=Peromyscus hylocetes= Merriam

Woods Mouse; Spanish, RatA cubedn Ocotero

Peromyscus hylocetes Merriam, Proc. Biol. Soc. Washington, 12:124, April 30, 1898, type from PAitzcuaro, 7,000 feet, MichoacAin; Osgood, N. Amer. Fauna, 28:159, pl. 3, fig. 8, April 17, 1909.

Range.--Mountainous parts of state.

Specimens examined, 24: nos. 100472, 100542, both from 9 mi. SE PAitzcuaro at 8,000 feet altitude; 1358-1365 of Bernardo Villa R., from Cerro CuritzarAin, 3.5 km. NNW San Juan, 2,200 M.; 52178, 52185, 52187-52192, 52197, 52198, 52203, 52213-52215, from TancA-taro at elevations of 6,000 to 10,000 ft.

Remarks.--All of the specimens were taken in pine forest. The old male from nine miles southeast of PAitzcuaro weighs 43.7 grams and the younger male from there 35 grams. The adults from TancA-taro have longer diastemae and some have the braincase more prolonged posteriorly, than in specimens from the vicinities of San Juan and PAitzcuaro but individual variation is considerable and we are unable to differentiate some of the adults from TancA-taro from those from elsewhere.
