PROF. W. RIDGEWAY ON THE 



[May 11, 



skins of a male and a female Grevy Zebi^a shot by the late 

 Mr. A, H. Neumann at Euaso Nyiro at an altitude of 3000 ft. 

 Both specimens lack the small stripes commonly found in speci- 

 mens from Somaliland and Shoa, and which correspond to the 

 " gridiron " of the Mountain Zebra. Text-figs. 148 & 149 ishow the 

 skins of a male and a female of Grant's variety from Baringo 

 (3000 ft.). The former shows faint, the latter more marked 

 vestiges of the croup or " gridiron " stripes, thus showing a slight 

 approximation in colouring to the Grevy and Mountain Zebras.

E. hiirchelli (Bristol). 



Text-figs. 150 &L 151 exhibit two skins (male) from Laikipia 

 (5800 ft.). Text-figs. 152 tfc 153 give the skins of a male and a 

 female from Uasingishu (6500 ft.). Next comes that of a male 

 from Kinolop (7500 ft.), whilst text-fig. 155 is that of a male 

 from the north end of the Aberdare Range (8000 ft.). The last 

 has longer hair than the rest. The variation in the skins from 

 different localities and altitudes is obvious. This is in accord 

 with the testimony of that excellent observer, Mr. A. H.Neumann, 

 who (' Elephant-hunting in East Equatorial Africa,' p. 372)
