A LIST OF THE BIRDS OF PEGU. 189 
86.—-Hydrocissa albirostris, Shaw. (142.) 
Very common and generally distributed. 
87.—Rhyticeros undulatus, Shaw. (146 dis.) 
I enter this on the authority of the late Marquis of Tweed- 
dale, who states (Ibis, 1877, p. 296) that Capt. Ramsay procured 
a young male at Tounghoo. Ihave never met with it. 
88.—Rhyticeros subruficollis, Bly. (146 ¢er.) 
Occurs from Pegu to Tounghoo along the valley of the 
Sittang. It is very abundant. This Hornbill feeds on snails 
a good deal, in search of which it spends much time. Near 
Myetkyo, at the head of the canal, twenty birds may be seen 
at one time hopping about those portions of the plain where 
the grass islow. They are in the habit of flying every day 
over exactly the same line of route, and they are not to be 
frightened from this procedure. When I began constructing 
the lock at Myetkyo I noticed. great numbers of Hornbills 
passing low overhead every morning. They kept to this 
route the whole time the lock was being built, regardless of 
the noise made by a large number of men and two pumping 
engines. 
89.—Paleornis indoburmanicus, Hume. (147 quat.) 
A very common species throughout the plains. I do not 
think it frequents the higher hills, 
90.—Palexornis torquatus, Bodd. (148.) 
As common as, or perhaps commoner than, the preceding. 
Also confined to the plains. 
91.—Paleornis cyanocephalus, Lin. (149 dis.) 
Like the two preceding Parrots, the present one is very 
numerous in the plains. 
92.—Paleornis finschi, Hume. (150 dis.) 
The birds I formerly procured on the Pegu hills were so 
dirty and imperfect that Mr. Hume was unable for certain 
whether they belonged to schisticeps or jinschi. As Capt. 
Ramsay’s specimens from the Tounghoo hills were identified 
by Lord Tweeddale with finschi, it is probable that the 
Pegu hills birds belong to the same race. I found it com- 
mon in the large forests on the hills between Thyetmyo and 
Tounghoo,
