FROGS OF COLOMBIA — COCHRAN AND GOIN 365 



ing the choanae anteriorly; tongue half as wide as mouth opening, 

 broadly cordiform, its posterior border free and deeply notched; snout 

 blunt, broadly rounded when viewed from above, slanting forward to 

 upper lip in profile, upper jaw scarcely extending beyond lower. Nos- 

 trils dorsal, hardly projecting, their distance from end of snout twice 

 their distance from eye. Can thus rostralis very indistinct; loreal region 

 flat, sloping towards upper lip. Eye large, prominent, its diameter one- 

 half its distance from tip of snout; interorbital diameter slightly less 

 than that of upper eyelid, equal to interval between the nostrils; eye- 

 lid with a long single median spine, its length equal to one-fourth the 

 Avidth of eyelid. Tympanum fairly distinct, its greatest diameter three- 

 fifths the diameter of eye, spearated from eye by an interval slightly 

 greater than its own diameter. Fingers rather sort, with lateral ridges 

 and bulbous tips free, first finger longer than second, fourth equal to 

 first and both reaching to base of penultimate phalanx of third; a 

 broad, flattened thumb pad present; a wide palmar callus; metacarpal 

 tubercles well developed. Toes short, webbed at base, third toe longer 

 than fifth and reaching to base of antepenultimate phalanx of fourth; 

 a large, shovel-shaped inner metatarsal tubercle and a very small 

 round outer one; a heavy tarsal ridge ending near heel; a series of 

 weak skinfolds on heel and knee. Body very stout, in postaxillary 

 region equal to greatest width of head. When hind leg is adpressed, 

 heel reaches barely to axilla, and metatarsal tubercles to tympanum; 

 when limbs are laid along the sides, knee and elbow are widely 

 separated; when hind legs are bent at right angles to body, heels are 

 widely separated. Skin of upper parts granular, with many coarse 

 tubercles and ridges following the color pattern; throat and chest 

 with scattered granules; belly and lower femur with heavier granules; 

 a bony ridge from nostril to upper lip, and two from eye going 

 diagonally towards lip; a skinfold across chest; a ventral disk; 

 probably lateral external vocal sacs in the male. 



Dimensions. — Head and body, 71.5 mm.; head length, 32 mm.; head 

 width, 41.5 mm.; femur 25 mm.; tibia, 23.5 mm.; foot, 28.5 mm.; 

 hand, 19.5 mm. 



Color in alcohol. — Dorsum raw sienna, with three large oval clove 

 brown spots on either side of midline, and other more irregular 

 spots extending onto the sides, these set with many conical or elongate 

 tubercles; top of head mostly sepia, this color covering occiput and 

 extending in a broad, light-edged middorsal stripe almost to sacrum; 

 eyelids with two dark brown bars separated by the pale sienna ground 

 color, a small oval sienna patch on top of snout, with a brown elongate 

 gland in its center; upper leg surfaces with two wide sepia crossbars; 

 similar but smaller bars on forearm; venter immaculate pinkish buff; 

 anterior femur immaculate buff; posterior femur buff with a wide
