Genus 2, Polyplectron, Temm. 



Range. — From Assam, throughout Burmese countries, to Sumatra 

 and Borneo (?). 



1. Polyplectron CHiNauis. (Indian Polyplectron.) * 

 Polyplectron chinquis, Temm. PI, Col. 539. 



Hab. Assam, Sylhet, Arakan and Tenasserim, down to Mergui. 



This is the Pavo tibetanus of Linnaeus, but, not being found in 

 Tibet, cannot be called by that specific name. The best figure of 

 the male bird is given in the ' Planches Coloriees.' We received two 

 males of this species in 1857, presented to us by the Babu Rajendra 

 Mullick, which are still living in good health in the Gardens. The 

 same gentleman has again sent us a pair this year, but the female 

 unfortunately died before reaching England. There is, however, no 

 doubt that this fine bird would do well in captivity. 



2. Polyplectron BiCALCARATUM. (Hardwicke's Polyplectron.) 



Pavo bicalcaratus, Linn. 

 Polyplectron iris, Temm. 



Polyplectron hardwickii, Gray, Ind-. Zool. i. pi. 37. 

 Hab. Malacca, commonly received in collections of skins formed 

 in Malacca ; Sumatra {Raffles). 



3. Polyplectron CHALCURUM. (Sumatran Polyplectron.) 



Polyplectron chalcurum, Temm. PI. Col. 519. 

 Hab. Sumatra. 

 Mus. Brit. 



4. Polyplectron emphanes. (Napoleon's Polyplectron.) 



Polyplectron napoleonis, Less. Trait. d'Orn. p. 487 (desc. nulla). 

 Polyplectron emphanum, Temm. PI. Col. 540. 

 Hab. Perhaps Borneo. 

 Mus. Brit. 



Genus 3. Argus, Temm. 

 Range. — Malay peninsula, Sumatra, and Borneo. 



1 . Argus giganteus. (Argus Pheasant.) 



Phasianus argus, Linn. 



Argus giganteus, Temm. ; Vieill. Gal. pi. 203. 



Hab. Malacca, and northwards to Mergui {Blyth) ; Siam (Mou- 

 hot) ; Sumatra in the deep forests, generally in pairs (^Raffles) ; 

 North-western Borneo {Wallace). 



The Siamese and Bornean birds may probably constitute local 

 varieties. 



A second species of Argus {Argus ocellatus) has been created on 

 the faith of certain feathers in the French National Collection, but 

 the bird is otherwise unknown. See Bp. Compt. Rend. xlii. p. 878.
