considerably beyond lower. Nostrils superolateral, not projecting, 

 their distance from end of snout slightly less than their distance from 

 eye, separated from each other by an mterval equal to their distance 

 from tip of snout. Canthus rostralis distinct; the loreal region slop- 

 ing very gradually, concave, merging with the flaring upper lip. Eye 

 large, prominent, its diameter equal to three-fourths its distance 

 from end of snout; interorbital diameter about four-fifths the width 

 of upper ej^elid, a little less than distance between nostr'Js. Tympa- 

 nmn large, distinct, three-fourths the diameter of eye, separated from 

 eye by an interval equal to one-half its own diameter. Fingers free, 

 with distinct lateral ridges, fourth finger longer than second, reaching 

 to base of antepenultimate phalanx of second, first longer than fourth, 

 reaching almost to base of last phalanx of third ; two heavy tubercles 

 on thumb, one at base and one halfway to tip of first finger, each 

 equipped with a black spur in the breeding season; subarticular and 

 palmar tubercles well developed. Toes webbed at the base, with 

 distinct lateral ridges, third longer than fifth, reaching halfway on 

 antepenultimate phalanx of fourth; a small conical inner and a miuute 

 flattened outer metatarsal tubercle; a heavy glandular ridge on tarsus 

 from inner tubercle to heel. Body stout, in postaxillary region nearly 

 equal to the head width; when hind leg is adpressed, heel reaches to 

 anterior eye; when limbs are laid along the sides, knee and elbow 

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

 considerably overlap. Skin of head smooth, back with five pairs of 

 longitudinal folds, the outer pair emanating from the eye, margining 

 the upper tympanum and continuing to the groin; the next pair 

 dorsolateral in position, less distinct anteriorly and ending in a series 

 of short glands behind the sacrum ; the next two pairs edging the Hght 

 stripe which leaves the upper eyelid and continues down the back to 

 the base of the legs; the inmost pair short, not distinct anteriorly or 

 posteriorly, lying on each side of the vertebral lines; some scattered, 

 short conical glands on sides, occiput and top of femur; no definite 

 gland in groin or behind commissure of mouth; posterior surface of 

 femur with granules and many small ridged glands which extend 

 across the lower part of femur; a distinct ventral disk; a fold on each 

 side of neck in front of shoulder indicates the presence of internal 

 vocal sacs. 



Dimensions. — Head and body 76 mm. ; head length 26 mm., width 26 

 mm. ; femur 32 mm. ; tibia 36 mm. ; foot 38 mm. ; hand 17 mm. 



Color in alcohol. — Dorsum slate-gray, with a large heart-shaped 

 black spot between the eyes and extending backwards almost to base 

 of occiput; a wide black band commencing at end of snout, covering 

 the canthus and ending on anterior eyelid; behind the eye a series of
