Aguililla; Apatzingan (8); Cascada Tzararacua: Charapendo
(5); Coalcoman (5); 18 km. E of Dos Aguas (6); El Sabino
(5); La Playa (2); Jiquilpan; Uruapan (2); Volcan Jorullo;
Zamora.

In life, specimens from Apatzingan (UMMZ 114308-9) varied in dorsal
color from grayish tan to pale brown; the dorsal markings were olive
green. The thighs and groin were yellowish orange; the iris was pale
golden, and the vocal sac was purplish gray (Pl. 5, Fig. 1).
Measurements for 13 adult males from the Tepalcatepec Valley are:
snout-vent length, 21.9-26.8 (24.3); tibia length, 8.4-9.9 (9.3); head
width, 7.2-9.2 (7.8); head length, 7.6-8.7 (8.2).

At Apatzingan and Charapendo in the Tepalcatepec Valley males were found
calling from rocks and bushes in open arid tropical scrub forest. The
call, a triple note "peep-ee-eep," is repeated once every 90 to 135
seconds. _Tomodactylus nitidus petersi_ probably ranges throughout the
Tepalcatepec Valley and surrounding foothills. Dixon (1957:392) referred
the specimens from Zamora, Jiquilpan, and Uruapan to this subspecies.
Uruapan is near the lower limits of the pine forest on the slopes of the
Cordillera Volcanica; Zamora and Jiquilpan are on a low part of the
Mexican Plateau southeast of Lago de Chapala.

_Tomodactylus rufescens_ Duellman and Dixon, Texas Jour.
Sci., 11:78, March, 1959.--Dos Aguas, Michoacan, Mexico.

Dos Aguas (14); 18 km. E of Dos Aguas (6).

Fourteen specimens from the pine-oak forests around Dos Aguas (UMMZ
118503-10, 121498-9) have reddish brown dorsal color and a narrow
cream-colored middorsal line (Pl. 5, Fig. 2). Twelve of these specimens
are adult males having snout-vent lengths of 20.7 to 24.6 (22.5) mm. One
female has a snout-vent length of 24.8 mm., and one juvenile has a
snout-vent length of 14.5 mm. Six specimens are from a region of mixture
of pine-oak forest and arid tropical scrub forest at 18 kilometers east
of Dos Aguas (UMMZ 121497, 121500). All are males having snout-vent
lengths of 18.0 to 22.6 (20.7) mm. The dorsum is tan marked with black;
the thighs are yello
