FROGS OF COLOMBIA — COCHRAN AND GOIN 425 



granular posteriorly and below anus, smooth on chin, chest, and an- 

 terior part of belly; a heavy glandular ridge from posterior corner of 

 eye about tympanum, ending above the shoulder; a slight skinfold 

 across the chest; traces of a ventral disk; probably a pair of lateral 

 external vocal sacs in the male. 



Dimensions. — Head and body, 54.5 mm.; head length, 18.5 mm.; 

 head width, 20 mm.; femur, 24.5 mm.; tibia, 26.5 mm.; foot, 25.5 mm.; 

 hand, 13.5 mm. 



Color in alcohol. — Dorsum seal brown, with a slightly darker X 

 covering the characteristic glands from inner posterior corner of eye 

 toward center of back, and ending at a level with the axilla; a pair of 

 indistinct dark spots on inner borders of upper eyelids; a black lateral 

 line beginning on tip of snout, bordering the canthus rostralis and con- 

 tinuing above and behind the tympanum to end just above shoulder; 

 upper surfaces of limbs with very faint dark crossbars; sides of body 

 cinnamon, with a fine clove brown network in axilla, nearly disappear- 

 ing on anterior half of side, then becoming thicker and darker with rela- 

 tively few light spots in front of groin and on anterior proximal part of 

 femur; posterior femur and belly clove brown with many minute light 

 dots; anterior distal femur and inside of tibia dark with light vertical 

 bars; venter wood brown with small gray dots thickly scattered on 

 chest and belly, less thickly on throat; edge of lower jaw with two or 

 three indistinct gray blotches; side of head seal brown, the area below 

 and behind nostril and in front of tympanum a little lighter; lower limb 

 surfaces dull wood brown heavily sprinkled with sepia dots; soles of 

 feet and palms of hands sepia, the disks and tubercles lighter. 



Remarks. — Because of its marbled side, dark-dotted throat, fairly 

 long legs, general proportions, and large size, this species suggests E. 

 w-nigrum, just as Dunn (1944a) suspected, although its usually granu- 

 lar underparts and slight frontoparietal depression indicate its alliance 

 with frogs of Group II. 



The adpressed heel reaches the anterior border of the eye in four of 

 the five examples at hand and to the nostril in the remaining one. The 

 belly may be smooth, or very faintly granular posteriorly. Above, the 

 five paratypes are nearly identical in pattern with the figure of the 

 type specimen given in Ruthven's original description. The smallest 

 frog has a much darker venter, the entire belly being clove brown with 

 some light spots; two larger specimens are nearly immaculate below, 

 the small dots occurrirg only at sides of chest, throat, and belly.
