VESPERTILIS PALLIDUS, L e c o n t e .White Bat. 



Vespertilis pallidus, LECONTE, Pr. A. N. Sc. Phil. 



Of this white bat several specimens were collected. 



LYNX RUFUS var. MACULATUS. Texas Wild Cat. 



BATED, Gen. Rep. Mammals, 1857, 93. 

 Sr. CH. Similar to the common wild cat, but with the general color red, with numerous duslcy spots. 



A specimen collected in the Tejon valley agrees pretty well with skins from the Eio Grande 

 of Texas. The prevailing color is pale reddish, the tips of the hairs yellowish gray. The 

 dorsal region is rather darker, and exhibits some faint longitudinal dark lines. Numerous 

 rounded spots or blotches of darker color are scattered over the whole outer surface which, though 

 not very conspicuous, are distinctly visible. The spots are darker and more mixed with brown 

 on the legs ; the under and inner surfaces are white ; there is a faint reddish color on the throat 

 in advance of the fore legs. The belly is blotched, and the inside of the legs banded transversely 

 with black. The chin is unspotted. The ears are black inside, with a moderately large patch 

 of grayish white ; they are distinctly pencilled. The tail above is like the back, with several 

 darker bands ; the terminal fifth however is black. 



SCIURUS FOSSOR, P e a 1 e .California Grey Squirrel. 



Sdurus fossor, PEALE, Mamm. and Birds U. S. Ex. Ex. 1848, 55. BAIRD, Gen. Eep. Mammals, 1857, 264. 

 Sdurus heermanni, LECONTE, Pr. A. N. Sc. Phila. VI, Sept. 1852, 149. 



SP. CH. Size of S. vulpinus, but more slender. Tail vertebrae as long as the body; with the hairs, much longer. Five upper 

 molars Above, grizzled bluish gray and black ; beneath, white, without any differently colored separating line. Tail black, 

 with the exterior white ; the whole under surface finely grizzled. Back of ears and adjacent tuft on the occiput, chestnut. 



A specimen of a squirrel was obtained at Fort Tejon which in general character closely 

 resembles the S. fossor. The body is smaller in proportion, although as the skin has been 

 preserved in alcohol it has probably contracted considerably. There is no chestnut on the back 

 of the ear, the tuft here being dirty white. In this respect it resembles the S. leporinus of 

 Audubon & Bachman, which may prove to be the same species with S. fossor, and will have 

 priority. 



SPERMOPHILUS BEECHEYI, R i c h .California Ground Squirrel. 



Arctomys (Spermopliilus) beecheyi, RICHARDSON, Fauna Boreal i-Americana, I, 1829, 170 ; plate xii, B. IB. Gen. Rep.
