buffy and rufous narrow bars on the breast and abdomen, and (to 

 judge by analogy with other species of CucuHus) with juvenal remiges 

 and probably juvenal rectrices as well. 



Roberts ''- has recently stated the immature (juvenal?) plumage of 

 southern birds (typical claTnosus) is wholly dark fuscous black. It 

 therefore appears that the plumage sequences of the two forms are 

 similar in the first stages, but it would be very surprising if typical 

 claTnosus were found to have a uniformly dark juvenal plumage and 

 then go through a ventrally barred immature stage to finally achieve 

 a uniform, black adult plumage. The probabilities are that it never 

 develops any barring on the underparts. 



The present series from Ethiopia, together with birds from Kenya 

 Colony and the eastern Belgian Congo, exhibits considerable varia- 

 tion in the amount and intensity of the rufous on the breast and lower 

 throat. The one female and one of the males (sex in quotation marks 

 on the label) have the rufous extending in diluted form up to the 

 chin. The light markings on the underparts vary from white to de- 

 cidedly rusty. The size variation is considerable, the wing length in 

 the males ranging from 161-187 millimeters, in the single female 

 examined, 164.5 millimeters; the tail 147-160 millimeters (males), 

 150 millimeters (female); the culmen 21-23 millimeters (males), 

 23 millimeters (female). All the males from Ethiopia are somewhat 

 larger than the one from Kenya Colony available for comparison, but 

 the difference between the latter and the smallest of the former is 

 very slight. 



CLAMATOR GLANDARIUS (Linnaeus) 



Cuculus glandarius Linnaeus, Syst. Nat., ed. 10, vol. 1, p. Ill, 1758: N. Africa 

 and S. Europe. 



Specimens collected: 



Male, Gato River near Gardula, Ethiopia, April 20, 1912. 



The single specimen collected is in immature plumage, having the 

 crown and nape blackish, the chin, throat, and breast ochraceous yel- 

 low, and the primaries rufescent. " 



This species occurs throughout Africa and all of southern Europe 

 east to Persia. Throughout its extensive range it varies greatly in 

 size but the variations appear to be wholly individual. Grant *^ 

 measured a long series of specimens and found that the breeding 

 birds of southern Europe and Asia averaged larger than those of 

 South Africa, but the overlapping was too extensive to warrant sub- 

 specific separation. More recently Meinertzhagen ** found that east- 

 ern breeding birds (Sudan, Egypt, Cyprus, Syria, Palestine, Asia
