stating that he could not tell where it had been obtained ; the specimen 
has from that time remained in our collection without our having been 
able to gain any information in regard to its habitat, and without our 
learning that any other specimen has been procured, although we have 
anxiously sought to obtain farther intelligence on the subject. 
This family is represented in the old world by few and peculiarly 
marked species, to none of which can we refer our animal, whilst on the 
other hand it bears in form, size, and markings, a strong connection with 
the American spermophiles, and will, as we are inclined to think, yet be 
found in some part of the western sea-coast regions of America. 
W e introduce it under the following name and description : 
SPERMOPHILUS PEALEI.-Aud. and Bach. 
S. TamiS Lysteri paullulum major ; striis albis quinque, cum quatuor 
fuscis alternantibus. 
CHARACTERS. 
A size larger than Tamias ‘Lysteri ; jive white and four brown stripes. 
DESCRIPTION. 
Head, smaller and shorter, and ears considerably longer and less 
abruptly terminated than in Say’s S . lateralis : it is a little smaller than 
that species ; legs more slender, and tail longer, broader, and more dis- 
tichous than in S. lateralis ; whiskers, long, a few of them extending beyond 
the ears. 
On the fore feet there are four toes, without any vestige of a thumb or 
nail ; the claws are short and small, and are covered with hair ; palms, 
naked ; there are five toes on each hind foot ; the hair on the body is short 
and smooth, but is a little longer and also coarser on the under surface. 
COLOUR. 
A narrow white stripe rising on the back of the head runs along the 
centre of the back (or dorsal line) to the root of the tail ; another white 
stripe on each side originates behind the ear and runs along the upper part 
of the side, narrowing on the hips till it reaches the sides of the root of the 
tail ; a second white stripe on each side (lower than the last mentioned)
