sprinkling of tubercles. The > < shaped glands behind the head are 

 usually apparent; in one example (USNM 146965) the lower halves 

 of the chevrons are continued backwards as a heavily glandular dorso- 

 lateral line. 



The belly is very heavily granular and the throat is smooth in all 

 examples at hand. The heel may reach only to the posterior corner of 

 eye or to just beyond the snout. The toes usually have no webs, but 

 traces of webs are visible in one or two specimens.

Description. — MZUM 54486, an adult male from San Lorenzo, 

 Magdalena, Colombia. No bony ridges on top of head; frontoparietal 

 area somewhat sunken. Vomerine teeth in two short, heavy, transverse, 

 narrowly separated series behind the choanae; tongue large, three- 

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

 border free and notched; snout moderately rounded when viewed 

 from above and in profile, the upper jaw extending well beyond the 

 lower. Nostrils lateral, slightly projecting, their distance from end of 

 snout about one-half their distance from eye. Canthus rostralis 

 distinct; loreal region slightly concave, flaring outwards to the upper 

 Up. Eye large, prominent, its diameter four-fifths its distance from 

 end of snout; interorbital diameter equal to that of upper eyelid, a 

 little less than interval between nostrils. Tympanum small but 

 distinct, its greatest diameter one-fourth that of eye, separated from 

 eye by an interval equal to 1% times its own diameter. Fingers rather 

 short, with lateral ridges, free, first finger a little shorter than second, 

 fourth longer than either and reaching halfway on penultimate 

 phalanx of third, which covers three-fourths the tympanum; disks 

 of first and second fingers small; a crescentic oval thumb pad present; 

 a distinct semidivided palmar callus; metacarpal tubercles well 

 developed. Toes fairly long, very faintly webbed, third and fifth 

 subequal, their disks reaching to base of antepenultimate phalanx 

 of fourth toe; disk of fourth toe covering three-fourths the tympanum,
