FROGS OF COLOMBIA — COCHRAN AND GOIN 93 



to fourth, which reaches to base of penultimate phalanx of third; 

 an oval projecting thumb pad present; a small rounded palmar 

 callus; metacarpal tubercles well developed. Toes without disks, 

 webbed at the base, third toe a trifle longer than fifth, its tip reaching 

 to base of antepenultimate phalanx of fourth; a small, pointed 

 metatarsal tubercle and a smaller round outer one; a distinct outer 

 tarsal ridge edged with small tubercles, ending at heel, and a similar 

 but smaller inner one; a pronounced skinfold on heel and knee; 

 soles granular. Body short and stout, in postaxillary region equal 

 to greatest width of head. When hind leg is adpressed, heel reaches 

 posterior corner of eye; when limbs are laid along the sides, knee 

 and elbow slightly overlap; when hind legs are bent at right angles 

 to body, heels touch. Skin of upper parts with minute tubercles and 

 granules, enlarged along middorsal line, on top of head, and on sacrum; 

 a heavy lateral fold beginning at posterior corner of eye, widening 

 to an elongate parotoid gland, and becoming narrower but still quite 

 distinct and set with tubercles from axilla to groin; throat and chest 

 faintly granular; belly and lower proximal femur distinctly but finely 

 granular; no glandular ridge from posterior corner of eye above 

 tympanum, its place being taken by the parotoid and lateral tubercles; 

 a slight skinfold across the chest; no ventral disk; no external vocal 

 sacs. 



Dimensions. — Head and body, 23 mm.; head length, 8 mm.; head 

 width, 8 mm.; femur, 10 mm.; tibia, 10.5 mm.; foot, 8.5 mm.; hand, 

 6.5 mm. 



Remarks. — Upon direct comparison, MLS 50 and the type (BM 

 80.12.5.151) are certainly conspecific. The type is larger (35 mm.) 

 and now somewhat softer, but otherwise the two specimens are very 

 similar. Even the dorsal pattern is strikingly similar in the two speci- 

 mens, although in the type it is somewhat more faded than in the 

 fresher Colombian specimen. The bony ridge on the inner and posterior 

 sides of the orbit is more pronounced in the type, but this most likely 

 is due to its greater age. The parotoid glands on the type are more 

 conspicuous, but this also probably is due to age. The bandings on 

 the arms and legs of the two specimens are essentially identical.
