ZEBRAS AND QUAGGAS 201

 P7'oceedings for 191 1 (reproduced in pi. xviii. fig. 2) 

 is represented with a full and bushy mane and 

 forelock. In this respect it resembles the closely- 

 allied Kilimanjaro race. Whether the absence of 

 the mane and forelock in the Gwaseno-ishu indi- 

 viduals is a seasonal or a permanent feature can, 

 of course, be definitely determined only by observa- 

 tions made at different times or year. The fact 

 that no complete seasonal shedding and loss of 

 the mane has been recorded in the case of specimens 

 of the more southern races of bontequagga kept 

 in menageries renders it almost certain that the 

 feature is permanent. Assuming this to be the 

 case, it is noteworthy that the Masai bontequagga is 

 one of the most northern representatives of its 

 kind, and that within the limits of the range of that 

 race the tendency to the loss of mane and the 

 acquisition of almost completely white backs to 

 the ears attains its full development only in the 

 more northern districts. In the domesticated horse 

 it is ascertained that no seasonal sheddine of 

 the hairs of the mane and tail takes place, and 

 that for the most part these continue to grow 

 throughout life. 



In 191 1 a curious "sport" was recorded among 

 a few of the Masai bontequaggas inhabiting the 

 Nakura district of British East Africa. These 

 bontequaggas, which have unfortunately received
