pollex; toes slightly less than one-half webbed, third and fifth subequal, 

 disk of fourth toe covering one-third the tympanum; a distinct small 

 inner and a very minute outer metatarsal tubercle; a low glandular 

 ridge along inside of tarsus; no dermal appendage on heel. Body 

 very elongate, in the postaxillary region considerably less than 

 greatest diameter of head; when hind leg is adpressed, heel reaches 

 midway 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 greatly overlap. Skin of upper parts very smooth; a pronounced 

 glandular ridge encircling upper part of tj'^mpanum and ending on 

 shoulder; skin of chin smooth, of throat and chest very finely glandular, 

 of belly and lower femur very coarsely granular; no apparent skinfold 

 across the chest. A prominent external median vocal sac. 



Dimensions. — Head and body 26 mm.; head length 10 mm., width 

 8 mm.; femur 11.5 mm.; tibia 15 mm.; foot 10.5 mm.; hand 6 mm. 



Color in alcohol. — In the badly bleached and faded specimen de- 

 scribed, the following colors nevertheless can still be distinguished: 

 Ground color of upper parts pale wood brown; a russet stripe begin- 

 ning at the nostrils, continuing along the loreal region and through 

 the tympanum onto the sides where it fades out before reaching the 

 groin; a wide, pale dorsolateral stripe above this, beginning behind 

 the eyes and continuing to end of body; a wide russet stripe above this, 

 beginning on the upper eyelids and continuing back to the sacral 

 region; median dorsal region without markings, although the trans- 

 parency of the skin allows the dorsal aorta above the backbone to 

 be visible; entire ventral region, as well as upper and lower parts of 

 limbs, immaculate pale wood brown. 



Color in life. — From a sketch by Sandig of, presumably, USNM 

 96719. Top and side of head seal brown to vandyke brown, with the 

 brown continuing as a broad stripe down the center of the back, 

 becoming light russet before it reaches the anus, and edged with a 

 black stripe on each side; a very narrow black median line from tip 

 of snout to anus; a narrow v/hite line beginning at the nostrils and 

 running along the canthus rostralis, beginning again on the posterior 

 part of the eyelid and continuing to the groin; another black stripe 

 edging this white one from eye to groin on the sides; femur tawny to 

 ochre yellow with a suffusion of flesh color, without markings except 

 for a few dark dots near the knee; tibia also pinkish russet, with a 

 narrow dark fine along its outer border, then a stripe of the ground 

 color, then a wide upper area of fine black dots ; tarsus and forearm 

 wood brown, slightly spotted with darker; chin chrome yellow, chest 

 buff-pink, belly and sides sulphur yellow, lower surfaces of limbs buff- 

 pink, the hands and feet darker, the disks of the toes and fingers light. 

 Iris apparently light drab, the black pupil transversely eUiptic.
