FROGS OF COLOMBIA — COCHRAN AND GOIN 381 



Skin of upper parts slightly granular, with heavy glandular ridges 

 outlining a nearly square area behind eyes, across back above shoul- 

 ders, and between eyes; a glandular dorsolateral fold from posterior 

 eye nearly to level of groin; several short longitudinal glands on 

 posterior lumbar and sacral regions; venter smooth, except for some 

 transverse folds on posterior abdomen; a short heavy glandular ridge 

 from posterior corner of eye above tympanum, ending just behind it; 

 a heavy conical tubercle on lower jaw below commissure, and several 

 others above shoulder and along side of body; a skinfold across chest; 

 traces of a ventral disk; a pair of external lateral vocal sacs in the male. 



Dimensions. — Head and body, 52.5 mm.; head length, 20.5 mm.; 

 head width, 22 mm.; femur, 25.5 mm.; tibia, 27.5 mm.; foot, 22 mm.; 

 hand, 11.5 mm. 



Color in alcohol. — Top of head olive, back walnut brown, glandular 

 ridges outlined with clove brown and with a few indistinct diagonal 

 russet marks paralleling them; side of body olive-buff, with small 

 sepia vermiculations in front of groin; limbs wood brown above, the 

 femur with four or five wide sepia crossbars, a narrow dark bar between 

 each pair, the tibia, foot, and forearm with more-irregular dark bars; 

 posterior femur primrose yellow with heavy clove brown reticulations; 

 throat marbled with pale sepia and buff; belly immaculate pale buff; 

 side of head dull cream-buff with three or four wide sepia spots along 

 upper lip; palms of hands and soles of feet drab, the disks and tubercles 

 on toes a little lighter, the webs with small drab dots on a lighter 

 ground. 



Remarks. — It might seem that this frog belongs in Group I, in 

 which most members have the first finger longer than the second; 

 however, its lack of finger disks — in fact, its entire hand structure — 

 makes it truly "anomalous" among other species of that group. 



Three examples from Colombia agree very well with the type 

 except that the webs on their inner toes are a trifle longer, and in 

 one of these examples the adpressed heel does not extend beyond the 

 tip of the snout. The similarities, however, are much more striking 

 than these small differences, which would no doubt be bridged over 

 in a larger number of examples.
