Mr. Buxton's series consists of three males and two females. 
These last are undistinguishable from Javan (P. concretus $ ) 
and Malaccan examples in the plumage of the female. One 
male is adult, and is identical with adult males from Malacca— 
that is, with the crest on the crown of the head deep crimson, 
he postoccipital crest-plumes being dark greyish olive. A 
second example, that of a young male, has the whole of the 
crown and all the crest-plumes dingy reddish buff or yellowish 
red. The third is intermediate, the coronal plumes being 
almost all pure crimson, and the postoccipital plumes passing 
over from the reddish tawny colour to olive-grey. I possess 
Malaccan skins which match these three Sumatran males. 
In all the under surface is dark olive-grey. The coronal 
plumes in other Malaccan examples of young males are ruddy 
buff, while the elongated occipital crest-feathers are all flame- 
red, with a yellowish buff shaft-line and tip to each plume. 
In another Malaccan male the postoccipital plumes are 
dark greyish olive, while the coronal feathers are mixed bright 
crimson and pale ruddy buff. 
The adult male of H. concretus (Reinw.), ex Java (PI. Col. 
90, f. 1), differs from H. sordidus by having the entire crest 
crimson, although not of so dark a shade as in H. sordidus. 
The occurrence of this species beyond Java rests on no good 
authority. It is figured by Malherbe (Picidse, t. 41, f. 5) 
under the title of Micropicus kartlaubi. The curious fact 
that in H. sordidus <£, when immature, the whole crest 
is buffy flame-coloured (anyhow the postoccipital crest)—-
