TELEGONY AND REVERSION. 123 



differs in his markings from the less remote ancestors of 

 his dam. 



To recapitulate : Romulus^ in having- numerous narrow 

 arches across the forehead, differs greatly from his sire, 

 and in a less degree from the Norwegian pony ; in having 

 twenty-four cervical stripes he differs from his sire, but 

 closely agrees with the Transvaal zebra filly when the 

 shadow stripes are included ; in having over forty stripes 

 between the shoulder stripe and the root of the tail he 

 is surprisingly unlike his sire, in which there are only 

 five distinct transverse body stripes ; and in having at 

 birth well-defined spots over the croup and rump, he 

 differed not only from his sire but from all the other 

 zebras ; and if in Mr. Darwin's striped colt we had a 

 restoration of a lost chapter in the history of the horse, 

 Romulus also differed in this respect from the less remote 

 ancestors of his dam. As already pointed out, Romulus 

 in the brow markings and in the numerous stripes running 

 at right angles to the dorsal baud, more or less accurately 

 agrees with the Somali zebra, with which he also nearly 

 agrees in the relative length of the head, the markings 

 within the two divisions of the shoulder stripe, and over 

 the rump and hind quarters. Further, at birth his muzzle 

 resembled in colour that of the Somaliland zebra. These 

 resemblances to the Somaliland zebra become doubly 

 interesting when it is remembered that there are excellent 

 reasons for believing this zebra to be more primitive than 

 all the other living zebras. They, in fact, all but prove 

 that in the striping of Romulus we have a remarkable 

 instance of reversion. Additional evidence of reversion 

 we seem to have in the intermediate spaces in the hybrids, 

 being at first of a yellowish-brown colour, and the mane 

 being nearly upright, and in the tail having only persistent 

 hairs at the tip. But even stronger evidence in this 

 direction is afforded by the spots which at birth were 

 scattered over the hind quarters. I am satisfied these 

 spots have no relation whatever to the dappling- so often 

 seen in recent horses. Dappling, I believe, has been
