known maximum size of walesi (25 mm.) appears to be a little less 

 than that of the nominate form (27.5 mm.). 



The eight examples from Peligro on the Ramiriqui-Rondon road 

 have relatively longer legs than the other specimens, as the adpressed 

 heel reaches to the center or to the posterior or anterior corner of 

 the eye; in the other examples it extends from the anterior shoulder 

 insertion to the center of the tympanum, except in two individuals in 

 which it reaches the posterior corner of the eye. These eight specimens 

 are rather similar in color, although five have black throats (probably 

 a male characteristic) while the other three have light throats that are 

 more or less thickly black-spotted. Two of the five specimens from 

 Tunja show a dark suffusion on the chin. All other examples have 

 either an immaculate throat or a pale throat with scattered small 

 black spots. 



It is not feasible to give a separate name to the Peligro frogs at 

 this time. The collection and study of more extensive material may 

 serve to differentiate them positively. 



This form is named in honor of its collector, J. H. Wales.

Description. — MLS 309, a young adult from two kilometers south- 

 west of Fusagasuga, Cundinamarca, Colombia. Maxillary teeth present 

 but rather weakly developed; tongue half as wide as mouth opening, 

 ovate, its posterior border free, lobate, slightly notched in the center; 

 snout broadly obtuse when viewed from above, truncate in profile, 

 the upper jaw extending well beyond the lower. Nostrils lateral, 

 distinctly projecting, their distance from end of snout about one-third 

 their distance from eye. Can thus rostralis rounded; loreal region 

 nearly flat, descending vertically to the upper lip. Eye large, promi- 

 nent, its diameter nearly as great as its distance from tip of snout; 

 interorbital diameter IK times that of upper eyelid, equal to 

 interval between nostrils. Tympanum rather indistinct posteriorly, 

 its greatest diameter about one-third that of eye, separated from eye 

 by an interval equal to one- third its own diameter. Fingers moderate 

 in length, with lateral ridges, free, first finger shorter than second, 

 fourth longer than either, reaching to base of penultimate phalanx 

 of third, which covers about one-third the tympanum; a small oval 

 thumb pad present; a larger rounded palmar callus; metacarpal 

 tubercles well developed. Toes moderately long, one-half webbed, 

 third toe much longer than fifth, its disk reaching to center of ante-
