The dark tail rings are very broad and black, and the tail is 

 extensively blaek-tipped. 



Sorex vancouverensis C. H. Merriam 

 Vancouver Island Shrew 



Found in abundance at nearly every point visited. We 

 collected in all 105 specimens on Vancouver Island (nos. 12485- 

 12587, 12602-12604), from Parksville, Little Qualicum River, 

 French Creek, Errington, Beaver Creek, and the Golden Eagle 

 Basin. The only placas where trapping was carried on, and 

 where we failed to find shrews, was on Douglas Mountain and at 

 Nootka Sound. At the former locality we secured nothing in 

 the traps, and at Nootka the small mammal trapping was some- 

 what neglected in favor of bird collecting. 



Two species of shrews are supposed to occur on Vancouver 

 Island, Sorex vancouverensis and S. ooscurus (Merriam, 1895, 

 pp. 70, 72), but I am unable to distinguish more than one form 

 in the material we collected. Two specimens were trapped on 

 the mainland, in Stanley Park, Vancouver (nos. 12483, 124S4) 

 which, for geographical reasons, should belong to the subspecies 

 S. ooscurus longicauda (see Merriam, I.e., p. 74), but although 

 they are larger than any of the individuals composing the island 

 series, they do not differ from them in color or proportions. 

 They measure respectively: length, 120, 117; tail, 52, 52; hind 

 foot, 13, 14. The average and extreme measurements of ten 

 males from Vancouver Island are as follows: length, 106.9 (104- 

 112) ; tail, 46 (41-52) ; hind foot, 13 (12-15). 



My otis lucifugus alascensis Miller 

 Alaska Brown Bat 

 A brown bat taken at Errington, August 31 (no. 12588), I 

 have provisionally referred to this form. The specimen is so 

 imperfect as not to admit of exact identification. 



Small bats (apparently some species of Myotis) were fairly 

 common at several points. At Beaver Creek I saw but few, and 

 the days being very long then, it was not dark enough for bats 

 to appear until nearly ten o'clock, so there was little chance to
