Crex (Crakes, &c.), to be succeeded by the handsome 
Porphyrios, of which there are several species, all 
bearing a strong family likeness, and known from their 
prevailing colour as purple, green-backed, grey-headed, 
and other Gallinules; they are very showy birds, and 
some species are occasionally kept in confinement. ‘The 
Australian Black-tailed Water-hen (Z77ibonyx ventralis) 
is an interesting bird, which leads on to the Gallinules 
proper, of which our Moor-hen may be taken as the 
type ; several species are here shown, one a handsome 
crested bird, G. cristata from India, and G. phenicura, 
a native of China. The genus sophia, which is 
represented by P. crepitans, the Gold-crested Trum- 
peter, a singular but handsome South American bird, 
brings the order to a conclusion. 
Order eleven, GALLIFORMES, is said to contain 
some 320 species; it is divided into two sub-orders, 
the first of which contains only one family, anda 
single species, the Hoatzin (Opzsthocomus cristatus), a 
very remarkable bird, which has been assigned an 
isolated position at the head of the Gallinacious birds. 
It inhabits British Guiana and the Valley of the 
Amazon, and appears to feed on leaves and fruit. 
The second sub-order, GALLIN2, commences with 
the Peacocks; there are two species, placed for con- 
venience in Case XV., although belonging here— 
Pavo muticus, inhabiting Burmah and Java, and 
P. cristatus, the common Peacock, a native of India, 
both birds of wonderful beauty, but so well known as to 
need no description. The Peacock Pheasant, Poly- 
plectron bicalcaratum ornaments the bottom of the case 
in company with the marvellous Argus Pheasant, Avgus 
giganieus, the beauty of whose ocellated plumage 
becomes more and more wonderful the more closely it © 
is examined. ‘The tail is very long, but is to a great 
extent hidden by the enormous extension of the wings,
