 district, and one from Zoulla on the shores of the Red Sea 

 near Massowah collected by Blanford. The Arabian birds 

 are referred by Hartert to Tristram's species. We have 

 seen Palestine examples in the Tring Museum and are in 

 agreement with this view.

Claude Grant has monographed this group of Nightjars 

 in ' The Ibis,' 1915, pp. 306-308, and we agree with his 

 conclusions. In the Proceedings of the Biological Society 

 of Washington, xxvi. 1913, p. 167, Dr. J. C. Phillips describes 

 a new Nightjar under the name of ( 'aprinmlgns eleonorcf from 

 Fazogli. Mr. A. L. Butler, Ibis, 1915, p. 181, who has seen 

 Dr. Phillips' coloured plate, unhesitatingly identifies it with 

 the above species,

This little long-tailed Nightjar, according to Mr. Butler 

 probably the commonest of its family in the Sudan, has a 

 remarkable range of variations. These variations are 

 generally geographically constant, but not always. They 

 cannot therefore be regarded as subspecies, unless one
