palmar callus; metacarpal tubercles well developed. Toes slightly 

 webbed at base, long, with heavily fringed lateral ridges, third toe 

 longer than fifth, reaching beyond base of antepenultimate phalanx of 

 fourth; toes and fingers with small bulbous tips; a small but prominent 

 oval inner metatarsal tubercle and a small, indistinct, rounded outer 

 one; a heavy tarsal ridge, ending near heel; a heavy skinfold on heel 

 and knee. Body stout, in postaxillary region narrower than greatest 

 width of head. When hind leg is adpressed, heel reaches to tip of snout; 

 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 

 smooth; a narrow dorsolateral fold from posterior corner of eye, dimin- 

 ishing and soon disappearing on sacrum; venter smooth, except for 

 coarse granules on lower and posterior parts of femur; a heavy glan- 

 dular ridge from posterior corner of eye above tympanum, ending 

 above corner of mouth, a weak branch from this going backwards on 

 the sides and disappearing there; a skinfold across chest; a slight ven- 

 tral disk; no external vocal sacs in the male. 



Dimensions. — Head and body, 124 mm.; head length, 43 mm.; 

 head width, 51 mm.; femur, 56 mm.; tibia, 63 mm.; foot, 63.5 mm.; 

 hand, 31 mm. 



Color in alcohol. — Dorsum wood brown anteriorly to hazel pos- 

 teriorly, abroad sepia interocular bar edged with a narrow darker line, 

 and several irregular sepia crossbars on back also with dark outlines ; 

 a clove brown stripe beginning at tip of snout, continuing along 

 loreal region and on sides of body below dorsolateral lines; upper 

 leg surfaces clove brown, with scarcely a trace of crossbars; sides 

 of body sepia, lightening to drab ventrally; a clove brown line along 

 supratympanic ridge ending above shoulder; side of head drab to 

 drab gray, with three large burnt umber spots along lip borders, 

 the first and third spots extending vertically to nostril and eye re- 

 spectively; posterior femur drab above, to seal brown below, with 

 three or four rather small black bars crossing the lighter area, and 

 other black bars on concealed surface of tibia; venter raw umber 

 anteriorly to drab posteriorly with many small yellowish dots an- 

 teriorly, increasing in size to failry large round pale spots on pos- 

 terior belly and legs. 



Remarks. — The young of this form often are deceptively different 

 from the adult in pattern. Colors and design appear more brilliant 

 in 3- or 4-inch-long individuals. As in the other wide-ranging species, 

 further study of specimens from all parts of the range is needed 

 before definite recognition or suppression of some of the names now 

 synonymized can be decided upon. The currently accepted synonymy 

 has been given here, but a future monographer should compare 

 examples from each type locality before rendering a final decision.
