164 LONG-TAILED POLYPLECTRON. 



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 the work of native artists. The first, Mr Gray 

 has dedicated to the General, Polyplectron Hard

 The ground colour of the plumage is ochrey yellow,

 greenish crest. Two of the dorsal feafhers from each 

 bird are also given ; the distinctions are, that of P. 

 Hard wickii lias 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
