ference of the eye; the tail is moderate and’plane, and the tarsi with- 
out spurs; the principal character, however, consists in the absence 
of the thumb nail. 
There is only one species well known, the male of which has 
a long tuft of slender red feathers, and long upright filaments, 
without barbs on each eye- -brow. It is the Rouloul de Malacca, 
Sonner. Voy. II, pl. 100; Cr ipt. coronatus, Tem., Col. 350 and 
3513; Columba cristata, Gm. and Lath.; Phastanus cristatus, 
Sparm., Mus. Carls. III, 64. Green; Some wit larger than a 
Quail. The female, which merely has a vestige of a tuft, is the 
Tetrao viridis, Lath., Syn. II, pl. 67.(1) ; 
TeTRAO, Lin.’ 
This also is a great genus, characterized by a naked and most gene+ 
rally red band, which occupies the place of the eye-brow.. It is di- 
vided into subgenera as follows.

il (The Great Heath- Geick. ) The largest of all the ‘Gilisthces, 
and superior in size to the Turkey. Its plumage’ is slate- 
coloured, transversely and finely striped with black; the female 
is fawn-coloured, the cross lines brown or blackish. Found in 
the heart of mountain forests, builds among the heath-grass, or 
\ in newly cleared grounds, and feeds on berries and buds. Its 
| trachea makes two curves before it dips into the lungs. The 
. flesh is delicious.

Naum. Ist Ed., 18, f. 37 and 38. (The Black Cock.) The 
male is more or less black, with some white on the coverts of 
the wings and under the tail, the two forks of which diverge 
laterally. The female is fawn-coloured, transversely striped 
with blackish and whitish. Their size is that of the Cock, and 
they are found in mountain forests. 
(1) The* Columba cristata, B., Gm., Lath., Syn. I, pl. lviii, appears closely 
allied to it; but the figure represents it as having a large nail to the thumb. This 
is perhaps an error, as in the Galer. Vieill, tom. I, ‘pl. cex.
