Not illustrated. 1897 Excerpt: . . . conforms very closely to the above description, and represents the opposite extreme from the red phase of M. musculus met with so frequently in the southwestern parts of the United States, as notably at several localities in Texas and Arizona. The striking feature is the generally dark coloration, and the broad black dorsal band occupying one-third to one-half of the whole dorsal area. A common inhabitant of old fields where it was associated with Rcithrodontomys mexicanus, R. rufescens, Peromyscus musculus brunneus, Oryzomys fulvescens, and Mierotus quasiater. 5. Reithrodontomys mexicanus De Saussure. --Represented by 14 specimens, ro males and 4 females, all adult, taken at Jalapa, March 29-April 14. They present the following measurements: Total Length. Tail Vertebra;. Hind Foot. Ear. IO! 161. 5(153-169) qo(8o-IOO) 18. 4(18-20) 15. 8(15-17) 4 9 8. . . . 160 (155-165) 87(85-88) 18. 5(18-19) 15. 7(14-17) In this species the tail is dull light brown above, and much lighter, grayish white below, being sharply and distinctly bicolor. The dorsal half is practically naked, while the ventral half is so well clothed with whitish hair. ; that the annulations are wholly concealed. The upper surface of the body is brown, rather darker medially as a rule, suffused to a slight extent with fulvous, passing gradually to a clear bright fulvous lateral band; the ventral surface is dull grayish white, with often a barely perceptible wash of pale buff, and an indistinct pectoral area of fulvous. A comparison of this large series of what is evidently true R. mexicanus with our R. mexicanus gracilis (anted, p. 9), from Yucatan, shows that the latter is specifically separable, and should stand as Reithrodontomys gracilis, characterized by its much smaller size, much paler and more yello. . .
