This splendid Wood-Partridge was first described by Dr. 

 Bowdler Sharpe, from a single female specimen obtained by 

 Mr. W. H. Treacher near the La was River and now in the 

 Oxford Museum. In 1891 a second female was collected by 

 Mr. Hose on the moss-clad summit of Mount Dulit, at an 

 elevation of about 5,000 feet; but it was not until 18^3, when 

 Mr. Everett's collectors captured a third example of this rare 

 bird on the eastern slope of Mount Kina Balu, that the adiiU 

 male of this wonderful form of Partridge, with its brilliant 

 crimson chest and treble-spurred legs, became known. The 

 three individuals mentioned are all that have been obtained, 

 and the two latter now form part of the National Collection.
