with pronounced lateral ridges, free, first finger much shorter than 

 second, fourth longer than either, and reaching to base of disk of 

 third which is about two-fifths the diameter of the eye; disks of the 

 three outer fingers large, disk of inner finger very small; a short oval 

 thumb pad present; a small bifurcate palmar callus; metacarpal 

 tubercles well developed. Toes fairly long, with a trace of web, third 

 toe much shorter than fifth, the disk of which reaches almost to base of 

 penultimate phalanx of fourth; disk of fourth toe equal in width to 

 that of third finger; a small but prominent inner metatarsal tubercle 

 and a very small, indistinct outer one; an indistinct tarsal ridge, 

 ending midway to heel; a series of skinfolds on heel and knee. Body 

 fairly stout, in postaxillary region a little narrower than greatest 

 width of head. When hind leg is adpressed, heel reaches a point 

 between eye and nostril; when limbs are laid along the sides, knee 

 and elbow touch; when hind legs are bent at right angles to body, 

 heels overlap. Skin of upper parts pustular, with a few small tubercles 

 above the shoulders and a single large tubercle on center of snout; 

 sides finely granular; venter granular posteriorly, chin and chest 

 nearly smooth; lower proximal surface of femur granular; a short 

 glandular ridge from posterior corner of eye curving over the depres- 

 sion in the tympanic area; a skinfold across chest; a ventral disk. 



Dimensions. — Head and body, 39 mm.; head length, 13 mm.; 

 head width, 14.5 mm.; femur, 18 mm.; tibia, 20 mm.; foot, 18 mm.; 

 hand, 12 mm. 



Color in alcohol. — Dorsum dull drab, with a round clove brown spot 

 on center of snout at base of median tubercle, and a wide, irregular 

 interorbital clove-brown bar, followed by an elongate median chevron 

 outlined with brown extending from above shoulders to sacrum; upper 

 limb surfaces olive with three clove brown diagonal crossbars outlined 

 with white (yellow?), sometimes enclosing another narrower dark 

 bar; side of body wood brown with several darker diagonal lines 

 crossing it; groin and proximal half of anterior femur tawny-olive 

 with heavy dark brown vermiculations; posterior femur drab with the 

 continuations of the bars across upper surface of femur; side of head 

 dull drab, with two dark spots from eye to upper lip, and a dark 

 stripe along canthus; venter wood brown, immaculate on beUy but 

 with irregular brown spots on chin fading out on chest; soles and 

 palms wood brown, tips of toes sepia. 



Remarks. — In the seven frogs at hand from the type locality, the 

 toes are webbed faintly and the adpressed heel reaches from a point 

 between the eye and the nostril to well beyond the snout. No true 

 tympanum appears in any of these specimens, although the depth of 

 the depression above the tympanic area varies from nearly plane with 

 the surrounding head region to a very perceptible indentation, but
