228 Mr. C. Boden Kloss on Birds [I^^^' 



The males have the tail-coverts faintly tipped with whitish. 

 I have compared these birds with a recently collected series 

 of £. leucophaa [cinerea auct.) from Java and cannot detect 

 any differences. The colour is quite the same and, though 

 tlie Javan birds are smaller on the whole, the series yet 

 contains three equal in size to the Siamese.

Iris crimson or brown ; bill and feet black.

 36, 35. 



The type of Cuculus paradiseus Linn, came from Siam, and 

 these specimens may be regarded as practically topotypes. 



In the example showing greatest development of the crest 

 the length from the nostrils to the tips of the longest feathers 

 is almost equal to the length of the bill from gape ; when 

 pressed down the longest crest-feathers about 7'eacli the 

 occiput, while their greatest length from root to tip, when 

 straightened, is 33 mm. 



One rarely obtains truly adult examples of this Drongo, 

 but I regard as practically adult, birds having black abdomens 

 which show scarcely any white tips to the feathers there; as 

 subadult those in which the whitish tips are numerous; and 

 as immature specimens those in which the abdomen and 

 flanks are greyish. 



A crimson iris does not always seem to go with immacu- 

 late plumage, nor a brown one certainly indicate immaturity ; 

 only one of this series has the iris red, and the bird is con- 

 siderably more white-barred than are other sj)ecimens with 

 brown irides; its crest is also much smaller. 



* Founded on a crestless specimen, but Eaugoon birds have a ci'est 

 and are probably members of the present race.
