 p. 325, "Panay"(1876). 



[Dinagat, <3 , June.] 



A single example, hardly separable from Zebu individuals, and 

 agreeing with them in dimensions, consequently larger than Luzon 

 and North-Mindanao specimens. Wing 3 - 66 inches, as against 

 2-95 ; tail, 3-00, as against 275.

xx. p. 536, $ (1 Dec. 1877). 



[Dinagat, $ , June : iris dark-brown ; bill blue tipped and 

 margined black ; interior of gape yellow-green ; orbital ring light 

 green ; legs grey blue.] 



2 . Azure. Feathers of the head grey at their insertion, and 

 each tipped with glistening azure ; a lengthened occipital crest 

 similarly marked. Space before the eye and lores pale blue. Chin, 

 cheeks, throat, sides of neck, and upper breast rich velvety turquoise- 

 blue, darker than the blues of the rest of the plumage. Back and 

 upper tail-coverts with grey bases to the feathers, the extremities 

 being blue, which is paler on the upper tail-coverts. Wing-coverts 

 of the same shade of blue as the head. Quills dark brown externally, 

 margined with a paler shade of blue. Lower breast, abdomen, vent, 

 flanks, and under tail-coverts white, tinged with pale greenish blue, 

 most intense on the flanks. Axillaries grey, tinged with pale blue. 

 Rectrices above like the quills ; underneath dark brown like under 

 surface of the quills. Shafts of the rectrices brown above, almost 

 white underneath. Shoulder-edge blue. 



Wing 2-82 inches, tail 3-00, tarsus 0-62, culmen 0"56. 



A form nearly allied to H. azurea, but differing in its lengthened 

 crest, its paler tints of blue, and in the absence of any black mark- 

 ings. The blue shade of the throat and upper breast is about equal 

 in tint to that of the predominant colour of the older known species.
