Sorex montereyensis montereyensis ('. II. Merriam 

 Monterey Shrew 



Original description. — Sorex montereyensis .Merriam (1S95), p. 79. 



Type locality. — Monterey, Monterey County, California. 



Coloration. — In summer pelage, dull seal brown, in some specimens ap- 

 proaching sepia; in winter pelage sooty clove brown. Beneath but 

 slightly paler in either pelage and of same shade; fur at base slate- 

 black; tail sharply bicolor, seal brown above, dull white beneath; feet 

 (dried) drab; whiskers plumbeous. 



Cranium. — Large; braincase moderately inflated, though not conspicu- 

 ously arched. See figure 5 and table of cranial measurements. 



Measurements. — Fourteen specimens, from Monterey, Santa Clara, Ala- 

 meda, Marin and Mendocino counties, measure, average and extremes: 

 Total length 116.1mm. (111-126), tail vertebrae 51.5 (46-55), hind 

 foot 14.7 (13-16). Nineteen specimens from Humboldt County, 

 measure: Total length 125.8 (116-133), tail vertebrae 59.9 (54-65), 

 hind foot 14.7 (14-16). It looks as though there were a separately 

 recognizable race in the Humboldt Bay region, but lack of specimens 

 of the near-related^ Sorer trowbridgi i, from the coast district of 

 Oregon and Washington, prevents determination of this point at this 

 time.
