Birds from British East Africa and Uganda. 35 



On comparing two young males, one from Senegal and 

 the other from Uganda, the same differences are apparent ; 

 the eastern l>ird being considerably darker and broader in 

 the markings of the upper surface and having more black 

 on the l)elly ; this latter may, however, be only individual. 



Wing: S (() ad. measured j 183-201 mm.; ? (4 ad. mea- 

 sured) 177-187 mm. 



Type, c? ad. Reuk, AYhite Nile. 12. v. 1901. R. ]\r. 

 Hawker Coli. in British Museum. Wing : 201 mm. 



This is the east African fonn^ and ranges down the Nile 

 Valley to Uganda and B.E.A. 



Named in honour of Mr. Willoughby P. Lowe. 



There are therefore two races of this Sand-Gi*ouse as 

 follows : — 



Pterocles quadricinctus quadricinctus Temm. Pig. et 

 Gall. iii. 1815, pp. 252, 71^: coast of Coromandel, error &=■ 

 Senegal, W. Africa. 



As there can be little doubt that this Sand-Grouse does 

 not range across into India, the locality of Coromandel is 

 incorrect. In the Pig. et Gall., p. 254, it will be found 

 that Temminck based the locality of Coromandel on the 

 authority of Sonnerat. Later, in the PI. Col. v., under 

 P. liclitensteinii he remarks : — " La preuve certaine que le 

 Ganga quadrubande a ete trouve non seulement sur la cote 

 de Coromandel, mais encore sur une grande etendue de cotes 

 d'Afrique ; j'en ai reeu plusieurs individus du Senegal." 



So that, as Temminck himself has given a locality in 

 Africa for this species, the type locality in future should be 

 designated as " Senegal, West Africa.^' 



Paler, less broadly marked, mere " bloom ^' above. 



Wing : $ (5 measured) 173-185 mm. ; ? (2 measured) 

 177-180 mm. 



A young male from Seuegal measures 179 mm. This is 

 the only specimen available from the type locality. 



Two adult females from Bahr-el-Ergig River, south of 

 Ft. Lamy, Lake Chad district, appear to belong to the
