ZEBRA-HORSE HYBRIDS. 45 



frog. 1 may add, the nostrils are in their shape a little 

 less zebra-like than in the other hybrids ; that the muzzle 

 suggests the dam more than the sire, the lower lip being, 

 as in the dam, somewhat long; and that the rounded ears 

 are tipped with white, as is occasionally the case in dun 

 ponies as well as in zebras. As might have been expected, 

 the trunk and hind quarters are more massive than in 

 Remus, Avhile the shoulders are less upright, and perhaps 

 as a consequence of this the action at all times is less 

 zebra-like than in any of the other hybrids. As Fig. 12 

 indicates, there is a " swirl " nearly three inches in length 

 extending down the centre of the face between the eyes. 

 The same figure also indicates fairly well the extent of the 

 marking at the end of the second month. The brow 

 arches (hardly visible in the figure) are nearly as pointed 

 as the frontal arches in a Norwegian pony in my posses- 

 sion, and as in the Amsterdam quagga. This is very 

 remarkable, as in all the other hybrids the brow stripes 

 form rounded arches. The cervical, and in fact all the 

 other stripes as far as they go, agree with the corresponding- 

 stripes of Romulus. In the region of the shoulder the 

 markings are very faint, and over the hind quarters only a 

 few indistinct spots and portions of bands can be detected. 

 The lower part of the legs is only faintly striped, and even 

 the bars across the forearm and the hock are more obscure 

 than usual. But although none of the stripes are very 

 pronounced, there are, strange to say, faint lines between 

 several of the cervical and vertical body stripes. These 

 lines suggest " shadow " stripes, and seem to correspond 

 to some of the numei'ous indistinct vertical stripes seen in 

 zebra-ass hybrids. In having faint intermediate vertical 

 stripes, this, on the whole, horse-like hybrid may be said 

 to be, in at least one respect, more primitive than either 

 of the other hybrids already described. If this hybrid 

 continues to- thrive, she ought to grow into a powerful, 

 active, shapely cob, about fourteen hands in height, hardier 

 and with more staying power than an ordinary mule.
