border; snout short, ending in a pointed dermal appendage, appearing 

 concave in profile because of this appendage; upper jaw projecting 

 considerably beyond lower because of the appendage; nostrils supe- 

 rior, at the intersection of the very sharp canthus rostralis and an 

 oblique loreal ridge, separated from each other by an interval equal to 

 two-thirds their distance from eye. Canthus rostralis raised, curved 

 and sharp, the area between the canthi very concave; a lesser ridge 

 crosses this area between the anterior corners of the eyelids; loreal 

 region sloping obliquely and slightly concave except for the heavy 

 diagonal ridge originating just below the eye and ending at the nostril. 

 Eye large and prominent, but appearing less so because of the upper 

 eyelid which is elongated into a very long dermal horn; diameter of 

 eye equal to its distance from nostril. A heavy ridge continued back- 

 ward from each canthus and over the occipital region, the distance 

 between the crests in the interorbital region about four-fifths the 

 width of upper ej^elid plus horn. Tympanum barely visible, its dis- 

 tance from eye apparently equal to its own diameter. Fingers slightly 

 webbed at the base, with heavy dermal ridges along their sides, their 

 tips not dilated, first a little shorter than second which is equal to 

 fourth; a pronounced shovellike tubercle on base of first finger; all 

 subarticular tubercles well developed; a fairly distinct axillar wing 

 terminating the loose lateral folds of skin ; toes one-third webbed, not 

 dilated, with serrate dermal ridges along their sides, third longer than 

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

 medium-sized shovellike inner metatarsal tubercle but no outer one; 

 a heavy fringed dermal ridge of triangular points along outer side of 

 tarsus to heel, continued as a prolongation of the ridge on outside of 

 fifth toe; another inner tarsal ridge, similar but shorter, curving around 

 the base of the shovellike tubercle. Body stout, in postaxillary region 

 narrower than the very wide head; when hind leg is adpressed, heel 

 reaches to posterior corner of eye; when limbs are laid along the body, 

 knee and elbow touch; when hind legs are bent at right angles to the 

 body, heels just fail to touch. Skin of central dorsal area fairly 

 smooth except for two rows of warts paralleling the very conspicuous 

 sinuous ridges emanating from the border of the eyelid, continuing 

 over the tympanic area, nearly converging at the center of the back, 

 diverging over the sacrum and meeting above the anus; several diag- 

 onal rows of granules, elongate glands, and triangular lobes on the sides 

 of the body from the corner of the mouth to the groin; a very pro- 

 nounced ridge of triangular lobes along outside of forearm, and other 

 similar rows crossing top of tibia diagonally; venter finely granular 

 everywhere, except for a few coarser granules below the anus. Traces 

 of a skinfold across the throat, indicating a probable internal vocal 

 sac.
