 " Iris dark, bill yellow, black on 1 ulmen, feet black." 

 Fairly common in heavy jungle on the hills, generally in 

 gullies and watercourses. 



There is great variation in the very considerable 

 number of adult specimens of this form now in the collection 

 from the mainland of Trang and Perils and from Langkawi 

 and Terutau. All adults have the pale white spots on the wing 

 coverts present though in a van ing degree, these being hardlv 

 discernible in one bird from P. Lontar. Thev are also present 

 in most immature birds which entirely lack the glistening 

 tips to the feathers above and are dull black beneath. 



There is considerable sexual variation in size, males being 

 much the larger. It is evident that the form is intermediate 

 between M . temmincki, which has a very wide range in contin- 

 ental India, ranging south to Aracan and Burmah and M. 

 eugenii, which does not seem to be known West of the Salwin. 

 If the locality of the specimen of M. crassirostris mentioned 

 by Gyldenstolpe, p. 62, viz., Java, is correct, I think that the 

 identification will have to be revised as the specimens would 

 almost certainly be referable to M. flavirostris, of which a 

 closely related form, M, durorhynclius, Salvad. is met with in 

 the south of the Malay Peninsula and in Sumatra.
