Vol. IX] TAYLOR— COOPER'S MAMMALS 83 



Specimen examined.— One : No. 629/1780, U. S. Nat. 

 Mus. ; original label lost ; A "N. Pac. R. R. Survey" label is 

 attached, the obverse of which reads "N. Pacific R. R. Survey, 

 Gov. . . Stevens 629/1780 Neosorex navigator Type Ft. 

 Vancouver, Columbia R., W. T. Dr. J. G. Cooper."; meas- 

 urements in pencil on the back of the label. 



Specimen in bad condition; for details see Lyon and Os- 

 good (1909, p. 246). 



Merriam has discussed the type locality of this form in the 

 following words : 



'Tt is evident that the type specimen, like many other alco- 

 holic mammals collected in the early days, was not labeled 

 until long after its capture, and that little dependence can be 

 placed on either of the alleged localities. Furthermore, since 

 the subgenus Neosorex is unknown from the Cascade region, 

 and probably does not inhabit western Oregon or Washing- 

 ton, which region is occupied by the allied subgenus Atophy- 

 rax, it is highly improbable that the specimen came from 

 either of the alleged localities. It agrees closely with speci- 

 mens from western Montana, and probably came from some 

 point in northern Idaho or the mountains east of Fort Col- 

 ville, in extreme northeastern Washington, which region was 

 visited by Dr. Cooper during the same expedition (1895, p. 

 92)." 



Several facts germane to this problem can now be cited as 

 tending to fix the type locality more definitely. Though 

 Neosorex pahtstris navigator has never been taken on the 

 humid coast belt in Washington, in which lies Fort Van- 

 couver, specimens have been secured by the Biological Survey 

 at the following localities in the Cascade Mountains : Signal 

 Peak (on the Yakima Indian Reservation east of Mt. 

 Adams), Mt. St. Helens, Mt. Adams, and Mt. Rainier. 



According to Cooper (1860b, p. 73), as quoted above, the 

 specimen under consideration (which became the type) was 

 "taken \yhile swimming under water in a lake near the sum- 

 mit of the Cascade mountains on August 31, 1853." But in 

 another place Cooper refers (1860a, p. 36) to the capture of 

 this animal, of which only one specimen was taken, on one 

 of the lakes at the head of the Yakima River. On August
