me by Mr. Burbidge, and obtained during his recent expedition
to this mountain. The latter gentleman is well known
from his successful botanical researches on Kina Balu; and
I shall shortly lay before the Society an account of some
of his ornithological discoveries in the Sulu archipelago.
The present collection, though small, is of some importance;
and the character of some of the birds seems to show that the
mountains of Borneo, when thoroughly explored, will produce
many species akin to those found in the mountains of Java,
Sumatra, and even of the Himalayas.

The constant character of the long thin bill in specimens from
N. W. Borneo impresses me with the idea that Lord Tweeddale is
right in keeping C. tenuirostris distinct from C. enca, with which I
united it in my “ Catalogue of Birds ” (vol. iii. p. 43).

The first occurrence of this species in Borneo was recorded by me
in my list of Governor Ussher’s Sarawak collection ; but it cannot
be uncommon in North-western Borneo, to judge from numerous
specimens which have been sent from Labuan and from the opposite
coast by Governor Ussher and Mr. Treacher. Two specimens are
contained in the collection made on Kina Balu by Mr. Burbidge.

An adult and young bird, in Mr. Treacher’s collection.
This is an interesting addition to the avifauna of Borneo, and
seems to indicate an entirely new species. I t bears considerable
resemblance to C. bimaensis of Timor and Lombock, but differs in
having the long silky plumes on each side of the lower back black
instead of greyish white ; while the Timor bird has not, like G. borneensis,
any long hair-like plumes on the head. On the other hand
the latter character allies it to G. pectoralis of the Sulu Islands ; but
it may be recognised on comparison by the much smaller and more
metallic spots on the throat and fore neck, which are steel-green as
also are the neck-hackles. In G. pectoralis the spangles are large,
