As far as I can see the Ashy Drongos inhabiting Siarn ought to be referred to thc 

 race described by Lord Walden under the above-mentioned name. 



As compared with a series of B. c. cineracea Horsj. from Java, the Siamese birds 

 are at a glance distinguished by their paler underparts and their larger bilis. The upper 

 parts of the body are also slightly paler, especially the crown. The Siamese specimens 

 ha ve their lores blackish which is also a point of characteristic to B. c. mouhoti. 



From B. leucogenys Wald. they differ by having the under wing-coverts very dark 

 and without the white edges, which are very conspicuous in that form. Its nearest ally 

 is B. c. nigrescens Oates. but it is separated from that species by its much paler colouring.

Several distinct races ha ve been described of this bird. The form inhabiting North- 

 ern Siarn cannot be the typical Dissemurus paradiseus Linn. because of its enormous 

 crest and its long hair-like f rontal plumes. In one of my specimens the longest crest- 

 feathers are 45 mm. The form described by Linn^tjs has a very small crest and the size 

 of the bird is rather small. This race inhabits Java, the Malay Peninsula and probably
