[This little Lark was very numerous in the acacia-country on the plains around the 

 south end of Ruwenzori, but was not seen on the mountains above an elevation of 

 4000 ft. While hovering in the air it makes a curious drumming noise with its 

 wings. — R. B. W.']

I have compared the above-mentioned series of specimens with the type of M. trojji- 

 calis Hartert, from Bukoba on the west coast of Lake Victoria ; they agree perfectly 

 with one another and evidently represent a well-marked subspecies. Dr. Hartert has 

 already pointed out that Captain Shelley was mistaken in supposing that M. occi- 

 dentalis (Hartl.) from Gaboon is synonymous with M. tropicalis, and has shown that 

 the former is in reality more nearly allied to the South African form M. africana 

 [cf Bull. B. O. C. xix. pp. 93 & 94 (1907)]. 



[Hartert's Rufous-naped Lark was plentiful on the plains around the south end of 

 Ruwenzori, but was not found on the mountains. It frequents the acacia-country, 

 and is constantly to be seen perched on the top of some low bush uttering from time 

 to time a long single note. — R. B. W.'\

[The African Pied Wagtail was met with throughout the journey, and occurred on 

 Ruwenzori up to an elevation of 7000 ft. It was an extraordinarily tame and familiar 

 bird, seeming to prefer the vicinity of habitations. At each base-camp formed by the
