ing with the yellowish on the basal portion of the bill; cere and 
skin round the eye chrome-yellow; iris deep brown; legs bright 
chrome-yellow, with black claws. Stomach empty. In the 
membranes that enclosed the air-cavities over the kidneys were 
two or three long and a few small whitish ascarides ; the largest 
measured about 11 in. long by ^ in. broad. 
This bird, like the Amoy variety, is rather darker on the upper 
parts than the generality of European Peregrines ; but its under 
parts are very pale, and only scantily spotted and barred with 
black. Mr. Gurney considers ours identical with the European 
bird.

Almost every country has its Kestrel; and where it occurs, it 
is generally the commonest of all Falcons. In Formosa this rule 
also obtains. One could seldom take a long walk without ob¬ 
serving a Windhover or two, so frequently true to its provincial 
name. At Tamsuy, on the top of the old square-built Dutch fort, 
which has stood the wreck of time for the last two centuries, a 
pair of Kestrels made their home. Wandering about the face 
of the country during the day, in the evening they were regular 
in their return; and we were sure to see them, just as it began to 
grow dark, drop carelessly into one of the banyan-bushes that 
spring from the sides of the fort, and quietly disappear for the 
night.

A fine female of this Eagle was brought to me at Tamsuy, on 
the 25th of March, from the interior. It had been shot while 
seated on a rock near a large pool; and from this it was wrongly 
inferred by the hunter that it was a Fish-Hawk. I learnt from 
the Chinese that it not unfrequently occurred on the hills, and 
that it preyed on hares and even occasionally on young deer. 
Mr. Gurney agrees with me in considering our bird identical 
with that figured in the ‘ Fauna Japonica 3 under the above 
name. I received the bird the day after it had been skinned, 
and was thus enabled to make the following note :—length 2 ft. 
4 in.; wing 1 ft. 7 in.; tail 12 \ in., of twelve feathers, somewhat
