simply on account of its larger size. Specimens vary greatly ; and from the fact that as small ones 

 are fonnd among Deyra-Doon examples as are met with from other localities, I do not consider that 

 there are two species. With respect to this so-called species of Blyth's, Dr. Jerdon remarks (Ibis, 

 1872, p. 5), "this is the Gachar bird noted by Major Godwin- Austen in his list of birds as coronata. 

 His measurements quite agree with those of the next supposed species, H. affinis, Blyth, and confirm 

 me in my doubts as to this bird being distinct. My suspicions were aroused by observations in 

 the Dehra Doon, where I killed one or two individuals of the supposed species of much smaller 

 size, nearly corresponding with the dimensions of H. albirostris" Tickell says that this bird is 

 nearly omnivorous, but prefers fruit to other food. It breeds in Arakan and the Tenasserim 

 provinces in July or August ; and the female is stated to lay from two to four white eggs, in the 

 hollow of a tree, without any nest. 



Schlegel, in his catalogue of the birds of this family contained in the Leyden Museum 

 states that a skeleton of this species was obtained during the voyage of M. Diard, at Pontianak, in 

 Borneo ; and Mr. Low has sent it in a small collection of birds from Labuan. 



Bill and casque yellowish white ; base of casque, a broad patch at the anterior end of the 

 same extending onto the maxilla, and the base of mandible jet-black. Casque about equal in 

 height to the depth of the bill, narrow and sharp in front, swelling into a rounded form behind, 

 and extending over the head at a rather sharp angle. The casque in the male extends forwards, 

 following the line of the maxilla, and ends abruptly, being about a half inch in height [at its 

 anterior termination. The nostrils are set in a groove on top of the maxilla, at the junction of the 

 casque. Close to the base of the mandible is a bare flesh-coloured spot, and one behind the eye. 

 Head and neck, back, wings, and tail, except the tips, black with a bluish gloss. Underparts, about 

 two inches of the ends of primaries, and secondaries, except the uppermost ones, and ends of the 

 lateral feathers of the tail pure white. 



Total length 30 inches ; wing 11 ; tail 12 ; tarsus If ; bill along gape 6, length of casque 5, 

 height of bill and casque 3 J. 



The female is like the male in plumage ; but the casque does not extend so far forward on the 

 maxilla, and slants towards the culmen at a different angle from that of the male. Its anterior 

 portion, together with the tips of the bill, are black.
