Bull., 25:391, July 10, 1939 (type locality, kilometer 226, 20 miles northwest Tehuacan, Puebla). Eleutherodactylus augusti cactorum: Zweifel, Amer. Mus. Novitates, 1813:20, December 23, 1956. Remarks.—In eight specimens the diameter of tympanum is 2.7-4.3 (3.4) and greatest width of head 19.4-32.9 (24.8). The diameter of the typmamim averages 13.6 per cent of the width of the head. Dark purplish gray color dorsally (in preservative) is one of the diagnostic characters of this subspecies (Zweifel, 1956:20). Of the specimens examined, three collected in the summer of 1963 are purplish gray dorsally; those collected in 1955 and earlier are brown dorsally. All specimens examined by us agree with the description by Zweifel (1956:2-24). One individual was found in a mine shaft in a corn field, and two were in tropical deciduous forest less than 200 meters from a boulder-strewn stream inhabited by Hyla smaragdina and Syrrhophus modestus. A specimen (LACM 6201) was found on the road following a heavy rain on July 12, The road passes through a hilly area, suggesting that the frogs are inhabitants of rocky canyons and arroyos in the region north of Mazatlan. Distribution in Sinaloa.—Along the foothills of the Sierra Madre Occidental and in the canyons and arroyos in the southern part of the state. See Fig. 14. Specimens examined.—8.8 mi. N Ooyou'tan (LACM 6201); 41 mi. N Mazatlan (LACM 6202); San Ignacio, 210 m. (KU 73813); Santa Luck, 1100 m. (*KU 75238); 1 km. NE Santa Lucia, 1155 m. (*KU 78253); 2.2 km. NE Santa Lucia, 1155 m.

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
