There is a singular conformation in the trachea of several of them. 
They live in the woods, feed on buds and fruit, perch and build on 
‘trees, are very social and easily domesticated. Gmelin and Latham 
have divided them into Hoccos and Yacous, but upon very undeter- 
minate characters. We subdivide them in the following manner. 
Tue mye: properly so called, Buff.—Mirovus, of Brazil, &c.— 
Crax, Lin. 
Have a strong beak, its base surrounded with a skin, which is 
sometimes highly coloured, in which the nostrils are pierced; on 
the head is a tuft of long, narrow, erect feathers, curled at the 
tips: They are the size of Turkeys, and like them fly up into trees. 
They are bred by the Americans; and individuals are sometimes sent 
tc Europe, so variously coloured, that we are at a loss how to cha- 
racterize their species.» The most common, or 
Crax alector, L.; Mitou-Poranga, Marcegr.; Buff. Ois., II, pl. 
xiii; Vieill. | Galer. .» 199. Black; the lower part of the belly 
white; cera of the beak, yellow. The trachea makes but one 
6 slight curve before it enters the thorax. * Some of these birds, 
such as 
Crax. globicera, L., Enl. 86; Edw., 295, 1, have a larger or 
smaller globular tubercle on the base of the ee Among both 
of these species individuals are to be found in which the body is 
irregularly striped with white or fawncolour. Albin., IT, 32.(1) 
The whole upper part is sometimes fawn coloured.(2) Those of 
Peru, 
Craz rubra, L., Enl. 125, are all of a vivid chesnut colour above, 
the head and neck being variegated with black and white.(3) 
Ourax, Cuy. 
The Pauxi(4) have a shorter and thicker beak, the membrane of its 
base, as well as the greater part of their head being covered with 
a short and dense plumage resembling velvet. The most common 
species, 
Crax pauxi, L.; Pierre, &c.3; Enl. 78; Vieill. Galer. 200 (The 
Stone Bird), has an oval tubercle on the base of its beak, of a

(2) Such is the female described by Azzara, Voy. IV, p. 169. From the ac- 
counts of other travellers, it appears that the females, also, are fawn coloured.
