Description. — Three specimens in the Y . S. National Museum col- 

 lection (Nos. kfffi Bfflh and HW) 3 from the San Pedro Martir 

 Mountains, Lower Califor- 

 nia, collected by Mr. Charles 

 II. Townsend, in April and 

 May. L889, have the pelage 

 short and coarse, and are dis- 

 tinctly paler and more hoary 

 than S. hudsonicus calif or- 

 nicus from central Califor- 

 nia. The April specimen 

 (No. 18205. female adult) 

 has the reddish vertebral 

 stripe tolerably distinct, 

 with yellowish on nape and 

 reddish on rump; but in the 

 two" May specimens, proba- 

 bly males, though the sex is 

 not indicated, this is less dis- 

 tinct, the color being pepper- 

 and - salt. suffused with 

 tawny ochraceous above. In 

 all three specimens the black 

 stripe at the side is strongly 

 marked, as much so as in the 

 subspecies calif omiciis. The 

 ears are heavily tufted with 

 black. The under parts are 

 white, with plumbeous at base. Feet yellowish white. All three 

 are in winter coat, but molting had begun in No. L8267 and pro- 

 ceeded irregularly over most of the fore limbs. On the mane the 

 new hairs are strongly yellowish instead of soiled white; not molt- 

 ing on hind feet. The tail is short and comparatively short-haired;
