GENERAL ACCOUNTS OF THE MAMMALS 

 Sorex personatus personatus I. Geoffrey. Masked Shrew 

 Obtained only in the vicinity of Telegraph Creek and at Great 

 Glacier. Seven taken at Telegraph Creek and five at the nearby station 

 of the Junction (nos. 30527, 30535, 30554-30559, 30561, 31052-31054). 

 Seven specimens from Great Glacier (nos. 30544, 30562-30567), though 

 referred to Sorex personatus personatus, show intergradation toward 

 S. p. streatori. These determinations, as well as those of the other 

 forms of Sorex and Microsorex here treated, were made by Dr. Hartley 

 H. T. Jackson, of the United States Biological Survey. 



Sorex obscurus obscurus Merriam. Dusky Shrew 

 Seven specimens taken at the Junction, five at Telegraph Creek, 

 three at Glenora, tw;o at Doch-da-on Creek, and one at Flood Glacier 

 (nos. 30522-30526, 30528-30534, 30536-30541 ) . Shrews were nowhere 

 abundant. 



Sorex obscurus longicauda Merriam. Long-tailed Shrew 

 Ten from Great Glacier and two from Sergief Island (nos. 30542, 

 30543, 30545-30551, 31055). The series from Great Glacier is inter- 

 mediate between Sorex obscurus obscurus and ^S*. o. longicauda, but on 

 the whole is nearer Imigicauda. 



Neosorex palustris naVigator Baird. "Water Shrew 

 An adult male (no. 30568) was trapped near Telegraph Creek on 

 June 22, in a bit of swampy land near the stream. Allen (1903, p. 567) 

 has referred the water shrew of this region to Neosorex palustris alas- 

 hanus (Merriam), but our one specimen does not exhibit the characters 

 ascribed to that race (cf. Merriam, 1900, p. 18). As compared with 

 Californian examples of navigator, the Telegraph Creek specimen is 

 exactly similar in general size and in skull characters, but is of slightly 

 more grayish coloration. 



I have seen one specimen of Neosorex from the coast of south- 

 eastern Alaska (in the collection of E. P. Walker), taken at Rudyard 

 Bay, about one hundred miles south of the Stikine River, and this 

 animal does exhibit the cranial peculiarities ascribed to alaskanus. It 

 seems likely that the latter is confined to the coastal region.
