1918] Grinnell: A Synopsis of the Bats of California 355 
northwestern Mexico.’’ In California the range is through the Lower 
and Upper Sonoran zones on the Pacific slope, from the Mexican line 
north through the San Diegan district and San Joaquin Valley, and 
through the central coast district as far as Marin County. Recorded 
also from Fort Crook (near Burgettville), Shasta County (Miller, 
1897b, p. 45). The specimen from Goose Lake, Modoc County, exam- 
ided by me differs somewhat from other specimens of Antrozous which 
I have seen and suggests the existence in the northern part of the 
the Great Basin of a race, as yet unnamed, externally most nearly like 
pacificus. (See map, text-fig V.)

Natural History—During the summer of 1904 the writer became 
acquainted with a colony of the Pacifie pallid bats which occupied 
the spaces under the eaves of a barn loft at Glendora, Los Angeles 
County, in company with a few Mexican free-tailed bats. Every 
morning the floor of the loft was found to be strewn with heads, legs, 
and wings of insects caught by the bats. Most numerous among these 
? 
‘‘kitehen middens’’ were heads and legs of Jerusalem crickets and 
the wings of sphinx moths. Dr. H. C. Bryant of the State Fish and 
Game Commission has kindly identified a sample lot of these remains, 
picked up in September, 1904, as belonging to the following genera 
and species of insects: Prionus californicus, Stenopelmatus sp., Deile- 
phila lineata, Microcentrum sp., Ligyrus gibbosus, and Gryllus sp. 
It is of interest to note that the Jerusalem crickets (Stenopelmatus),
