8<S NORTH AMERICAN FAUNA. [no. 10. 



Sorex montereyensis Meriiaui. Monterey Shrew. 



Six speciineiKs of this laijic long-tail slirew were secnre*! — one at the 

 lower edge of the lludsonian zone, near Mnd Creek; fonr in the Can- 

 adian zone, in ]\[nd Creek Canyon: and one in the Transition zone, in 

 S(|naw Creek A'alley, neai- AVanncastle Soda Sinnugs. 



Sorex (Neosorex) navigator Baird. Wliite-bellied AVater-shrew. 



Apparently rather searce. as a large auiouut of trapping resnlted iu 

 the captnre of only four specimens. These were obtained at as many 

 localities, namely, the head of Panther Creek, upi)er Squaw Creek, 

 upper Ash Creek Canyon, and Wagon Camp, all in the Canadian zone. 



Neurotrichus gibbsi major subsp. nov. Large Shrewmole. 



Type iroiii Carberry Rau<b, Shasta County, Calif, (alt. I,l(i0 ft., between Mts. Shasta 

 andliassen). No. 6r)321. ^^ ad., C S. Nat. Mus., Biological Survey Coll. Collected 

 .May IS, 1S!)4. hy C. 1'. Streator. Orig. No. 3789. 



VJmracters. — Similar to .V. (/ihh.si, but decidedly larger: hind feet 

 larger; forefeet much broader and longer; tail much longer; under 

 l)arts darker; skull larger and broader: ftfth upper lateral tooth (the 

 'large premolar') de(;idedly smaller than in X. (/ihh.si, and possessing a 

 distinct anterior cusp on the cingulum, which is absent in (jibh.si ; fifth 

 lower lateral tooth (the 'large premolar') decidedly larger than in (/ibbsi. 



Measurements. — Average of 3 specimens from type locality: Total 

 length, 120; tail vertebra*, -iO; hind foot, 17. Average of 4 specimens 

 from Mount Shasta: Total length, 113; tail vertebra-, 41; hind foot, 

 1().2. 



h'emarhs. — Four specimens of this new form of Gibbs shrewmole 

 were collected by our party on Shasta — all in the Canadian zone. 

 Three were caught in Mud Creek canyon near the mouth of Clear 

 Creek by Walter K. Fisher and W. H. Osgood, and one was taken at 

 Wagon Camp by ( )sgood. In ^lay, 1894, my assistant, Clark P. Streator, 

 obtained 3 specimens (the type and cotypes) at Carberry l{anch,on the 

 south side of Pitt Kiver, between Mounts Shasta and Lassen. Carberry 

 lianch is in the upper part of the Transition zone. The Canadian 

 zone specimens from Shasta are not cpiite so large, but agree in other 

 characters. 



Scapanus cahfornicus (Ayres). California Mole. 



Vernon Bailey found a dead mole of this species, October 3, iu the 

 road between Wagon Camp and Sisson at an altitude of 4,500 feet. 

 He reported mole ridges as common in ])laces a little ])elow Wagon 

 Camp, and also in sandy soil in the Murray pine belt east of the moun- 

 tain; W. II. Osgood saw mole ridges in Shasta Valley. 



Myotis evotis ( 1 1 . Allen.) Big-eared Hat. 



At Sisson, Seplember ;">, 11. T. I'ishcr olttained a si)ecimen from a 

 small boy, who caught it in a kitchen. The species doubtless occurs 

 in Shasta Vallev also.
