d-n. 6 ¢. Ho Ho Mt., 5000 ft., Feb., March 1906. 
Adult. Iris dark brown; bill black ; feet vermilion. 
In the immature bird the feathers on the top of the head 
are very distinctly spotted with black at the tip and have a 
subterminal light brown band (in the adult these markings 
are nearly obsolete); the median secondary-coverts are 
spotted with buff at the tip of the outer web; and a number 
of the breast-feathers are spotted with white at the tip of the 
shaft, like the flank-feathers. The bill is very much slighter 
than in the adult and is, moreover, differently coloured ; the 
iris is light greyish brown ; the bill reddish, black at the base 
and vermilion at the tip. 
The Formosan Tree-Partridge is peculiar to the mountains 
of the interior of the island.
