PINAROCORYS NIGRICANS. 71 



a broad collar of black feathers edged with buff ; crop and breast buff, the 

 former with broad rich cinnamon centres to the feathers, which form a large 

 patch of that colour on the sides next to the lower neck ; flanks mottled 

 with rufous ; under tail-coverts buff, with the largest ones slaty grey edged 

 with buff." Iris brown. Total length 6 inches, culmen 0-5, wing 3-6, 

 tail 2-5, tarsus 0-9. The secondaries reach O'l beyond the end of the 

 primaries. 



The CoUared-Lark inhabits G-allaland. 



All that I know regarding this species, is that the type was 

 procured by Dr. Donaldson Smith during his expedition to 

 Lake Rudolf, and is now in the British Museum. 



Genus III. PINAROCOEYS. 



Similar in general structure to Mirafra, from which it differs in the depth 

 of the angle of the wing between the longest primary and longest secondary, 

 the shortest secondary falling short of the tip of the wing by about 1-2 

 inches, or more than the length of the tarsus. This genus is further 

 characterised by the variable pattern of the plumage in adult birds ; full 

 plumaged birds have the crown and back uniform brown ; quills with or 

 without a rufous pattern, and most of the centre ones have broad pale 

 terminal margins, but these strongly marked variations in the colouring of 

 the wings are neither seasonal nor specific characters, but apparently denote 

 the sex. 



KEY TO THE SPECIES. 



a. Upper tail-coverts and tail blackish brown, nigricans. 



b. Upper tail-coverts and tail cinnamon, the
