Skull, 23 by Cranial and dental characters.—The skull (fig. 95) is strongly depressed anteriorly, with the rostrum produced and the nasals pro- jecting. The zygomatic arches are incurved and convergent anteri- orly to meet the sloping zygomatic processes, this feature recalling the configuration of .young skulls of the other species of Peromyscas, in which the brain case has outgrown the face, though in this case We have the opposite condition, the facial portion being unusually elongated. In P. stephensi the profile of the skull is nearly straight above, declining to the front. The skull is remarkably narrow interorbitally. The teeth are shown in fig. 96. Remarks.—A specimen of this species in the American Museum collection (f|§| male adult, old) agrees in all respects with the type, and was collected at Palm Springs, San Diego County, California (Colorado Desert), February 19, 1893, by Mr. F. Stephens, for whom the species is named. "Total length, 181; tail vertebra' 110; hind foot, ; Peromyscus eremicus occurs with the present species at Palm Springs. Local distribution. The type was caught May 8, 1894, among granite bowlders at the first water in the canyon through which the Fig. 9fi.—Peromyscus ste- phensi.
