16 THE PENYCUIK EXPEEIMENTS. 



continued some distance into the mane by light browu 

 hairs. The last pair of cervical bands meefc^ as in the 

 zebra, in the middle line over the sternum, and become 

 continuous with a broad but not very well-defined ventral 

 band, consisting of long dark brown hairs. Running 

 downwards across the trunk, behind and nearly parallel 

 with the shoulder stripe, are nine bands, which take the 

 place of the four or five broad vertical bands in Burchell's 

 zebra. Behind these are a number of oblique bands 

 which curve upwards and backwards, the lower extending 

 across the hind quarters. In the space between the 

 vertical and oblique bands are a number of indistinct 

 narrow stripes, while over the croup and rump there are 

 rows of spots. In having these spots and narrow stripes 

 over the hind quarters and loins the hybrid differs from 

 all the zebras. 



It will be interesting to note if there is a like failure to 

 develop distinct broad bands over the hind quarters in 

 hybrids that may afterwards be obtained. The remark- 

 able decoration of the hind quarters is more likely to be 

 due to reversion than the elaborate decoration of the face. 

 It may even have some relation to the dappling so common 

 over the hind quarters in most breeds of horses. There is 

 a distinct dark dorsal stripe, with a yellow line at each 

 side, extending along the spinal ridge to the root of the 

 tail. The dorsal band, narrow in front, expands con- 

 siderably as it proceeds backwards. The tail, as in the 

 zebra, has several cross-bars at its root. In the reo-ion of 

 the shoulder-joint there is again a failure to form distinct 

 stripes, but there are numerous bands across both the fore 

 and hind Hmbs. Twenty-four bars were counted on the 

 left fore-limb, and thirty-one on the left hind limb. The 

 twelve below the " knee " run obliquely downwards and 

 backwards, and become fainter as the fetlock is reached, 

 while those on the "knee" and the forearm are well marked, 

 and almost form complete circles. In the hind limb the 

 bands above and for a short distance below the hock are 

 extremely well marked, while those on the shank and over
