Adult. Head, which is ornamented with a long crest, and entire 

 upper surface glossy greenish black, the tail tipped with white ; pri- 

 maries brown, white at the base both internally and externally, 

 forming a large white alar spot ; sides of face black ; under surface 

 entirely dull white, with a yellowish tinge on the throat and breast ; 

 under wing-coverts yellowish white, the lower ones greyish ; flanks 

 shaded with dusky grey ; bill and feet black ; iris yellow. Total 

 length 136 inches, culmen 1, wing 6*4, tail 8, tarsus 1*15. 



Young. Brown, the quills paler ; tail brown, tipped with white, 

 the centre feathers glossed with greenish ; a white alar spot as in 

 adults ; under surface of body entirely yellowish white, the lower 

 under wing-coverts brown; bill horn-brown. 



I cannot find any real difference between Indian and African 

 specimens of this Cuckoo ; and the measurements show that there is 

 only one species. 



Hab. N.E. Africa : probable migrant — Bogos in August, 

 Senaar in September, Chartum and Berber in November {Von 

 Heuglin) ; Anseba valley (Stanford) ; Autrub on the Blue Nile 

 (Antinori) ; Ambukol in Nubia (Ehrenberg). E. Africa : Mom- 

 bas (Wakefield). S. Africa : Tette (Livingstone) ; Natal, Trans- 

 vaal ( Ayres) ; Eland's Post (Atmore) ; Lake N'gami (Anders- 

 son). S.W. Africa: Damara Land (Andersson) ; Biballa (An- 

 chieta). 



The adult specimen described was a Damara skin ; and it is from 

 this and the adjoining region that the largest specimens come. The 

 difference in general bulk and in length of tail is very great, even in 

 specimens from the same locality.
