APPENDIX. 
Of 37 species peculiar to the island, 4 only have their generic allies confined to the Philippines ; 
4 others are forms distinct from those of either the Malayan or Philippine regions. 
The Malayan forms predominate by 36, as against 19 from the Philippines ; but there is a curious 
absence of several weak-winged Malayan genera, such as Trogons and Barbets, in the list. The Timeliine 
birds are all peculiar to Palawan, and the two Pittas arrive from the Philippines ; so that if there ever was 
any connexion between Palawan and Borneo, or with any other Malayan territory now more remote, it 
must have existed for only a short period of time. As yet, I believe, no species of Merops has been met 
with in Palawan, which is curious, as in the large adjacent islands this genus is very plentiful. 
The species in the following list peculiar to Palawan are marked thus f. 
Migrants *. 
P. = Philippine region only. 
M. = Malay region only. 
1. CACATUA HiEMATGROPYGIA (L. S. Mull.). P. 
Common ; generally met with in pairs ; has a slow flapping flight, and often screams when on the 
wing. During the heat of the day Cockatoos rest in the shade high up in the trees, where they carry on 
their flirtations, screaming and erecting their crests and performing many antics. Towards evening they 
flv in flocks to the rice-fields, doing much harm before the harvest. 
Eye black, orbit white ; bill pale blue, white at the tip ; feet dull blue. Sulu, “ Agi.” 
2. Tanygnathus leuconensis (L.). P. 
Very common. This Parrot is one of the first birds that attract the traveller’s attention in Palawan, 
as it flies swiftly from forest to forest in small flocks, screaming loudly. In flight the wings are often 
kept much below the level of the body. This species frequents the tops of high trees, feeding on various 
jungle fruits, but often during the heat of the day they hide amongst thick-foliaged trees only a few feet 
from the ground, from which they dash out with loud screams when disturbed. 
Bill rosy red ; feet horny green ; the pupil black, with a small black ring round it. 
3. Prioniturus cyaneiceps, sp. n., Sharpe, t- 
Similis P. ctiscuro, sed pileo toto et cervice cum capitis lateribus viridi-cyaneis ; gutture toto, pectore 
et abdomine viridi-cyaneo lavatis. 
Adult male. General colour above grass-green, becoming clearer green on the lower back and rump, 
and decidedly brighter on the upper tail-coverts ; curious dusky frecklings are seen on the feathers in a 
strong light ; wing-coverts green, the median and greater coverts a little brighter ; bastard-wing and 
primarv-coverts green, with a bluish tinge internally ; quills black, externally green, subterminally with a 
blue shade, and fringed with yellow, the first primary externally blue ; two centre tail-feathers brio-ht 
green, with a black shaft and racket at the end, which is black edged with green : remainder green, 
internally blue, and with a broad band of black at the ends ; tail blue underneath ; entire head and nape, 
as well as the sides of the face, ear-coverts, cheeks, throat and sides of neck verditer-blue, overspreading 
the under surface of the body, which is otherwise light green, but yellow towards the vent and under 
tail-coverts, the latter being yellow washed with green ; under wing-coverts and axillaries bright green ; 
lower primary-coverts and inner web of quills pale blue, blackish externally and at the tips of the 
primaries. Total length 12 - 4 inches, culmen 08, wing 6T, tail 2‘8, long feathers 5'6, tarsus 05. 
Young birds differ from the adult in being entirely green, without any of the beautiful verditer-blue 
shade on the head and neck ; the wing-coverts and secondaries edged with yellowish green ; under surface 
of body pale green, yellower on the throat, and bright yellow on the under tail-coverts, washed with pale 
green. 
This beautiful little Parrakeet is nearly as common as the last species, but it was some time before I 
could make them out to be different birds, owing to the swift flight of both species ; then, again, the 
curious racket tail-feathers were not visible, nearly all the birds being in full moult. In August,
