Lynx ruffus escuinapae Allen, Bull. Amer. Mus. Nat. Hist., 19:614, November 14, 1903, type from Escuinapa, Sinaloa.
Range.—Probably all of state above the Tropical Life-zone.
Specimen examined, 1: no. 47818 (U. S. Nat. Mus., Biol. Surv. Coll.), Pátzcuaro.
Remarks.—The skull of the male from Pátzcuaro agrees well with those of topotypes of L. r. escuinapae even to the elongate tympanic bullae. Because of their elongation the bullae resemble, in some degree, those of the ocelot. Natives told us that the gato del monte was resident around Pátzcuaro. Four miles south of Pátzcuaro in a cornfield at the edge of an area grown up to oak trees and brush, tracks were seen that our Indian companion identified as those of the gato del monte.
Citellus variegatus variegatus (Erxleben)
Rock Squirrel; Spanish, Ardilla de Pedregal; Tarascan, Kuaráki (Kuaraki)
[Sciurus] variegatus Erxleben, Syst. Regni, Anim., 1:421, 1777; type locality fixed as Valley of México near the city of México, by Nelson, Science, N. S., 8:898, December 23, 1898.
[Citellus] variegatus, Elliot, Field Columb. Mus. Pub., zoöl. ser. 4:148, 1904.
Range.—Probably in all semi-arid, rocky habitats of the state.
Specimens examined, 11: nos. 100128-100135; 51385-51387, distributed by localities as follows: 1 mi. N Zamora, 5,450 ft., 1; 3 mi. NW Pátzcuaro, 6,700 ft., 5; 4 mi. S Pátzcuaro, 7,800 ft., 1; 1-½ mi. S Tacámbaro, 5,700 ft., 1; Mount Tancítaro, 1; Pedregal, Tancítaro, 1; Tancítaro, 1.
Remarks.—Rock squirrels were seen along rock fences, around Pátzcuaro, where they are fairly common. On July 17 and 18, 1947, at San Juan Parangaricutiro, one of us (Villa) saw these squirrels running over the newly formed lava bed which was still emitting vapors and which in places (between boulders) was emitting heat detectable by the collectors. This is only additional evidence of the animal's strong predilection for rocks, boulders and cliffs, which has earned for it, in parts of the western United States, the vernacular name "rock squirrel" and in México "Ardilla de Pedregal."
