Belonging to the group including D. ignipectus, from the 
Himalayan countries and the mountains of the Malay Penin- 
sula, D. sanguimolentum from Java and D. pygmaeum of the 
Philippine Islands. From the first two it differs markedly in 
lacking all red on the chest, in the absence of the glossy green 
black patches on the sides of the breast and in the reduction 
of the black median abdominal streak. 
From the latter it may be distinguished by having the 
lower back and rump glossy steel green, as the rest of the 
upper surface, not olive yellow. 
Adult male :—Whole upper surface steel green with violet 
reflections. Wing and tail black, the outer webs of the 
primaries glossy steel green, the tail feathers washed with 
metallic violet. Sides of the head and throat, ear coverts and 
a small patch on the sides of the breast, dark blackish grey; 
flanks and tibial feathers greenish olive. A median black 
patch on the abdomen; rest of the under surface buffy, pale on 
the throat and under tail coverts; quill lining and under wing 
coverts silky white; axillaries white, faintly tinged with buff. 
“Tris dark, bill black, feet brownish black.”’ 
Total length, 92; wing, 50; tail, 34; bill from gape, 10; 
tarsus, 14 mm. 
This little Flower-pecker is apparently rare, possibly 
because it lives in very high trees and is therefore hard to see 
and obtain, and though after the first one was secured it was 
hunted for assiduously, only the above series was collected. 
At first sight it might be considered that this species is 
merely an immature phase of D. ignifectus, which has not been 
recorded from Sumatra, or of D. sangwinolentum which has 
been attributed to the island on insufficient evidence, but 
we do not think that this is the case. The feet and bill, which 
is not orange at the gape, show that they are adult, which 
is additionally borne out by the highly glossy upper plumage. 
Of the sex there is no possible doubt. 
The birds named Dicaeuwm vanheysti are immature examples 
of this species. =
