 32^ inches. 



The Mweru race (C. d. crawshayi), from the Lake Mweru district 

 and other parts of British Central Africa, described by Dr. P. L. 

 Sclater on p. 726 of the Zoological Society's Proceedings for 1893,

 colour of the back is, for instance, described as being dark iron-grey, 

 approximating to that of the true waterbuck, but darker, and passing 

 into blackish on the back of the neck, upper part of the legs, and

passing into whitish on the under-parts. All the known horns of this 

 race are relatively small as compared with the Uganda race, the 

 maximum recorded length being 29 inches. 



With the Gambian race, or sing-sing (C. d. singsing}, we again 

 come to a rufous type near akin to the typical Abyssinian race, but 

 with a smaller amount of white in the neighbourhood of the eye. The 

 range of this race includes Sierra Leone and a large part of Nigeria.

 the Hon. Walter Rothschild in Novitates Zoologies for 1895 (vol. ii. 

 p. 52) on the evidence of specimens obtained by Mr. G. W. Pcnricc 

 about one hundred miles south-west of Bcneucla. In the original
