and a tubercle in place of a fifth toe : the tail is 

 covered with spines for about a third part of its 

 length ; the remainder being nearly naked, and 

 strongly prehensile. In the Leverian Museum is 

 a very fine specimen of this animal.

Mexican Porcupine. Pennant Quadr. z.p.i2,$. 



THE Mexican Porcupine, which is placed as a 

 variety of the Hystrix prehensilis in the Gmeli- 

 nian edition of the Systema Naturae, seems to be 

 justly considered by Mr. Pennant as a distinct 

 species. It is as large, according to Hernaiides, 

 as a middle-sized dog, and is of a dusky brown 

 colour, with very long bristles intermixed with 

 the fur : the spines, with which the upper parts 

 are covered, are about three inches long, slender, 

 and varied with white and yellow, and are not 

 very apparent through the hairs, except on the 

 tail, which is much thicker and shorter in pro-

 middle to the end. This animal inhabits the hilly 

 parts of Mexictf, residing in woods, and feeding,
