the bill, about the eye, and on the belly of the other sex. In this 
species the trachea of the female is simple, but that of the male 
is terminated by large, swollen, convoluted bronchi. In a male 
specimen, procured in May, the bronchi ran down right and left, 
almost straight, for about 1 ^ in., then took a bend forward for 
a short space, and narrowed, and lastly, bending inwards and 
upwards, bulged largely, and entered into the lungs. The pro- 
ventriculus consisted of a large flabby sac, about 3 inches in 
length, and i n breadth in the broadest part, lessening to \ in. 
before it reached the stomach, which was round and muscular, 
yq in. in diameter, and supported by strong circular lateral ten¬ 
dons with radiating muscles. Both the stomach and the pro- 
ventriculus contained a thick greenish-yellow juice; the latter 
was stocked with remains of fish, and the former with numbers 
of small gritty stones, some as much as J inch in diameter. In 
both these were numerous small, thin Ascarides. Intestine 8 
feet long, and strong, averaging y 3 ^ in. in thickness. 
I kept four of this species, and two of the D. hrachyura , alive 
for some days in my verandah at Amoy, but could not get them 
to feed. The first few days they used to walk about in a clumsy 
manner, but afterwards they got weaker and could not manage 
to rise. Both species had a common habit of stretching the 
neck and raising the bill upwards, uttering at the same time a 
loud, hollow-sounded, moaning bellow, as of some animal in pain. 
The production of this sound seemed to force up oily matter 
into the mouth, for the birds would go through the movements 
of swallowing for some time afterwards. Through the day, and 
often in the night, this miserable moan would be uttered at set 
intervals. I kept one of this species alive, to see how long he 
would live without food, and he lived on, week after week, with¬ 
out. showing any particular signs of weakness, till about the 20th 
day. He then began to look shaky, but still obstinately refused 
to eat fish. On the 29th day he died: but his abstinence from 
food was in reality greater than that extraordinary number of 
days; for he had been in the possession of the fishermen who 
caught him nearly a week before he came to me. When fresh 
taken in the spring, the birds are particularly fat: but this starved 
specimen had survived on the gradual absorption of his adipose
