Bill, etc., precisely as in the naale. 



140,— Dichoceros cavatus, Shaw. 



This Hornbill is very abundant in the Thoungyeen valley. 

 Near Gatai on the Hteepoyo choung in the Meplay, in February 

 1880, I saw enormous numbers collected on four or five fig 

 trees that happened to be in fruit at one time. 



I have taken several of their eggs, and have nothing to 

 add to my account of their habits and nesting (S. F., Vol. 

 VIII., p. 461.) 



142.— Hydrocissa albirostris, Shaw. 



A very common bird in the Thoungyeen valley. Sub- 

 sequent to the taking of the two nests, as described in 

 my paper above referred to, I had marked down for me 

 and procured three more nests on the 5th March 1880, of 

 which one contained a single egg, and two, two eggs each. 

 The mode of nidification, etc., was, in the case of this as well 

 in that of the different Hornbills referred to below, precisely 

 as described in my former paper. 



I give the dimensions taken in the flesh of an old adult 

 female caught off one of the nests on the 5th March : — 



Length, 27'0; expanse, 34*0; wiug, 10*2; tail from vent, 

 irO ; tarsus, 1*7 ; bill from gape straight to point, 4 # 3. 



Bill yellow, shaded with black on the fore and hind portions of 

 the casque, on the fore part of the upper mandible and tip, and 

 edges of both ; just in front of the gape on the bill there 

 is a reddish patch ; the legs and feet are dusky plumbeous 

 black ; the irides reddish brown, and the bare skin of the face 

 livid white, tinged blue. 



144 bis.— Ocyceros tickelli, Blyth. 



It is strange how tame this Hornbill is during the breeding 

 season, ordinarily, (and I have come across flocks of it on the 

 hio-h hills, between the Zammee choung and the Hound raw 

 river, on the ranges near the Sal ween, and in various places 

 on the Dawna and its spurs, from the head waters of the 

 Thoungyeen to its mouth, i.e., from Mooleyit to the Salween,*) 

 it is the wariest of the wary, keeping well above the tops of 



* I have boon assured by Karens that this species occurs much further north in 

 the Bceling hills.— C. T. B.
