truncate at tip; angle of jaw below middle or posterior margin of 
orbit ; no vocal sac in evidence externally on male ; body heavy, slightly 
longer than wide, flat ; fore limb heavy, particularly in males ; about 
one-half of upper arm buried in skin of body; forearm stouter than 
upper arm in males, about equal in size in females ; hand about three- 
fourths length of forearm; two metacarpal tubercles, one in center 
of palm, second and smaller one on proximal side of first finger ; sub- 
articular tubercles numerous, a large one opposite end of first phalanx 
of each finger ; digits blunt-ended, subequal in length, in order of 
decreasing length, 3, 2, 1, 4, inner one stoutest, especially in males ; 
hind limb very stout; femur almost entirely buried in skin of body; 
tibia usually somewhat shorter than femur ; hind foot about two-thirds 
length of head-and-body ; tarsus comprising less than two-fifths length 
of foot ; two large blunt metatarsal tubercles, outer one rounded, inner 
with a free blunt end ; subarticular tubercles numerous and conspicu- 
ous; toes rather slender, in order of decreasing length, 4, 3, 5, 2, 1; 
web large for a toad, extending to tips of all toes, scalloped to middle 
of first (basal) phalanx on fourth toe. 
Tongue oval, broader behind, width about one-half that of jaws at 
angle of mouth, attached to floor of mouth for slightly more than half 
its length ; internal nares roundedly oval, placed far forward in mouth 
in females, slightly back from jaw in males. 
Tip of nose and margin of upper jaw smooth; upper surface of 
head, eyelids, dorsal surface of body and exposed surfaces of limbs 
with numerous blunt warts of varying size (up to 4 mm. in diameter) 
rounded or oval in outline ; between these, many fine pointed warts 
on females, few or none on males; lateral surface of body between 
limbs, abruptly areolar, divisions less than 2 mm. in diameter, a small 
raised point in center of each areola ; ventral surface of body and con- 
cealed surfaces of limbs smoothly areolate, with a fine point in center 
of each areola; plantar surfaces of feet wfith small warts, these more 
pointed on hind limb ; an enlarged wart often present on exposed 
surface of tibia. 
General ground color of exposed portions of body light green, 
yellowish green, or greenish brown ; brownish tinge lacking in males, 
at least during breeding season ; vertebral stripe 3 to 1 mm. in width, 
yellowish white ; dorsal warts dark brown, surrounded individually or 
in groups by broad areas of black ; little or no linear arrangement of 
warts or black areas; parotoid glands brown like dorsal warts; small 
warts on areolae of flanks, yellow or orange; ventral surfaces clay 
colored or dirty white, blotched irregularly with black in some indi- 
viduals, plain colored in others; exposed surfaces of hands and feet, 
dark gray ; larger tubercles on plantar surfaces yellowish brown ; 
nuptial excrescences on inner three fingers of males dark reddish 
brown (color description based on lot of twelve pairs of live adults 
collected near Oakland, April 16, 1912). 
Description of larva. — Greatest length of head-and-body 23 mm. ; 
of tail 33 mm. ; length of body contained about 1.5 times in length of 
tail; external nares nearer to orbit than to tip of snout; internarial 
width about 1.2 times in interorbital width; interorbital width 7 to 9 
in length of body ; orbit about 25 per cent of body length from tip of 
snout; spiraculum sinistra!, aperture directed backward and upward,
