postaxillary region much less than greatest width of head. When hind 

 leg is adpressed, heel reaches beyond snout tip; when limbs are laid 

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

 bent at right angles to body, heels overlap. Skin of upper parts finely 

 granular, with a few short diagonal ridges on anterior part of back, 

 and some larger pustules [in original description, "smooth above 

 and below," but the type was a young frog measuring only 17 mm.]; 

 belly granular; throat and chest smooth; a small heel tubercle present; 

 a distinct glandular ridge from posterior corner of eye above tym- 

 panum, ending behind it; a skinfold across chest; a ventral disk 

 probably present, not very distinct in this specimen; a pair of external 

 lateral vocal sacs in the male. 



Dimensions. — Head and body, 28.5 mm.; head length, 11 mm.; 

 head width, 10 mm.; femur, 14 mm.; tibia, 16 mm.; foot, 12.5 mm.; 

 hand, 8.5 mm. 



Color in alcohol. — Dorsum cinnamon, the tops of the pustules a 

 little lighter; venter cream buff, with a network of very fine drab dots 

 that become concentrated into regular series of spots along the lower 

 lip border and also on the lower limb surfaces ; upper surface of femur 

 wood brown, with four regular russet crossbars continued on upper 

 parts of tibia and foot, and similar markings on forearm, posterior 

 femur wood brown, the light-topped granules making a pale network ; 

 anterior femur pale cinnamon, with anterior extensions of the russet 

 crossbands along the whole area. Side of body cream buff with indis- 

 tinct brown marblings. Side of head cream buff, loreal region russet; a 

 wide subocular russet spot, and a few smaller spots between eye and 

 nostril, usually reaching the edge of the upper lip. Soles of feet and 

 palms of hands buff with brown spots, the lower surface of the finger 

 disks dark brown, the fingers ringed with brown. 



Remarks. — In the original description, the adpressed heel of the type 

 was said to reach a point between the eye and the tip of the snout, but 

 in the frog just described it reaches somewhat beyond the snout. 



Some of the frogs from Huila, Meta, and Cauca have a wide, light 

 middorsal stripe and a sharp black tubercle above the shoulder; and 

 many show traces of dorsolateral skinfolds. They seem to resemble E. 

 cruentus, except that the digital disks are smaller, not covering the 

 tympanum. 



In two series of specimens (USNM 150780-95, 151024-5) from Finca 

 La Granja, Sierra de Santa Marta, Magdalena, that are presumed to 

 be E. calcaratus there are variations in pattern and structure. 



These specimens have the belly pale olive-buff to pale gray, with few 

 to many small drab to cinereus dots on throat and chest; in a few 

 examples the belly also is spotted; and one specimen has pale coral pink 

 suffusion on throat. The back is clove brown, drab or smoke gray, with
