1862.] MR. GOULD ON NEW BIRDS FROM FORMOSA. 285 
barred with buff ; lateral tail-feathers nearly uniform deep chestnut ; 
bill horn-colour ; space surrounding the eye and the legs red. 
Total length, 18 inches; bill, 11; wing, 8}; tail, 8; tarsi, 3. 
Remark.—This exceedingly beautiful species is one of the most 
remarkable novelties I have had the good fortune to describe ; in 
size it is somewhat smaller than the Genneus nychthemerus, which it 
resembles in its red wattles and in the form of its tail, while in its 
strong legs, the scaly stiff feathers of the lower part of its back, the 
red-and-white colouring of the anterior portion of its upper surface, 
and in its steel-blue crest it more closely assimilates, in my opinion, 
to the members of the genus Luplocamus ; and with that group, the 
Fire-backs, I have accordingly associated it. 
In dedicating this fine bird to Mr. Swinhoe, I feel that I am only 
paying a just compliment to a gentleman who must ever rank among 
the foremost of those travellers who have enriched ornithology by 
their numerous Eastern discoveries. 
Genus Bamsusicota, Gould. 
Generic characters.—Bill moderately long, and very similar in 
form to that of Perdix ; nostrils covered by an operculum; wings 
moderately long, round, and concave, the fifth primary the longest ; 
tail somewhat more lengthened than in Perdiz, rounded or inclined 
to a wedge-shape; tarsi rather long, and armed with a well-defined 
but blunt spur; toes longer than in Perdizx, the. two lateral ones 
equal in length, and united at their base by a membrane; hind toe 
rather long and free. 
Sexes alike, as in Caccabis, but the female destitute of a spur. 
This is a very distinct form among the Gallinacee, the species of 
which, so far as we yet know, are only two in number, namely, the 
present bird and the Galloperdix sphenurus of China. Both evince 
a predilection for forests of bamboo, which circumstance has suggested 
the generic appellation. In point of affinity they equally approach 
the members both of the genera Perdix aud Caccabis. 
BAMBUSICOLA SONORIVOX, Gould. 
Male: crown of the head rusty brown, each feather obscurely 
barred and freckled with blackish brown; lores, ear-coverts, chest, 
back of the neck, and chest grey, each feather minutely freckled with 
blackish brown ; back and rump olive, each feather minutely freckled 
with blackish brown; those of the back, nearest the mantle, largely 
blotched with deep chestnut ; these chest-marks also extend over the 
shoulders, near the tips of which is a lanceolate spot of white; a 
similar but more obscure mark also occupies the sides of the wing- 
coverts, but, instead of being white, it is pale fawn-colour; greater 
wing-coverts chestnut in the centre, then black, fringed with dee 
buff ; primaries blackish brown externally, margined with reddish 
chestnut ; two middle tail-feathers freckled brown, buff, and black ; 
the remainder deep chestnut-brown; abdomen rich cinnamon, with
