Mr. It. Swinhoe on Formosan Ornithology. 
cyaneous, blackened on sides of the neck. Lores and space 
round bill black. A few of the feathers of the frontal portion of 
the supercilium white on their apical halves, forming a partial eye¬ 
brow. Under parts ferruginous-buff, olivaceous on the flanks, 
and white on the middle of the belly and on vent. All the under 
feathers with their basal or concealed halves dusky plumbeous. 
Tibiae dusky. Quills deep hair-brown, edged with light reddish- 
brown and olivaceous; winglet deep blackish-brown; coverts the 
same, edged with dusky cyaneous, and occasionally with reddish- 
olive; tertials margined beneath with pale ferruginous. Tail 
blackish, margined with dusky cyaneous; all the rectrices, except 
the middle pair, having more or less pure white on their basal 
third, which is concealed by the upper tail-coverts, and only ap¬ 
parent when the tail is expanded. Tail 1*5 inch long, of twelve 
nearly equal mucronate feathers. Wing 2*3 inches long; the 
fifth quill slightly longer than the fourth, and longest; first quill 
small and narrow, *75 inch shorter than the second, which is *3 
inch shorter than the third, the latter being T inch shorter than 
the fourth. Whole length of bird 3*8 inches. Tarsus *7 inch. 
Outer toe longer than the inner. The stems of the soft cyaneous 
upper feathers are whitish on their basal or concealed half. Axil- 
laries mottled with a little of the ferruginous breast-colour. 
This species resembles most S. superciliaris , Blyth, but is to be 
distinguished from it by its black face and sides of the neck, and 
by the white base to most of its rectrices. It has also characters 
in common with the other three species, S. strophiata , Hodgs., 
S. leucomelanura , Hodgs., and S. erythaca } Blyth. 
On the 8th of February I received a fine specimen of a female 
Astur (Lophospiza) trivirgatus. Length 16*25 inches; wing 9 
inches; tail 7*6 inches. First quill 1*5 inch shorter than the 
second, which is more than *8 inch shorter than the third, which 
is *3 inch shorter than the fourth and fifth, the longest in the 
wing. The second to the fifth quills indented on the inner web, 
the first less sinuated. Tail of twelve nearly equal feathers; 
rectrices barred, the outer pair with only one faint bar near the 
base and an indistinct one near the tip. Legs yellow, claws 
black. Tarsi about 2*75 inches long, feathered for about 1*75 
inch down the front; middle toe without the claw about 1*62
