FROGS OF COLOMBIA — COCHRAN AND GOIN 223 



Diagnosis.- — A small "green" frog with greatly reduced webbing 

 between the fingers and with small patches of vomerine teeth. 



Hyla punctata may be distinguished from rubeola by having rounded 

 red spots (rather than tiny flecks of red) on the back and by its more 

 sturdy build. It may be distinguished from rhodoporus by having the 

 tympanum equal to about three-fifths (rather than two-thirds to 

 three-fourths) the diameter of eye and by the presence of rounded 

 red spots on the dorsum. 



Description. — UF 8518-1, from Leticia, Amazonas, Colombia. 

 Vomerine teeth in two short, rounded patches, lying close together 

 between the moderate-sized, rounded choanae; tongue two-thirds 

 as wide as mouth opening, broadly cordiform, its posterior border 

 slightly free and shallowly notched. Snout moderate, U-shaped when 

 viewed from above, truncate in profile, the upper jaw extending but 

 little beyond lower; nostrils more lateral than superior, somewhat 

 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 fairly well 

 defined; loreal region a little concave and somewhat oblique, the upper 

 lip flaring out moderately below it. Eye not large, but prominent, 

 its black choroid coat standing out sharply against the pale yellow 

 skin; its diameter equal to its distance from nostril; palpebral mem- 

 brane not reticulate; interorbital distance, upper eyelid, and distance 

 between nostrils about equal. Tympanum distinct, about three-fifths 

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

 half its own diameter. Fingers with but a trace of web at base, fourth 

 finger considerably longer than second, just reaching to disk of third 

 which covers about two-thirds the tympanic area; no projecting 

 rudiment of a pollex; a low ulnar ridge. Toes slightly less than one- 

 half webbed, the web on fourth toe reaching to middle of antepenul- 

 timate phalanx on the lateral side and to its base on the medial side, 

 third and fifth toes subequal, disk of fourth toe covering about one- 

 third the tympanic area; a distinct oval inner and a smaller, low, 

 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 ad- 

 pressed, heel reaches tip of snout; when limbs are laid along the side, 

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

 angles to body, heels do not quite meet. No patagium. Skin of upper 

 parts smooth; a rather narrow glandular ridge encircling upper 

 part of tympanum; skin of throat and chest very finely granular, 

 that of belly and lower surface of thigh uniformly and not so finely 

 granular; traces of a skinfold across chest; adult male, vocal sac not
