has, however, the appearance of youth and matches very 

 closely, except for size, an example of C. e. umvmi from 

 Sirsa in the Punjab now in the Museum. We can only 

 provisionally identify it with this species. Dr. Hartert has 

 also examined this bird and writes, " If not a young C. e. 

 unwini — and I do not think it is, being so very small — it 

 must be an unknown species or a hybrid, for it is not any 

 otiier known species."

This Nightjar was met with by Mr. Butler in the Kajo 

 Kaji plateau, but is not represented in the collection in the 

 Museum. 



One of Dr. Christy^s examples is in the grey phase and 

 three are in the red phase. This latter, judging by the 

 series in the Museum, is more usually met with to the 

 westward, while the birds from Bogosland and Somaliland 

 are more usually in the grey phase ; but some of these latter 

 approach the reddish phase, though the colour is never so 

 rich as in the West African examples. A nestling from 

 Mt. Elgon collected by R. Kemp is distinctly in the red 

 phase.

We have followed Claude Grant in his revision of the 

 races of this Nightjar, though we have grave doubts as to 

 whether this subspecies is really separable from C. n. 

 natalensis. The wings of our specimen measures ^ ^ 154, 

 156, 160, 161 mm., ? ? 149, 152 mm.
