Remarks.—The ear measured from the notch is shortest, 19 (18-21), at Zamora, intermediate, 21 (19-23), at Pátzcuaro, and longest, 21.8 (20-23), at the type locality of gratus in the Valley of México.

Peromyscus banderanus banderanus Allen
Tarascan Mouse; Spanish, Ratón Tarasco
Peromyscus banderanus Allen, Bull. Amer. Mus. Nat. Hist., 9:51, March 15, 1897, type from Valle de Banderas, Nayarit; Osgood, Jour. Mamm., 26:300, November 14, 1945.
Peromyscus banderanus vicinior Osgood, N. Amer. Fauna, 28:209, 210, April 17, 1909, part.
Range.—Northern and eastern parts of state.
Remarks.—Specimens from Los Reyes referred to the subspecies P. b. vicinior by Osgood (1909:209-210) were later characterized by Osgood (1945:300) as agreeing with specimens from Zitácuaro, and Osgood (loc. cit.) thought that those from both Los Reyes and Zitácuaro were not P. b. vicinior but possibly P. b. banderanus. He had this material set aside for further study when he showed it to one of us (Hall) in 1945. It was his intention to revise the entire species (P. banderanus) but so far we know never did this before his death.
