FROGS OF COLOMBIA — COCHRAN AND GOIN 57 



Barbour (Barbour and Noble, 1920, p. 399) persuaded Boulenger that 

 pratti should be synonymized with latinasus, but a comparison of 

 Boulenger's material of the former with freshly collected specimens of 

 the latter shows that there is slight difference between the two. For 

 the present, it seems advisable to retain Boulenger's name.

Description. — USNM 150716, an adult from Montanita, Caldas, 

 Colombia. Tongue nearly two-thirds as wide as mouth opening, oval, 

 its posterior border free and unnotched; snout very broadly obtuse 

 when viewed from above, rounded in profile, the upper jaw extending 

 well beyond the lower. Nostrils lateral, slightly projecting, their 

 distance from end of snout one-fourth their distance from eye. Canthus 

 rostralis rounded; loreal region flat, vertical, flaring outwards to the 

 upper lip. Eye large, prominent, its diameter about four-fifths its 

 distance from tip of snout; interorbital diameter V/ 2 times that of 

 upper eyelid, narrower than interval between nostrils. Tympanum 

 distinct, its greatest diameter about half that of eye, separated from 

 e ye by an interval equal to one-fourth its own diameter. Fingers 

 long and slender, with lateral ridges, faintly webbed at the base, 

 first finger a little longer than second, fourth longer than either, 

 reaching to base of penultimate phalanx of third, the disk of which 

 covers about one-fourth the tympanum; a small oval thumb pad 

 present; a larger round palmar callus; metacarpal tubercles well 

 developed. Toes long, distinctly webbed at base, third toe longer 

 than fifth, its disk reaching to base of penultimate phalanx of fourth; 

 disk of fourth toe covering one-fourth the tympanum and equal to 

 that of third finger; a small oval inner metatarsal tubercle and a smaller 

 round outer one; a short, sharp tarsal ridge, ending diagonally halfway 

 to heel; a distinct skinfold on heel and knee. Body rather elongate, 

 in postaxillary region narrower than greatest width of head. When 

 hind leg is adpressed, heel reaches center of eye; when limbs are 

 laid along the sides, knee and elbow overlap; when hind legs are bent
