secondaries becoming more and more cliestnut, the brown 

 being reduced to a mere tip or disappearing altogether. 

 Upper tail-coverts ultramarine-blue. Central pair of rec- 

 trices ultramarine-blue with black shafts, and slightly washed 

 with dull green, remainder black with deep blue outer 

 margins. Chin and middle of upper throat crimson with a 

 tinge of vermilion. Breast^ abdomen^ flanks, and under

Family Bucerotid^,

Pretty common everywhere. Goes about in small flocks 

 of three or four or more. Irides dark brown. Bare orbital 

 patch black. Contents of stomach : ants and other insects 

 and fruit-seeds. 



On several occasions I saw another small Hornbill similar 

 in size and general appearance to this species, but brown in 

 colour. I failed, however, to obtain specimens. It was 

 probably L. camurus (Cass.) or L. hartlaubi (Gould). 



Bycanistes cylindricus. 



One specimen obtained near Yonnibanna. On the Bumpe 

 E/iver I saw a number of Hornbills of, I believe, this species. 

 They perched on the tops of tall trees, and uttered a slirill 

 cry consisting of one syllable repeated six or seven times, 

 the head being gradually thrown back till the bill pointed 

 upwards. 



Family AlcediniDvE. 

 Ceryle rudis. 



Found chiefly along the sea-shore and in tidal inlets. Its 

 food consists entirely or principally of fish. 



Alcedo quadrihrachys. 



Never seen far from water. Is fairly plentiful in 

 mangrove-swamps and along the course of streams. 



Corythornis cyano stigma. 



Tills beautiful little Kingfisher is common along swamp}' 

 creeks and in mangrove-swamps.
