304 Mr. C. H. B. Grant on a Cdlection of 



A large race, having the wing in males 163-157 mm. and 

 in females 163-149 mm. 



Range. Natal and Zululand. 



Caprimulgus natalexsis fulviventris. 



Caprimulgus fulviventris Hartl. Journ. fiir Orn. 1861, 

 p. 102 : Bembe, Angola. 



Size about as in C. n. natalensis ; general colour much 

 more fulvous. Wing: 154 mm. The type, a male, judging 

 by the markings of the wings and tail, is the only specimen 

 available. 



Range. Angola. 



Caprimulgus natalensis accrue. 



Caprimulgus accra Shelley, Ibis, 1875^ p. 379 : Accra. 



Size rather smaller than in C. n. natalensis; general 

 colour much greyer {cf. Ibis, 1912, pi. iv.). Wing: in 

 males 154-151 mm. ; the type, a female, judging by the 

 markings of the wings and tail, has the wing 149 mm. 



Range. Gold Coast Colony and Liberia. 



Caprimulgus natalensis chadensis. 



Caprimulgus chadensis Alexander, op. cit. 



Similar in plumage to C. n. natalensis -, size, perhaps on 

 the average, smaller. Wing: ^ 159-150 mm.; ? 159- 

 146 mm. The two types, a male and a female, measure 

 respectively 153 mm. and 147 mm. 



Range. Uganda, Egyptian Sudan, Welle River and Lake 

 Chad Districts. 



In his description Alexander compared his birds with 

 C. accrue, from which, of course, the Lake Cliad birds are 

 quite different, instead of with the parent race C. natalensis^ 

 from which the Lake Chad birds only differ in being slightly 

 smaller. Had this bird not been named by Alexander I 

 should have felt inclined to place the northern African bird 

 under C. n. natalensis ; but seeing that a name is available, 

 that a difference in size, though slight, does exist, and 

 that a gap of 2000 miles at least separates the southern 

 and the northern localities, I feel justified in keeping up 

 C. n. chadensis.
