MONOGRAPH OF THE GENUS SCIUltUS. 155 



rich I also found what I conceive to be the same species; 

 and in the British Museum there is a specimen obtained at 

 Texas by Douglass, agreeing with the others in almost every 

 particular. I find also among my notes a description of a 

 specimen received by a friend from the south-western parts 

 of Louisiana, which, on a comparison with memoranda taken 

 of the other specimens, I do not find to differ in any impor- 

 tant particular. It is probable therefore that this species has 

 a pretty extensive range, from the south-western portions of 

 Louisiana, through Texas, into Mexico. Of its habits I pos- 

 sess no information. 



The Texian squirrel is about the size of the fox squirrel. 

 On the upper surface there is a mixture of black and yellow, 

 and on the under parts deep yellow. The under sides of the 

 limbs, and also the parts of the body contiguous, are whitish 

 at the base. Fore legs externally, and the feet, rich yellow. 

 Ears on both surfaces yellow, with interspersed white hairs. 

 Nose and lips brownish white. Hairs of tail rich rusty yel- 

 low at base, with a broad black space near the extremity, 

 and finally tipt with yellow.

The Texian squirrel bears some resemblance to the Sciu- 

 rus capistratus ; the latter species however in all the varie- 

 ties I have examined, has uniformly the white ears and nose. 

 I am moreover not aware that the Set. capistratus exists in 

 the south-western parts of America, where it seems to be re- 

 placed by the present species. 



3. Golden-bellied Squirrel. Sciurus sub-auratus, (n s.) 



Essent. Char. — Size intermediate between the Northern Grey and the 

 Little Carolina Squirrel ; tail longer than the body ; colour above grey, 

 with a wash of yellow, beneath deep golden yellow.

In the two specimens now before me, and which are very 

 similar in size and markings, there is no appearance of the 

 small anterior upper molar found in several other species of 

 this genus. I conclude therefore that it either does not ex- 

 ist at all, or drops out at a very early period ; and have ac-
