Rhinoptilus africanus sharpei. 



Rhinoptilus africanus sharpei Erlanger, J. f. O. 1905, p. 59 : 

 South-east Africa. 



For modern work I consider the non-recording of a type 

 and the very vague type-locality given by Erlanger to be 

 inexcusable. However, to avoid creating further names I 

 use his name for this large dark race, and designate Deel- 

 foutein, central Cape Colony, as the particular type locality. 



A large, dark form. Wing : 164—148 mm. 



Range. Griqualand West, Bechuanaiand (part), central 

 Cape Colony to Orange River Colony and Transvaal. 



Rhinoptilus africanus bisignatus Hartl. 



Cursorius bisignatus Hartl. P. Z. S. 18G5, p. 87 : Ben- 

 guella, Angola. 



A small, pale form. Wing : 135 mm. 



Range. Angola. 



Only one specimen, the type, is in the National collection 

 and is paler than east African birds. This character with a 

 larger series may prove to be constant, so that I prefer, for 

 the present, to keep the Angola race separate from the east 

 African race. 



Rhinoptilus africanus gracilis Fisch. & Reichw. 



Cursorius gracilis Fisch. & Reichw. J. f. O. 1884, p. 178 : 

 Masailand. 



A small, somewhat dark race. Wing : 132-129 mm. 



Range. German East Africa, British East Africa, and 

 Uganda.
