Mr. Gurney must have long ago received the pair from Tam - 
suy together with my descriptions, but I have not yet learned his 
opinion as to the validity of the species. I have followed the 
custom prevailing in this genus of naming the species after its 
local name. 
Besides the specimen procured near here (Takow) in January 
1866, I received in December 1865 an immature bird, also from 
the southern mountains. I now give the notes I have made on 
this. 
“ Spilornis hoya. Immature, from the Eungshan Mountains, 
procured November 1865. Length 28*5 inches; wing 19*3 ; 
tail 12*25 ; tarsus 4*4, feathered down the front for 1J ; middle 
toe 1*4, its claw *9; hind toe 1*1, its claw *1 ; outer toe smaller 
than inner, with small claw; inner toe robust, with claw as 
large as that on hind toe. Legs yellow, claws black. Crown 
and occiput white, tipped with blackish-brown; the occipital 
plumes much longer than in the adult. Moustache, eyelid, and 
auriculars blackish-brown. Tail with two brown cream-mottled 
cross bands about an inch in width, and indications of a third 
bar near its base hidden by the tail-coverts; rectrices tipped with 
cream-colour. Under tail black, the bars showing through 
brownish white; near its roots the under tail is barred and 
mottled with whitish. Under parts dingy cream-colour, streaked 
on the breast with blackish-brown, and more faintly on the flanks 
and abdomen. The vent and tibials washed with buff, and pret¬ 
tily barred with buff-brown shaded with black. Axillaries white, 
varied with reddish-brown. A good deal of white occurs on the 
underwing. On the primary and tertiary under-coverts the 
peculiar Spilornis -style of spots are showing themselves. Upper 
parts deep hair-brown, shot with purplish-pink; the feathers on 
their concealed halves whitey-brown,with more or less pure white. 
White margins to the higher tail-coverts, and brown to those in 
immediate proximity with the tail. All the small and large wing- 
feathers are more or less tipped with white, and some of the 
coverts are a good deal marked with it. Quills hair-brown, 
banded with blackish-brown, the latter showing through on the
