AND SPECIALLY THOSE OF THE THOUNGYEEN VALLEY. 159 



the highest trees. I described in a former article a nest and 

 eggs ; subsequent to that I managed to procure three nests 

 more on the 5th March ; out of these one contained four eggs, 

 one three and one two respectively. 



146 Us.— Rhyticeros undulatus, Shaw. 



I first found out that this species ranged much further north 

 than noticed by Mr. Davison, by obtaining a specimen on 

 the Zammee river, which was shot in the act of being fed. 



This, a young male with no trace of plications on the bill, 

 measured in the flesh : — 



Length, 43*0; expanse, 65-0; wing, 20-0; tail, 15-0; tarsus, 

 3'0 ; bill from gape straight to point, 7*2. 



Bill whitish green, reddish at base ; gular skin bright 

 chrome yellow with an imperfect band ; legs and feet black ; 

 irides yellow. 



Later on I found them abundant in the Thoungyeen forests,* 

 and took their eggs (S. F., Vol. VIIL, pp. 459-463.) Sub- 

 sequent to the taking of the one nest therein described, I 

 got two others on the 5th March, each containing two eggs, 

 and a fourth on the 17th of the same month, also with two 

 eggs, hard set. It is pretty clear therefore that the bird lays no 

 more than two. 



146 ter.— Rhyticeros subruficollis, Bly. 



This seems to me much more a bird of the plains and low 

 hills than the foregoing species. It is not very abundant in the 

 Thoungyeen, and I only got two nests, one on the 5th March 

 with two eggs, and the other on the 7th, with only one eg<r. 

 The three eggs measure respectively 2'22 X 1'63, 2'28 % 

 1-68 and 2'49 X 1'78. 



A very old adult female, shot 5th February 1887, measured 

 in the flesh: — Length, 33'0 ; expanse, 47-0 ; wing, 15"0; tail 

 from vent, 9*5 ; tarsus, 2'0 ; bill from gape, straight to point, 5'5. 



Bill yellow, red at base above ; gular skin purplish blue ; 

 irides red ; legs and feet black ; claws horny. 



147 quat.— Palaeornis indoburmanicus, Hume. 



This species I have never seen in the Thoungyeen valley, 

 and I do not think it crosses the Dawna range. About 

 Kaukarit on the Houndraw river, and again all up the 

 Salween as far as I have gone, it is common. 



* In S. F., Vol. VIIL, p. 459, in my " Notes on the Nidification of some Hornbills," 

 by a slip of the pen I stated in the second paragraph that R. undulatus was less 

 abundant than R. subruficollis; it is just the reverse; it is R. subruficollis that is 

 scarce in the Meplay forests, Of R. undulatus, I used daily to see large parties. —
