_Comparisons._--Skull larger than that of _S. v. obscurus_ and relatively somewhat broader; much larger in all cranial dimensions than _S. v. monticola_. _Remarks._--_S. v. neomexicanus_ is a well-marked subspecies seemingly limited to the mountains of southeastern New Mexico. It is the only species of _Sorex_ thus far recorded from that area. _Specimens examined._--Total number, 12. NEW MEXICO: _Otero Co._: SW slope Capitan Mts., 2 BS; 10 mi. NE Cloudcroft, 2 BS; Cloudcroft, 7 BS, 1 UM. _Marginal records._--NEW MEXICO: SW slope Capitan Mts.; 10 mi. NE Cloudcroft; type locality. =Sorex vagrans monticola= Merriam _Sorex monticolus_ Merriam, N. Amer. Fauna, 3:43, September 11, 1890. _Sorex vagrans monticola_, Merriam, N. Amer. Fauna, 10:69, December 31, 1895. _Sorex melanogenys_ Hall, Jour. Mamm., 13:260, August 9, 1932, type from Marijilda Canyon, 8600 ft., Graham Mts. [= Pinaleno Mts.] Graham Co., Arizona. _Type._--Adult male, skin and skull; No. 17599/24535, U. S. Biol. Surv. Coll.; obtained on August 28, 1899, by C. Hart Merriam and Vernon Bailey from San Francisco Mtn., 11,500 ft., Coconino Co., Arizona. _Range._--Mountains of western New Mexico, eastern Arizona, and the northern Sierra Madre Occidental of Mexico. _Diagnosis._--Size small for the species; average and extreme measurements of 12 specimens from the White Mountains, Arizona, are: total length, 104.3 (98-112); tail, 41.2 (37-45); hind foot, 12.0 (11-13). Summer pelage between (15'_m_) Proutts Brown and (15''_m_) Bister, venter tinged with (15'_f_) Pale Ochraceous Buff; winter pelage near (17'''_k_) Olive Brown; skull relatively broad. _Comparisons._--For comparisons with _S. v. obscurus_ and _S. v. neomexicanus_ see accounts of those subspecies. Skull slightly larger and relatively broader than that of _S. v. orizabae_, and color slightly paler. Differs from _S. v. vagrans_ in: winter pelage grayish (near 17'''_k_ Olive Brown) rather than blackish (17''''_k_ or 17''''_m_ Chaetura Drab or Chaetura Black); summer pelage slightly grayer; skull relatively slightly broader rostrally and interorbitally.
