AMPHIBIANS AND REPTILES OF SINALOA, MEXICO 73
Eleutherodactylus hobartsmithi Taylor
EleutheTodactyhis hobartsmithi Taylor, Trans. Kansas Acad. Sci., 39:355,
April 3, 1936 (type locality, "Near Uruapan, Miohoac&n").
Remarks.—Ten males differ from the original description in having
the limbs distinctly barred with dark gray to black; the bars are
more conspicuous on the forelimbs. There is no dark line from
tip of snout to the eye, the tips of the digits are definitely widened,
and the typmanum is distinctly larger (1.7-2.2; mean 1.9) than the
eye (1.6-1.8; mean 1.7). In two specimens the testes are white
(captured 13 July 1960 and 12 July 1963); in the others the testes
are heavily pigmented with black.
In life, the back and legs are orange to orangish brown with an
inverted brown "V-shaped mark between the shoulders, and with
brown bands on the legs. The iris is a rose-gold, the belly yellow.
The dorsal coloration in life is pinkish gray according to Taylor
(1940c:501). Smith (1947:408) reported a frog of this species
from "near Aquiapan, Mexico" that possessed vestiges of vomerine
teeth. All the specimens examined by us lack any trace of vomerine
teeth. The tarsal tubercles are distinct. Reference of this species
to Eleuthewdactylus follows Lynch (1965:3).
Distribution in Sinaloa.—Known only from the southern highlands
near Santa Lucia. See Fig. 19.
Specimens examined,—2.4 mi. E Chupaderos (JFC 82:71); Santa Lucia,
1100 m. (°KU 75253-62); 4 mi. W Santa Lucia (JFC 62:4-13).
Additional records.—Santa Lucia, 1100 m. (KU 80324); Highway 40, 24.8
mi. E June. Hwy. 15 and 40 (Villa Union) (CAS 99313, 99315).
Eleutherodactylus occidentalis Taylor
Eleutherodactylus occidentalis Taylor, Proc. Biol. Soc. Washington, 54:91,
July 31,1941 (type locality, Hacienda El Florencio, Zacatecas).
Remarks.—A male (KU 78255) has a snout-vent length of 28 mm.,
white testicular membranes, first finger longer than second, vomerine
teeth, and an inner metatarsal tubercle strongly compressed and
cream-colored. This frog, and several others, probably of the same
species, called from a deep, dry, thickly wooded ravine during a
light rain on July 19. The frogs were clinging horizontally to small
twigs of bushes 0.3 to one meter above the ground. The call was
a single-note peep emitted at intervals of one to ten minutes.
Peters (1954:6) described the call for this species in Michoacan as
a piercing whistle of five or six single notes.
Another specimen, a juvenile, was active in wet grass at the edge
