single species, Neotoma mexicana Baird, and the extraordinary opinion is expressed that N. albigula Hartley 'is not separable from N. mexicana. Here, as in a previous paper, the author shows himself hopelessly at sea. Neotoma albigula and N. mexicana not only inhabit different life zones but belong to different groups or subdivisions of the genus! The Arizona form of the Plains Prairie Dog is given as a distinct species, but anyone who will take the trouble to compare it with specimens from New Mexico and Texas will see that at most it is only a subspecies. On the other hand, the long-eared Arizona Jack Cottontail is given as a subspecies, though very distinct from any other known rabbit. By curious lapse of memory the round-tailed spermophile (Spermophilus tereticaudus) is allowed to remain in the subgenus Ictidomys-a subgenus erected by Dr. Allen in 1877 for species with narrow elongate skulls. The species originally referred to it are tereticaudus, tridecemlineatus andfranklini. S. tereticaudus has one of the shortest and broadest skulls known in the whole genus Spermophilus, but, probably by accidental transposition of skulls, it was described by Dr. Allen as long and slender. When his attention was called to the matter he very properly withdrew tereticaudus from the group and suiggested that 13-lineatus be taken as the type of Ictidomys, no type having been designated in the original description. But in the present paper the short skulled tereticaudus is again placed in Ictidomys! Say's ground squirrel (Spermophilus lateralis) is persistently referred to the genus Tamias-a genus with which it has no affinity whatever and to which it bears only the most superficial resemblance. With respect to the white-footed mice of the Peromyscus sonoriensis group, it is not likely that the last word has been said. The generic name Adelonycteris, adopted from Harrison Allen for the large Brown Bat, has no claim for recognition, being antedated by at least two names of equal pertinency. The specific name now in current use for the Mountain Sheep (Ovis canadensis Shaw) is replaced by 0. cervina Desm. without apparent reason. Both names were published in 1804, [N. S. VOL. II. No. 39.
