LONG-TAILED POLYPLECTHON. 
cimen was about eighteen inches, and was received 
from the island of Sumatra. 
Two additional species are figured by Mr Gray, 
in his Illustrations of Indian Zoology, but without de- 
scriptions. These figures are correct copies from 
the drawings collected by General Hardwick, and 
are tho work of native artists. The first, Mr Gray 
has dedicated to the General, Polyplectron Hard- 
wickii. It is nearly allied to the P. bicalcaratum. 
The ground colour of the plumage is ochrey yellow, 
with black spots and waves, the ocellated spots are 
surrounded with a black and yellow ring, and the 
head is furnished with a slightly bending forward 
greenish crest. Two of the dorsal feathers from each 
bird are also given ; the distinctions are, that of P. 
Hardwickii has a yellowish ground, with irregular 
black spots, that of P. bicalcaratum, darkish grey, 
with pale yellow spots. 
The other bird is named P. lineatum, apparently 
from a narrow pale line along the shaft of the fea- 
thers, particularly conspicuous on the rump. This, 
however, appears to me to be the young of some 
other species ; there are no spurs on the tarsi, and 
the description which Temminck gives of the young 
state of P. ocellatum, is near to the plumage of this 
bird. Our next illustration represents the genus Ar- 
gus of Temminck, containing a single species, which 
is
