3. Passer griseus suaheltcus. 



Passer griseus suahelicus Reichw. Vog. Afr. iii. p. 231 : 

 German East Africa. 



Range. German East Africa and Nyasaland, north along 

 tlie coast to Lamu in British East Africa, where it occurs 

 side by side with P. gongonensis Oust. The latter therefore 

 must be considered a different species. 



Back a little brighter than in P. g. diffusus, but a hardly 

 definable race. It is really intermediate between P. g. 

 diffusus and the next race. Hardly distinguishable from 

 P. g. griseus, except that the underparts are usually duskier. 

 Wing 83-90 mm.
