another back of eye to the small parotoid. Snout short, rounded; 

 tongue about one-third as wide a mouth opening, oval, its posterior 

 border free and unnotched; snout truncate at tip when viewed from 

 above, projecting in profile, the upper jaw extending well beyond the 

 lower. Nostrils dorsal, strongly projecting, their distance from end of 

 snout one-half their distance from eye, with a subnasal ridge. Can thus 

 rostralis sharp, curved; loreal region concave, slanting outwards to 

 the upper lip. Eye large, prominent, its diameter 1% times its distance 

 from tip of snout; interorbital diameter 1% times that of upper eyelid, 

 much greater than interval between nostrils. Tympanum distinct, its 

 greatest diameter one-half that of eye, separated from eye by an 

 interval equal to about one-third its own diameter, but touching 

 postorbital crest. Fingers fairly long; with lateral ridges, faintly webbed 

 at base, first and second fingers subequal, fourth finger slightly longer 

 than either, reaching to base of penultimate phalanx of third; a small 

 oval thumb pad present; a large round palmar callus; metacarpal 

 tubercles well developed. Toes moderately long, one-half webbed, third 

 toe slightly longer than fifth, its disk reaching nearly to base of ante- 

 penultimate phalanx of fourth; a small oval inner metatarsal tubercle 

 and a smaller round outer one; no distinct tarsal ridge; a heavy 

 skinfold on heel and knee; soles granular. Body stout, in postaxillary 

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

 heel reaches just beyond axilla; when limbs are laid along the sides, 

 knee and elbow are slightly separated; when hind legs are bent at 

 right angles to body, heels overlap. Skin of upper parts tubercular, 

 the tubercles on top of head smaller and flatter; parotoid gland short, 

 slightly longer than eye, broadly triangular; venter finely granular, 

 with transverse folds across abdomen; a short coarse glandular ridge 

 from posterior corner of eye above tympanum, ending at parotoid; a 

 narrow crest curving inward from nostrils then outward to anterior 

 eye, encircling eye, continuing as a broad but weak posterior occipital 

 crest; another narrow crest bordering upper lip from eye to snout tip; 

 no skinfold across chest; no ventral disk; a median external vocal sac 

 in the male; first fingers of male are roughened in breeding season.

Color in alcohol. — Dorsum wood brown with large irregular clove

 outlined in clove brown; side of body wood brown with small dark 

 brown spots fading out below; venter light wood brown, immaculate 

 (in this specimen) except for a dark suffusion on the throat of the male;
