115); tail vertebrae, 44.3 (42-49); hind foot, 12.6 (12-13); 

 ear, 7.8 (7-9). 



Mr. Anderson states that the shrews were usually taken 

 "where there was a growth of moss and lichens in moist 

 places," or "in moist green spots near water," or "in groves 

 of firs and pines, when the moss-covered ground was always 

 damp." 



42. Sorex longicauda (Merriam). LONG-TAILED SHREW. 



Sorex obscurus longicaudata MERRIAM, N. Am. Fauna, No. 10, Dec. 

 31, 1895, 74. Wrangel, Alaska. 



Represented by 20 specimens (topotypes) from Fort Wran- 

 gel, taken June 25 to July 7, of which 2 are males and 18 

 females. The 2 adult males measure respectively: Total 

 length, 132, 137; tail vertebras, 56, 58; hind foot, 15, 16; ear, 

 8, 8. The ii adult females measure: Total length, 129 (122- 

 138); tail vertebrae, 56 (53-59); hind foot, 15.2 (14.5-16); 

 ear, 8 (7.5-8.5). The series is very uniform in coloration, 

 both above and below. 



Four of the six November specimens of Sorex from Ku- 

 preanof Island (near Wrangel Island), taken November 3,4, 

 and 8, are also referred to this subspecies. They differ, how- 

 ever, in color from the Wrangel June-July series in being 

 dusky plumbeous above, and in showing only a slight trace 

 of a buffy wash on the gray of the ventral surface. Two of 

 the specimens are moulting, apparently into the plumbeous 

 coat from the brown dress of the breeding season. 



This species differs from 5. obscurus in its considerably 

 larger size and more brownish coloration, particularly through 

 the brownish wash of the ventral surface. 



Mr. Anderson states that these specimens were ."usually 

 trapped under damp, overhanging mossy banks, or about the 

 roots of up-turned stumps." 



[Sorex richardsoni Bachman. SADDLE-BACKED SHREW. 



Three specimens of this species, not previously recorded, 

 were taken by Mr. A. J. Stone at Fort Norman, Mackenzie
