ish-yellow. Inside of mouth bluish flesh-colour; apical half of 
tongue horny and of a pale yellowish-blue. Iris deep yellow. 
Naked feet bright orange-yellow or golden, and covered with black 
bristles; claws black, paler at their bases. Proved to be a female 
by dissection; fat and greasy. Stomach full of remains of Me- 
lolonthce and other insects, chiefly Coleoptera. 
“ Euplocamus swinhoii, Gould. I have seen many males with 
a plumage intermediate to that of the adult of their own sex and 
that of the females. This plumage is carried through the winter; 
but it varies in its resemblance to the one sex or the other. I 
thought at first that such birds were melanite varieties, especially 
as the Chinese distinguished them by a distinct name, Aw-hay- 
kak (black-tailed male); but I consider now that they are only 
young males in the transition-plumage, which they carry till the 
next vernal moult. In this respect they would appear to differ 
from the true Phasiani, which burst full-blown into the adult 
costume at their first moult in the autumn after they appear in 
the world.” 
Now I will drop Tamsuy and the past and speak of this vi¬ 
cinity and of my late acquisitions. From the southern moun¬ 
tains I received, in December 1865, a new species of Titmouse 
of the Parus major, L., type, and closely allied to Parus rnonti- 
colus, Vigors, of the Himalayas. It is a very lovely species. 
Parus insperatus, sp. nov. 
Similis P. monticolo, sed minor; uropygio cinereo nec dorso con- 
colore ; axillaribus, tibiis crissoque albis, nigro variis; 
collo sub gutta alba nuchali postice flavo. 
Long. tot. 4*5, alse 2*6, caudse 1*8 poll. 
Habitat in montibus Formosse meridionalibus. 
Head, sides of neck extending to back, under neck, and me¬ 
dian line of under body blue-black, with purple reflections on the 
three first. Cheeks, nuchal spot, broad tips to primary coverts, 
axillaries, half of under wing, outer side of tibiae, and broad tips 
to crissum white. Below the nape-spot and under parts fine

Rump and flanks bluish-cinereous. Primaries blackish brown,
