Osgood (N. Amer. Fauna, 28:242, April 17, 1909) listed a specimen of this subspecies from Sierra Encarnación, Nuevo Leon. A specimen, No. 79614 BS, of this species was obtained on July 31, 1896, at Sierra Encarnación, Coahuila, by Nelson and Goldman. We know of no specimens of this subspecies from Sierra Encarnación, Nuevo Leon, and assume that Osgood referred to the Coahuilan specimen. Further support for this assumption is Osgood's (_loc. cit._) note that the Sierra Encarnación specimen is aberrant and, to our eye, so is No. 79614 from Coahuila.

Osgood (N. Amer. Fauna, 28:239, April 17, 1909) placed _P. merriami_ in synonymy under _Peromyscus eremicus eremicus_ (Baird). Because Seth B. Benson, and subsequently the late Wilfred H. Osgood, told one of us (Hall) that _Peromyscus merriami_ was specifically distinct from _Peromyscus eremicus eremicus_, we have examined the specimens from Sonoyta, Sonora, and Quitobaquita, Arizona, referred by Mearns (Bull. U. S. Nat. Mus., 56:434-435, and 444, April 13, 1907) to _P. e. eremicus_ and _P. merriami_, respectively. We perceive the differences that Mearns (_loc. cit._) described and recognize _P. merriami_ as a species separate from _P. eremicus_.

Also we have compared the type and one topotype of _Peromyscus goldmani_ Osgood with the holotype and referred specimens mentioned above, of _P. merriami_, and feel that the two kinds are no more than subspecifically distinct. Accordingly, _P. goldmani_ should stand as _Peromyscus merriami goldmani_. This arrangement is made with the knowledge that Burt (Misc. Publ. Mus. Zool., Univ. Michigan, 39:56, February 15, 1938) arranged _P. goldmani_ as a synonym of _Peromyscus eremicus_.

Osgood (N. Amer. Fauna, 28: 171, April 17, 1909) listed two specimens from Crooked River, 25 miles southeast of Prineville, Oregon, as _Peromyscus truei gilberti_ with the notation "approaching _truei_?" Subsequently, Bailey (N. Amer. Fauna, 55: 188, August 29, 1936) named _Peromyscus truei preblei_ with type locality at Crooked River, 20 miles southeast of Prineville, a place from which Bailey had two specimens. We think the specimens recorded by the two authors are the same, and, according to the specimen labels, were placed correctly as to locality by Bailey. Our reasons are as follows: (a) The specimens mentioned by Bailey were presumably available to Osgood, but Osgood made no mention of specimens from "20 miles southeast of Prineville," (b) we find no specimens nor other records pertaining thereto, of _Peromyscus truei_ from the locality given by Osgood, (c) Osgood indicated that the specimens he saw were not typical of _P. t. gilberti_ and (d) _P. m. gilberti_, geographically the nearest subspecies, is recorded otherwise no closer to Prineville than Grants Pass, approximately 175 miles southwest in southwestern Oregon.
