Diagnosis. — An Agalychnis with the first toe shorter than the 

 second, no dermal heel appendages, no pronounced glandular fold 

 above the vent although there is a glandular swelling, extensively 

 webbed fingers, and a sloping snout. It differs from all Colombian 

 phyllomedusids except A. calcarifer in the presence of extensively 

 webbed fingers. It differs from A. calcarifer in lacking the two promi- 

 nent triangular dermal heel appendages; in having distinct, clear 

 white, black-encircled, round spots scattered over the dorsum; in 

 having the palpebral membrane reticulate; in lacking the black, 

 finger-like projections from the dorsal ground color into the ventral 

 light surface; and in lacking any trace of pigment on the soles of the 

 hands and feet. 



Description.— BM 1913.11.12.129 [1947.2.24.24], (cotype), from 

 Pena Lisa, Condoto, Choc6, Colombia. Vomerine teeth in two small, 

 slightly elongate series, the outer ends more anterior so that together 

 they form a very broad broken \/ between the moderate-sized, squar- 

 ish choanae; tongue half as wide as mouth opening, elongated, its 

 posterior border extensively free and shallowly notched. Snout mod- 

 erate, broadly triangular when viewed from above, somewhat sloping 

 in profile, the upper jaw not extending beyond lower; nostrils more 

 lateral than superior, very slightly projecting, half again as far 

 from eye as from tip of upper lip, separated from each other by an 

 interval equal to about two- thirds their distance from eye. Canthus 

 rostralis slightly defined; loreal region somewhat concave and some- 

 what oblique, the upper lip flaring out slightly below it. Eye moderate, 

 not particularly prominent, its diameter equal to its distance from 

 nostrils; pupil vertical; interorbital distance half again as great as 

 width of upper eyelid, equal to distance between nostril and eye, 

 upper eyelid not particularly broad, equal to distance between nos- 

 trils. Tympanum very distinct, about three-fifths the diameter of 

 eye, and practically in contact with it. Fingers extensively webbed, 

 web reaching nearly to base of disk on lateral side of the fourth 

 finger, fourth considerably longer than second, reaching to middle
