The young, when quite small, are slate-gray above, and grayish white below, with a black patch occupying the anterior third of the convex surface of the ear. Cranial and dental characters.—The skull and teeth of Peromyscus mearnsii (figs. 80 and 81) indicate a species allied to, but probably specifically distinct from, P. leucopus.

The young, when quite small, are slate-gray above, and grayish white below, with a black patch occupying the anterior third of the convex surface of the ear. Cranial and dental characters.—The skull and teeth of Peromyscus mearnsii (figs. 80 and 81) indicate a species allied to, but probably specifically distinct from, P. leucopus. The skullis smaller than that of P. texanus, from which it also differs in shape. Remarks.—This mouse differs from P. texanus, its next neighbor on the west, in being more scantily coated throughout, especially as to its tail, which is much longer than that of P. texanus, and differs further in not being sharply bicolor. In full winter pelage it is not so strikingly different, but the fur is shorter at all seasons. Fig 81.—Peromyscus mearnsii. Crowns (>l MoLAR TEETH, a, lower series; b, UP- PER SERIES.
