‘‘ Male, iris inner ring blue, outer mauve, orbits smalt, 
bill smalt, bluish horn at tip, feet pinkish maroon, claws bluish 
horn.” 
“Female, iris inner ring blue, outer amethyst, bill and 
orbital skin smalt blue, feet pinkish maroon.” 
This pigeon takes the place of Sphenocercus oxyurus above 
about 6,000 feet, and is found almost as high as the limit of 
forest vegetation at 10,000 feet and over. It was met with by 
us in small parties of four or five birds and not in such large 
flocks as its congener, but this may be de to the fact that we 
discovered the feeding trees of the latter species, when the 
birds of course became more bunched. 
Owing probably to the high altitudes at which alone this 
bird is found the species appears to be decidedly rare in collec- 
tions and the present series is probably the largest from any 
one locality that has been examined by any ornithologist. 
It is evident that Salvadori is correct in regarding his 
S. etorques as only the sub-adult male, the rufous collar on the 
foreneck and the strong rufous tinge on the top of the head 
being only developed in very old specimens. ‘This is correlat- 
ed with a change in the colour of the under tail coverts, the 
longest of which are, in fully adult specimens, entirely pale 
chestnut, while younger birds have them paler cinnamon, with 
dark green centres to the feathers, which diminish in extent 
as the bird grows older. The maroon shoulder patch appears 
at a comparatively early age. 
In the female, old birds have the edges of the longer 
under tail coverts faintly tinged with pale cinnamon, but the 
centres of the feathers are always broadly olive green. 
Ogilvie Grant has described a species from the mountains 
of the Malay Peninsula as S. robinsoni,t comparing it with 
S. permagnus from the Liu Chiu Archipelago. 
From the material at our disposal, viz., one of the original 
typical series, a subadult male, three adults and an immature 
female, it is very doubtful if S. robinsont can be maintained, 
even as a subspecies, distinct from S. korthalst. 
The two adult females only differ from Sumatran speci- 
mens by slightly duller colour on the undersurface and by the 
more elongate and reduced olive green centres to the under 
tail coverts ; the subadult male can be almost perfectly match- 
ed by one from Sumatra ina similar stage, the edges of the 
under tail coverts being slightly more cinnamon. It is doubt- 
ful if fully adult specimens of the peninsular form have yet 
been obtained, but there is little question that when such are 
available, S. vobtnsont will have to fall as a distinct species. 
There is no difference in size between peninsular and 
Sumatran birds.
