Typical locality Eastern Sudan or Southern Abyssinia. 



A variable species in which the dark areas are never so 

 large or so red as in reticulata, while the light ones do not 

 form such a coarse and distinct network, and are very 

 frequently tawny instead of white. Typically the colour- 

 pattern consisting of a chestnut ground cut up into moderate- 

 sized and more or less ruimded patches hy a network of 

 light lines; the shanks white; and the anterior horn well 

 developed. From this type there is a gradation to one in 

 which the colour-pattern consist of small brownish or chest- 

 nut blotches on a fawn ground, the shanks fawn-coloured 

 and spotted down to the hoofs, and the anterior horn obsolete. 



The following is a tentative " key " to the named local 

 races, based on males only : 



A. Anterior horn well developed. 



a. Front shanks (in adult males) wholly white, 



and hind ones mainly so. 

 a 1 . No occipital horns. 

 a 2 . Colour richer. 



a 3 . Spots large on upper part of fore- 

 legs G. c. camelopardalis. 



6 3 . Spots becoming suddenly small on 



upper part of fore-legs G. c. antiquorum. 



6 2 . Colourpaler G.c.peralta. 



b l . Occipital horns present. 



a*. Occipital horns small, a process over 

 right orbit ; spots rufous brown ; 

 sides of face not spotted above line 

 connecting eye with angle of mouth G. c. cottoni. 



6 4 . Occipital horns larger, typically no 



process over right orbit ; spots 

 darker ; sides of face fully spotted 

 in sub-adult males G. c. rotliscliildi.
