~Rana montezumae~ Baird

_Rana montezumae_ Baird, Proc. Acad. Nat. Sci. Philadelphia,
7:61, October 20, 1854.--Mexico City, Distrito Federal,
Mexico.

La Palma; 8 km. NW of Maravatio (10); Sahuayo; Tupataro (7).

This species probably is more abundant and widespread than is indicated
by the few specimens listed above. It has been found only in the
vicinity of permanent water on the Mexican Plateau and the mountains
rising from the plateau at elevations of 1500 to 2000 meters. Its
apparent absence from Lago de Patzcuaro cannot be explained, unless
_Rana dunni_ replaces it there.

~Rana pipiens~ Schreber

Camachines (2); Capirio; Cascada Tzararacua (3); Cerro San
Andres (6); Charapendo (4); Ciudad Hidalgo; Coalcoman (17);
Cuitzeo (3); El Sabino (10); Jacona (3); 29 km. NW of Jacona
(8); Jiquilpan; La Orilla (3); La Palma (5); La Playa (4);
Lago de Chapala (3); Lago de Patzcuaro (6); Lombardia; Los
Conejos (67); Los Reyes (7); Macho de Agua; Maravatio;
Morelia (5); Opopeo (3); Patzcuaro (9); 26 km. S of
Patzcuaro (52); Puerto Hondo (3); Rio Duero, 14 km. E of
Zamora (13); Rio Tepalcatepec, 27 km. S of Apatzingan (2);
San Gregorio (38); San Jose de la Cumbre (5); Tangamandapio;
Zacapu; 18 km. W of Zamora (35).

Except on the Pacific lowlands, this species is abundant throughout the
state. It has been collected from sea level to 2800 meters, the greatest
altitudinal range of any amphibian in Michoacan. It has been found
frequently in the Tepalcatepec Valley; it is not a distinctly highland
species in southern Michoacan, as stated by Peters (1954:9). One
specimen from Aguililla (UMMZ 119257) is an albino. In this specimen
there is a faint pattern on the hind limbs; otherwise the entire body is
creamy white; the eyes are pink.

~Rana pustulosa~ Boulenger

_Rana pustulosa_ Boulenger, Ann. Mag. Nat. Hist., ser. 5,
11:343, 1883.--Ventanas, Durango, Mexico.

Arteaga (4); 21 km. S of Arteaga; Cascada Tzararacua (3);
Coalcoman (3); 12 km. ENE of Dos Aguas (3); El Sabino (53);
Los Reyes (3); Tzitzio (4); Uruapan.

Although _Rana pustulosa_ seems to be absent from the Mexican Plateau in
Michoacan, it has been collected at elevations
