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 beginning
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.
Dimensions: Snout to vent, 47 mm.; width of head, 19 mm.; diameter
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
clove-brown interorbital bar; a sharply marked clove-brown streak
along the canthus rostralis from nostril to eye; lower canthai region
suffused with brown; a few brown bars on upper lip, a heavier one
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-
tinct brown cross bars; the upper posterior aspect of the femur with a
coarsely reticulate pattern of dark and light; lower part of liindleg
suffused with brown; a light stripe bordered by an irregular dark
stripe along the posterior tibia and outside of foot, and a similar dark
stripe along the arm and hand ; skin of lower parts of body immaculate
olive-buff.
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
;
