HOWELL CALIFORNIA BAT ROOSTS 177 
cave must have been twenty degrees warmer than the outside air, these bats were 
undoubtedly settled for the winter. This locality, on the coast side of the moun- 
tains, constitutes an extension of range for the species. 
5. Beneath an awning on the Barbara Worth Hotel, El Centro, Imperial 
County. About one hundred Yuma bats October 8. 
6. In the adobe store-house at Fort Tejon, Kern County. A thousand 
Tejon bats September 3; two hundred September 23; and none December 16. 
In the cracks between the adobe bricks and the roof of the adjoining ranch house 
are many Antrozous during the summer. 
7. In the attic of a large building near Azusa, Los Angeles County. Sixty or 
seventy large brown bats mixed with a few Mexican free-tails. All were females, 
and a few of .the former had small young May 31. At the other end of this attic 
there is a colony of Eumops. 
, 8. In the attic of a three story house near Covina, Los Angeles County, a 
mixed colony of one hundred or more pallid bats and free-tails. Now walled in. 
In the loft of the garage to this house I have at different times taken several 
single free-tail and large brown bats. 
9. Hay loft above a stable near Covina. A mixed colony of one hundred free- 
tail and pallid bats hidden in the cracks between the shingles and the end walls. 
In a crack under the veranda roof of the adjoining residence is a small colony of 
free-tails. 
10. Intheloftofa desertedwinery near Cucamonga, San Bernardino County. A 
colony of twenty-five large browns and five free-tails — all females — in the space be- 
tween a sliding door and the wall, April 25. Large piles of guano beneath the 
ridge may indicate that more bats are here later in the season, or that the spot is 
used as a feeding station. 
11. In the attic of the residence of R. B. Herron, San Bernardino. Two hun- 
dred free-tails of both sexes, November 5. The owner states that there are 
several thousand here during the summer, and that a larger form, probably 
Antrozous, is present. Visited with L. Little. 
12. Under the awnings of the Hollywood High School, Hollywood, many 
pallid bats insist upon staying, in spite of all efforts to drive them away. 
13. In the cornice of the Grammar School at Colton, San Bernardino County. 
An unknown number of free-tails. Kindness of W. C. Hanna. 
14. Behind a sign on the side of the High School at Colton. An unknown 
number of free-tails. Kindness of W. C. Hanna. 
15. In the false, second story front of a one-story building near Azusa. Per- 
haps fifty free-tails. 
Besides the colonies of mastiff bats, reported in another paper, I know of 
several other colonies of Antrozous and Nyctinomus in Los Angeles and vicinity, 
but these “belong” to other men, and I have never visited them. I have also 
heard a rumor of a colony of Tejon bats near one of the southern beaches.
