In the collection there are five specimens of this small and plain-coloured bird, all 
obtained in the hill-forests at Koon Tan. 
Like other members of the present family this Flower-pecker was mostly seen in the 
clumps of the parasitical plants growing on other trees. The Plain-coloured Flower- 
pecker is probably fairly common in the Northern parts of the country, though it very 
easy escapes notice on account of its small size and plain-colouring. 
A near relative Dicewm minullum, Swinu. inhabits the island of Hainan. It is 
smaller than D. m. olivacewm but has, according to HarTeErt, a brighter colouring on the 
upper surface, especially on the head. The flanks are also more yellowish olive and the 
bill is decidedly larger. 
Another allied form D. solicitans Hart. inhabits Java where it seems to be rather 
rare. In the collections of the Royal Natural History Museum of Stockholm there are 
two specimens of this bird, which exactly agree with the description in the literature.

A single male specimen of Hume’s Flower-pecker was obtained among the Koon 
Tan Hills. 
Both in size and colouration it is very similar to Piprisoma squalidum Burton. 
which also inhabits the Burmese countries. It is, however, according to SHARPE, sepa- 
rated from this last-mentioned form by having the four outer tail-feathers tipped with 
white while in P. squalidum only the two outer tail-feathers are tipped with white.

Apparently a very rare species. 
Nuthatches were only observed in the deciduous hill-forests of Northern Siam and 
they were always very scarce except Dendrophila frontalis Swatns. which was rather com- 
mon in suitable localities. 
The Cinnamon-bellied Nuthatch was, however, also obtained by me during my pre- 
vious Expedition to Siam 1911—1912. Outside Siamese Territory it inhabits the Hima- 
layas, Assam, Manipur and Upper Burma.
