1897.] Zoology. 75 
Through the kindness of Dr. ©. Hart Merriam, I have been able to 
compare the Saturna Island series with a series of P. tavranus gambellii, 
` belonging to the collection of the Department of Agriculture, from the 
type locality, Monterey, California. . I have also made comparison with 
a large amount of material from Nicasio, California. Specimens from 
the latter place agree very closely with specimens from Monterey. The 
Saturna Island form is the darkest colored member of the texanus group, 
and is readily distinguished from either of its two nearest allies, P. 
texanus gambellii and P. texanus arcticus, by the peculiar sooty black of 
its upper parts. The new form may stand as: 
PEROMYSCUS TEXANUS SATURATUS subsp. nov. Type from Saturna 
Island, B. C., No. 2581 Sold adult, coll. of E. A. and O. Bangs. Col- 
lected by Will C. Colt, January 31, 1894. Total length 190; tail ver- 
tebræ 94.5. 
General Characters —Size and proportion about as in P. taxanus 
gambelli, from which form it differs in being very much darker in color ; 
the general tone of the upper parts sooty-black instead of yellowish- 
brown. : 
Color. —Upper parts sepia-brown, much intermixed with sooty-black, 
most intense on face and middle of back, paling off on sides ; a narrow 
and indistinct band of cinnamon along lower sides ; under parts grayish- 
white, the hairs deep plubeons basially; a black orbital ring; ears 
black, narrowly-edged with white; tail quite hairy, sharply bicolored, 
black above, white below; feet and hands white. 
Size—Average measurements of ten old adult specimens: total 
length 180.95; tail vertebre 76.20; hind foot (from dried skin) 21.25. 
Remarks.—P. texanus saturatus has a short tail, shorter than the 
head and body, and this character will always serve to distinguish it 
from any of the long-tailed mice with which it might be found, such as 
P. austerus, P. macrorhinus and P. keenii, all these having the tail longer 
than the head and body.—Ourram Banos. 
Some Bats from Lower California.—A small collection of 
mammals made by Mr. A. W. Anthony at San Fernando, Lower Cal- 
ifornia, during April, May and June, 1894, includes four species of 
bats. All of these are interesting, on account of the locality at which 
they were taken, while one, an addition to the ‘North American’ 
fauna, is very slightly known. 
In a paper on the birds of San Fernando (Auk, XII, April, 1895, 
p. 134) Mr. Anthony has given a detailed account of his collecting 
ground. “The region,” he writes, ““* * * has for its center the old
