vot. Iv.] Motes on a Collection of Mammals. 317 
Mr. W. E. Bryant for aid of various kinds in the preparation of 
this paper. The numbers used throughout the paper are the 
serial numbers of the mammal collection in the University 
Museum. 
1. Zamias quadrimaculatus Gray. 
This species, of which six specimens were taken, was found 
only at two localities, Summit Station and on Mt. Tallac. They 
are all in worn pelage, having not yet attained their fall coat, but 
all show on the flanks, patches of rich ferruginous that cannot be 
mistaken. The series varies somewhat in intensity of color, 
although they were all collected within a period of three weeks, 
Two specimens, No. 51, a male, taken July 31, and No. 97, a 
female, taken August 12, on Mt. Tallac at about 8500 feet eleva- 
tion show the highest coloration. In one specimen, No. 66, a 
male, nearly all the outer coat has been shed, leaving the soft 
black under pelage, through which the new hairs of the stripes 
are beginning to show. 
Little is known of either the horizontal or vertical distribution 
of this species. It is considered by Dr. Allen a Sacramento Valley 
form, and is recorded from the following localities: Nevada City, 
Nevada County; Fort Crook, Shasta County; Baird, Shasta 
County; Mt. Shasta, Lassen County; and from Fort Klamath, 
Oregon. Asis readily seen, none of these localities are in the 
Sacramento Valley. They are all in the lower portion of the 
pine belt which covers the western slope of the Sierras down to 
an altitude of about 1500 feet in the Mt. Shasta region and to 
about 2500 feet in Central California. The discovery by 
the writer that Zamdas quadrimaculatus inhabits the upper slopes 
of Mt. Tallac was unexpected, and goes to show that from 
Nevada City northward this species probably inhabits the entire 
western slope of the Sierra down to the limit of evergreen forests. 
Its extension southward is still unknown. 
Gray’s type of Zamias quadrimaculatus came from Michigan 
Bluff, which stands at an elevation of 3500 feet, some fifteen 
miles in a direct line due south of Blue Cafion, and about half 
that distance from Red Point. The three localities present simi- 
lar conditions, standing at approximately the same elevation, 
and all included in the great belt of yellow and sugar pine.
