“Tris dark, bill yellow, black on culmen, 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 Perlis and from Langkawi 
and Terutau. All adults have the pale white spots on the wing 
coverts present though in a varying degree, these being hardly 
discernible in one bird from P. Lontar. They are also present 
in most immature birds which entirely Jack 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. temmuncki, which has a very wide range in contin- 
ental India, ranging south to Aracan and Burmah and M. 
eugenit, which does not seem to be known West of the Salwin. 
If the locality of the specimen of M. crasstvostvis 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, \/. dicrorhynchus, Salvad. is met with in 
the south of the Malay Peninsula and in Sumatra.
