Mr. R. Swinhoe on Formosan Ornithology. 
prescribed time of stay is as nearly a month as possible. The 
small party that annually visit this wood appear to come from 
the interior to recruit their strength and recover their feathers, 
and then to pass southwards. In Hongkong and Macao I found 
the same species as a summer resident only. In Formosa it oc¬ 
curred as an abundant summer resident on the plains about 
Taiwanfoo; but both specimens I procured were females. Un¬ 
fortunately, the only male I procured at Amoy was so shattered 
that I threw it away, and I have reserved no note of it; but I 
have adult females and immature birds from that locality, which 
in most respects agree with those procured in Formosa. The 
Formosan bird is, however, smaller, much paler, and less dis¬ 
tinctly spotted, and may perhaps be ranked as a variety. 
$, procured at Apes' Hill, in November. Length 9J in.; wing 
7y^-; tail 4^. Throat with two large white spots. A large 
spot of reddish white on each of the first three quills, occupying 
both webs in all except the first quill. Head spotted with black. 
A rufous collar extends from shoulder to shoulder. Wing- 
coverts and breast marked with large spots of clear rufous buff. 
Middle tail-feathers with nine bands of black. Tarse almost 
entirely naked, except at the tibial joint. Trachea in. broad, 
composed, near the lower larynx, of very thin close rings angu- 
lated downwards; the lower larynx not covered with muscle. The 
sterno-tracheal muscles, on giving off, become large and fleshy, 
and increase in bulk towards the coracoids. Heart in. long by 
Liver, right lobe 1 in., left X. A mass of yellow fat covered 
the belly. (Esophagus hard, X in. broad; proventriculus granu¬ 
lated, X long, ovate, X at greatest diameter. Stomach 1 ^ in. 
long, 1 broad, deep, ovate, and compressed; its tendons large 
and its sides hard and muscular ; epithelium thick and ochreous 
brown, broadly and deeply furrowed with longitudinal rugae, 
well distended with remains of Coleoptera (chiefly Cetonia ) and 
of nocturnal Lepidoptera. Ovary with numerous small eggs. 
Oviduct thin and black, ~ in. wide and li long, leading into the 
cloaca, proving that the bird was a mature female. Caeca 1 X in. 
from anus; right one li long, left one IX, both terminating in 
large black sacs, — at widest part, their stems being -X long by 
r V thick. Intestine 9 \ in. long, varying in thickness from X to T 3 _.
