the comparison of further material shows that the bird from South 

 Africa and most of East Africa differs subspecificall}' from that of west- 

 ern and northwestern Africa, as above set forth. Apparently this 

 southern race has hitherto received no name that can be used for it, since 

 all the synonyms of the species are otherwise applicable. The original 

 Lan ins sen i'(/((/y-s '^ was of course based on the bird from Senegal ; La?i iiif< 

 eriitliTopterns Shaw,^ in so far as it relates to the present species, is from 

 the same region, as indicated by the description and part of the syn- 

 onymy cited, i. e., '"La Pie-Grieche rou.sse a tete noire du SenegaP' of 

 Daubenton,'' although it is evident that Shaw had confused the two 

 species Pomatorhynchus senegalus and Poraatorkynchus Uchagra ; 

 Tcliagra senega! enxh\jQ,^>^o\\'^ \'A also from Senegal; and Lanius coro- 

 wc^^i-^*? Vieillot '' from an unknown locality is evidently applicable to the 

 same form; while the Pojiiatorhynchus orlentalis of Cabanis,-' from 

 Mombasa, is subspecitically different from both senegalus and the pres- 

 ent race, as shown below. 



Measurements of Pomatorhynchxis senegalus armenus are as follows:

PomatorhyncJnis orlentalis Cabanis, von der Decken's Keisen, III, 1869, p. 27, in 

 text (Mombasa, British East Africa). 



A series of eight specimens from Mombasa, the type locality, shows 

 that this form, hitherto usually considered inseparable from Pomator- 

 hyncJius se/iegalus, is well worthy of recognition. It differs from true 

 P. senegalus of western Africa in its inferior size, more slender bill, 

 and decidedly paler upper surface; and from P. senegalus arinenns by 

 reason of its smaller size, much paler, more grayish upper surface, 

 and less butt}' lower parts.
