secure them. One was seen at Friendly Cove, the evening of 

 July 23. 



At the head of Great Central Lake, August 17 to 25, bats 

 were irregularly abundant, sometimes six to eight suddenly 

 appearing at once, skimming over the surface of the water, to 

 disappear again as quickly as they came. They were quite 

 numerous at Errington, 'throughout September, but seldom came 

 out until late in the evening, and remained in the woods where 

 it was almost impossible to shoot them. The one secured was 

 shot at such close range as to be badly mutilated. 



Eptesicus fuscus (Beauvois) 

 Brown Bat 



Two specimens taken at Errington (nos. 12589, 12590) on 

 August 30 and September 25, respectively. The species was 

 fairly common here, but was not positively identified at any 

 other point. 



The two collected are darker colored than most examples 

 from southern California, but are exactly like specimens at hand 

 from Humboldt County. The dorsal surface is Vandyke brown, 

 the under surface wood brown. 



GENERAL REMARKS ON DISTRIBUTION 



Though the one season's work js not sufficient to supply data 

 for the accurate definition of the life-zones of Vancouver Island, 

 it is in general confirmatory of the division indicated on the 

 zone map in the 1910 edition of the A. O. U. Check-List. That 

 is, that the extreme southern tip of the island, and a narrow 

 strip on the east coast, south of the center, is Transition Zone: 

 the remainder, by far the greater part of the island, Canadian, 

 with the exception of the limited area of Hudsonian and Alpine- 

 Arctic on the mountain tops. The following generalizations, and 

 the accompanying lists are tentative, to the last degree, and will 

 probably require extensive revision with additional work in the 

 region. They represent conditions as noted during brief visits 

 at various points during a single season, and as such may serve 

 for comparison with further observations.
