$10 BIRDS. 
Only one species is known; of a bronze-brown above, whitish- 
grey beneath; top of the head red—Catraca, Buff.; Phasianus mot- 
mot, Gm., and Phas. parraqua, Lath., En]. 146*; Bajon, Cay. pl. 1. 
The cry of this bird is very loud, and articulates its name. The 
trachea descends under the skin as low as the abdomen, and then 
ascends to enter the thorax. 
With these different Hoccos naturalists usually associate the 
Ortstuocomus, Hoffmanseg.—Hoazin +, Buff. 
The Hoazin, an American bird of similar carriage, with a short and 
thick bill, the nostrils pierced in the horn, and destitute of membrane ; 
the head ornamented with a tuft ef long and very narrow and slender fea- 
thers, which is distinguished from all the true Gallinacee by having no 
membrane between the base of the toes. It is the Phasianus cristatus, 
L.; Enl. 357; Vieill. Galer. 193; greenish-brown, variegated with white 
above; front of the neck and (tip of the tail fawn-coloured; the belly 
chestnut. It is found perching along the margin of inundated places in 
Guiana, where it feeds on leaves and the seeds of a speciesof Arum. Its 
flesh smells strongly of castor, and is only employed as a bait for particu- 
lar fishes. 
Pavo, Lin. 
The Peacocks, so called from their cry, are characterised by an aigrette 
or crest on the head, and by the coverts of the tail of the male being 
larger than its quills, and capable of being erected so as to form a circle. 
The shining, lax, and silky barbs of these feathers, and the ocellated spots 
that decorate their extremities, are well known in the 
P. cristatus, L.; Paon domestique, Enl. 433 and 434. (The 
Common Peacock). A species in which the head is ornamented 
with an aigrette of vertical feathers widened at the tip. This su- 
perb bird, originally from the north of India, was introduced into 
Europe by Alexander. Its magnificent plumage is even surpassed 
in brilliancy by that of the wild ones. A rich blue supersedes the 
gold-green specks along their back and on their wings; their tail 
also is more plentifully furnished with feathers. 
The Pavo spiciferus, improperly styled by Linneus P. muticus, 
for it also has spurs, is a distinct species. The feathers of its ai- 
grette are long and narrow; its neck is not blue, but green, watered 
and gilt; the tail almost as magnificent as that of the common spe- 
cies}. Vieill. Galer. 202; Shaw, Nat. Misc.641. Another species. 
* N.B. The fig. in the Pl. Enl. is bad, inasmuch as it represents the tail pointed. 
+ This term was applied to the above bird by Buffon, without any proof, from an 
indication of Hernandez, Mex. 320, ch. 10. 
Vieill. Galer. 193, calls it Sasa cristata, and improperly represents the bill as 
notched near its commissure. Jt forms a genus very distinct from that of any other 
of the Gallinacez, and when its anatomy is known, may become the type of a parti- 
cular family. 
{ It was only known, for a long time, by a bad drawing from Japan, in the six- 
teenth century (Aldrov. IT, av. 33, 34), but Messrs. Duvaucel and Diard having sent 
several of the birds from Sumatra to France, M. Vieillot has given his figure from 
them.
