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 shins which match these three Sumatran males. 

 Iij 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 ^. 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 hartlaubi. The curious fact 

 that in H. sordidus ^ , when immature, the whole crest 

 is huffy flame-coloured (anyhow the postoccipital crest) —
