This species is strictly an inhabitant of evergreen forests : the 

 present bird is the northernmost recorded.

Malay States Mus. viii, pt. ii, 1918, p. 141 (Negri Sembilan). 

 Chotorhea chryso'po(j<in chrysojmijon, M., p. 429 (Peninsular Siam). 



Common in heavy jungle in Trang and Bandon, where it 

 attains its northern limit. 



There is no variation in this barbet through its range in the 

 Malay Peninsula. The mainland form is distinguished from the 

 typical Sumatran race by its deeper coloured yellow malar patches, 

 and from the Bornean Gh. cJtrysopogon chryso2)sis* by its larger 

 size, duller forehead without bright yellow tips to the feathers, and 

 paler ear-coverts. 



258. Chotorhea rafflesii rafflesii (Lesson).

 Megalaema versicolor, B., p. 74 (Coast adjacent to Junk Seylon ?) 



"Iris chestnut ; bill blacli, slatj'' at base ; feet greenish lead." 



This Gaudy Barbet is common in the interior of Trang, but is 



not recorded from further north than the vicinitv of Puket, whence 



Miiller obtained one example. 



Specimens from the whole length of the Peninsula, Trang, 



Perils, Kedah, Perak, Selangor and Paliang exhibit no differences 



inter se ; but we have been unable to compare them with typical 



Sumatran birds. Bornean birds, on the otlier hand, even when fully 



adult, have a paler blue superciliary stripe, and the quadrate yellow 



spot on the sides of the throat paler, less orange yellow, though, 



with Shelley, we can see no differences in the extent of the red on
