Genus LITHOCRANIUS. (Vol. III. p. 227.) 
LITHOCRANIUS SCLATERI. 
Lithocranius sclateri, 0. Neumann, SB. Ges. nat. Freund. Berlin, 1899, p. 19. 
This name has been proposed for the form of Lithocranius that occurs in 
Somaliland. It is rather larger and has finer horns, as we have stated (see 
our remarks, vol. iii. p. 230). It is now pointed out that the typical form of 
East Africa is redder than that of Somaliland, that it has black knee-tufts, 
and shows a slight difference in the white markings of the tail. 
Genus HIPPOTRAGUS. (Vol. IV. p. 3.) 
HIPPOTRAGUS LANGHELDI. 
Hippotragus langheldi, Matsch. SB. Ges. nat. Freund. Berlin, 1898, p. 182. 
Under this name it seems that the same geographical form is described as 
that which we have called Hippotragus equinus rufo-pallidus (supra, p. 14), ex 
H. rufo-pallidus, Neumann, P. Z.S. 1898, p. 850. The type of H. langheldi 
is from Tabora, German East Africa; it is diagnosed as follows :—‘ H. bakeri 
affinis ; colli juba tricolore, subtts alba, superné brunnea nigro marginata ; 
pectore nigrescente, caude basi nigerrima.”
