THE WOOD-PARTRIDGES. i'j'j 



Adult Male. — Also very closely allied to C. oculea, but the 

 mantle is very black and sharply defined from the chestnut of 

 the crown and nape, the co?icentric white lines are narrower 

 and more regular than in typical C. out lea from the Malay 

 Peninsula, and the throat is darker and more rufous-chestnut. 



Range. — Mount Dulit, Sarawak, North Borneo. 



The only known example of this extremely handsome species 

 was obtained by Mr. C. Hose in the month of May on the moss- 

 clad summit of Mount Dulit, at an elevation of 5,000 feet.
