winter coat. The two August specimens, both apparently 

 females, are very much darker. 



A female from Homer, collected by the Stone Expedition 

 in 1901, and formerly identified (this Bullet n, XVI, 1902, 

 p. 228) as P. arcticus kadiacensis , is to be referred here. 



The four males measure, total length, 334 (312346); tail 

 vertebrae, 92 (89-94); hind foot, 46 (43-49); ear, 22 (21-23). 

 Two females, 270 (260-280), 71.5 (70-73), 35.5 (34-37). l8

25. Mustela americana Turton. AMERICAN MARTIN. Two 

 skulls, Seldovia. These skulls greatly exceed in size the very 

 largest skulls of a large series of M. americana from New 

 Brunswick, but fall considerably short of the measurements 

 given by Mr. Osgood for the type skull of M. a. actuosa. 



26. Sorex personatus /. Geoffroy. COMMON SHREW. One 

 hundred and eighty-six specimens, collected as follows: Muller 

 Bay, 4, June 1-7; Seldovia, 97, June 2 6- August 2; Barabori, 

 9, August 6 and 28-Sept. i; Sheep Creek, 35, August 13-26; 

 Carbou Camp, 14, Sept. 3-9; Moose Camp, 27, Sept. 25- 

 Oct. 6. 



At Muller Bay ' 'shrews were quite scarce," but on Kenai 

 Peninsula this species was apparently everywhere abundant. 



27. Sorex obscurus alascensis Merriam. ALASKA SHREW. 

 Thirty-seven specimens: Seldovia, 26, June 26-August 3; 

 Barabori, i, Sept. i; Caribou Camp, 7, Sept. 3-9; Sheep 

 Creek, 3, Sept. 12-14. 



Evidently less abundant than the preceding, but widely 

 dispersed, though apparently not met with at Moose Camp, 

 where 5. personatus was very abundant. 



28. Sorex eximius Osgood. OSGOOD'S SHREW. Two speci- 

 mens, Barabori, Sept. 9, and Moose Camp, Oct. i. 



This species, previously known only from the type, taken 

 at Tyonek, Cook Inlet, Alaska, Sept. 14, 1900, by Osgood and 

 Heller, is evidently either not numerous or very hard to cap- 

 ture, as of 225 Shrews taken by Mr. Anderson only two were 

 of this species.
