the tympanic area; a 

 distinct oval inner and a smaller but equally distinct rounded outer 

 metatarsal tubercle; no tarsal ridge; no dermal appendage on heel. 

 Body elongate, in postaxillary region distinctly narrower than greatest 

 width of head; when hind leg is adpressed, heel reaches anterior border 

 of tympanum; when limbs are laid along the side, knee and elbow 

 overlap slightly; when hind legs are bent at right angles to body, heels 

 overlap greatly. No patagium. A low but distinct glandular dorsolateral 

 fold extends on each side from behind eye to region of sacral hump. 

 Skin of throat and chest finely granular, that of belly and lower 

 surface of thigh uniformly and more coarsely granular; no trace of a 

 skinfold across chest; adult female, no vocal sac. Skin of head not 

 co-ossified with skull, roof of skull not exostosed. 



Dimensions. — Head and body, 91.5 mm.; head length, 30 mm.; head 

 width, 31.4 mm.; femur, 37.5 mm.; tibia, 42 mm.; heel-to-toe, 60.8 

 mm.; hand, 29.5 mm. 



Color in alcohol. — Gunmetal blue on all exposed dorsal surfaces 

 except top of first two fingers and first three toes. A row of white 

 dots from posterior angle of jaw to above axilla, another row along 

 ulnar region. Small, scattered white dots along the side between the 

 dorsal ground color and the ventral ground color, which is cadaverish 

 gray. Anterior and posterior concealed surfaces of the thigh lavender. 

 A distinct, ocellus-like pectoral spot but no white spots below vent. 

 All-in-all a rather somber-looking Phyllomedusa. 



Remarks. — We are not satisfied with the present arrangement of 

 the species of somber-colored Phyllomedusa from western South 

 America. Few of these species have been seen in life by other than
