Equus Caballus. 243 



Ass is sometimes found of yellowish white, without any cross, in 

 its domesticated state. Mr. Cross informs me, that a year or two 

 ago, a specimen said to be of this species was brought to this coun- 

 try. 



This family (which is distinguished from all other animals by 

 its undivided hoof, formed of the two anterior toes, soldered to- 

 gether, its simple stomach, and its female having the teat placed on 

 the pubes,*) may be divided into two very distinct types of form ; 

 the one the Asses and Zebras, which are always whitish and more 

 or less banded with blackish brown, and always have a distinct 

 dorsal line, the tail only bristly at the end, and have warts only 

 on the arms, and none on the hind legs ; and the true Horses, 

 which are not banded, have no dorsal line, are furnished with 

 wartst on their arms and legs, and have long hair on the tail, from 

 its insertiou to its extremity.

* Linneus observes that mares mammas non habent, which is not the fact, for 

 he ought to have said mares mammas prepuciales habent.
