 males W. 138, 135, T. 122, 122. 



Mi. Kloss' two specimens from S.E. Siam listed by me 

 had the wing about 139. All these birds may be considered as 

 belonging to the above cited northern race, which differs 

 merely in size from birds from the south of the Malay Penin- 

 sula which for the present may be taken as representing true 

 C. vittatus (typical locality Java) the colour distinctions noted 

 by Gyldenstolpe in his single specimen occurring in both forms 

 indifferently. The dimensions of the southern birds in the 

 F.M.S. Museums from localities ranging from Kuala Selangor 

 to the extreme south of the Peninsula are wing. 127-132 or a 

 mean of 128.2 for eight specimens while the wing of the 

 northern form as indicated by the specimens quoted above 

 ranges from I 35-142 with a mean also for eight specimens of 

 138-2 mm.

It is very unusual to lind barbets frequenting even the 

 larger islands near the coast of the Malay Peninsula and the 

 occurrence of this species at Pulau Lontar was therefore a little 

 surprising. 



It seems hardly correct to rank this form from Sumatra 

 and the Malay Peninsula as merely a subspecies of C. fttligi- 

 nosus (Temm.) from Borneo, which differs so markedly in its 

 deep brick red throat, chin and upper breast, as some authors 

 have done. Malayan birds precisely agree with specimens from 

 Korinchi, West Sumatra, and it is difficult to credit Buttikofor 

 [Notes Ley den Mus. ix, p. 17 (1887) who seems to consider that 

 the two species are but plumage stages of one and the same 

 bird. Of the very large series of C. hayi from the Malay 

 Peninsula and Sumatra that have passed through mv hands 

 I have never seen one that could for a moment be confounded 

 with C. fuiiginosus, while the same is true of the series of 

 C . fuiiginosus before me, when compared with C. hayi. 



Immature birds have the throat and lower surface washed 

 with pale sulphur yellow and the tips of the median wing 

 coverts rufous buff. The bills are black in the males and 

 brownish horn in the females.
