palmar and plantar tubercles; no tarsal ridge or fold; the bent limbs 

 being pressed along the sides, the knee and elbow overlap; the hind- 

 limbs being adpressed, the heel reaches to between the eye and the 

 nostril ; the hind limbs being placed vertically to the axis of the body, 

 the heels considerably overlap; skin of upper parts fairly smooth, 

 with some scattered glandules on the back, especially concentrated on 

 the lumbar region and on the sides ; a faint dorsal ridge ; a heavy glan- 

 dular dorsolateral fold not extending forward beyond the level of the 

 axilla; a semicircular series of small glands over the ear and ending 

 below and behind it; a diagonal lateral series of elongate glands be- 

 ginning in front of the dorsolateral fold and extending downward 

 and backward on the side to about one-third the distance from axilla 

 to groin ; skin of throat and chest very faintly granular, of belly and 

 lower posterior aspect of thighs heavily granular, the remaining skin 

 of lower surfaces of legs and of arms being quite smooth ; an external 

 vocal sac (in the male) at the center of the throat, the loose skin 

 terminating in some transverse folds across the chest.

 eter of eye, 5.5 mm.; diameter of tympanum, 4.5 mm.; greatest width 

 of shovel on snout, 3 mm.; foreleg from axilla, 30 mm.; hindleg from 

 vent, 72 mm.; vent to heel, 44 mm. 



Color (in alcohol): Upper parts vinaceous-buff to olive-buff; a v/ide

 coming below the eye; a black crescentic mark above the ear, and a 

 similar crescentic mark paralleling it above the shoulders on the back ; 

 the dorsolateral fold and the short diagonal glandular lateral fold also 

 marked with clove-broAvn ; back covered with large, roundish, dark 

 spots, a pair of which are especially large and conspicuous on each side 

 of the back just anterior to the lumbar region; limbs with very dis-

Variations. — In our series of 19 frogs there are no young individuals; 

 hence I cannot say what variation occurs in the early periods. The 

 adults are very uniform in color pattern, although in some cases a 

 darker body color prevents the pattern from being so evident as in the 

 light clay-colored ones. The only noteworthy deviation from the 

 described specimen is in the amount of clouding of the ventral surface, 

 which in a few of the specimens, males probably, extends over the chin 

 and throat, to a lesser extent onto the bellj^ and very heavily on the
