at base, first and second completely webbed, first finger reduced, much 

 shorter than second, fourth longer than second, reaching halfway on 

 penultimate phalanx of third; fingers and toes with small swollen 

 disks scarcely under the phalanges; a small oval thumb pad present; 

 a larger round palmar callus; metarcarpal tubercles present. Toes 

 moderately long, third, fourth, and fifth almost completely webbed, 

 the others completely webbed; fifth toe longer than third, its disk 

 reaching to base of penultimate phalanx of fourth; a small flat, 

 rounded inner metatarsal tubercle and a slightly smaller round 

 outer one; a weak tarsal ridge, ending midway to heel; a skinfold on 

 heel and knee. Body elongate, in postaxillary region equal to greatest 

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

 eye; when arm is adpressed, fingers extend behind body by at least 

 the two terminal phalanges of third finger; when limbs are laid along 

 the sides, knee and elbow overlap; when hind legs are bent at right 

 angles to body, heels touch. Skin of upper parts smooth, pustular 

 under the lens, the pustules becoming small granules on sides of 

 head and body and on sacrum; venter weakly granular posteriorly, 

 with many fine transverse and logitudinal wrinkles anteriorly; a 

 wide, rather weak glandular ridge from posterior corner of eye above 

 tympanic area, ending above shoulder insertion; suggestions of a 

 skinfold across the chest; no ventral disk; no external vocal sacs or 

 thickened forearm in the male, but a smooth brown callosity on inner 

 surface of first finger. 



Dimensions. — Head and body, 38 mm.; head length, 10 mm.; 

 head width, 10 mm.; femur, 16.5 mm.; tibia, 18 mm.; foot, 14.5 mm.; 

 hand, 12 mm. 



Color in alcohol. — Dorsum, sides of body, and upper limb surfaces 

 wood brown with a coarse but regular sepia vermiculation which is 

 concentrated into an irregular, broken dorsolateral stripe beginning 

 at tip of snout, continuing below canthus, above tympanic area and 

 along side of body to groin; rest of side of head olive buff, the anterior 

 and posterior region of the eye sepia; irregular sepia ocelli on anterior 

 and posterior limb surfaces; venter light clay color, the throat, chin 

 and anterior half of belly immaculate, and a few small irregular sepia 

 ocellated spots on its posterior half; palms of hands and soles of feet 

 raw sienna, immaculate. 



Remarks. — The large series of 26 paratypes shows remarkable 

 uniformity in color pattern. Many lack the small dark spots on the 

 belly, and some have a wide wood brown area above the dark dorso- 

 lateral stripe. The largest example is 43.5 millimeters in total length. 

 The adpressed heel reaches to the center or anterior corner of the eye 

 in most examples, although it may come only to the angle of the jaw
