the form of the casque is low, thinly compressed towards the front, 

 and abruptly truncate anteriorly, with a longitudinal ridge on each 

 side in old birds, occasioning a broad shallow groove above and 

 another below it. Length about 29 inches ; of wing 11 1- inches ; 

 tail to tip of middle feathers 13 inches ; to tip of outer feather 10^ 

 inches ; bill from gape 4| inches ; length of casque 3 inches ; height 

 from chin to top of casque 2^ inches. 



Mr. A. R. Wallace states, in a letter from Singapore (Ann. Nat, 

 Hist. Feb. 1855), that " B. nigi'irostris is the female oi B. malay- 

 anus, Raffles ; I satisfied myself of this fact from the dissection of 

 about a dozen specimens shot off the same tree." 



The bill and casque of B. malayanus are allied in form to the 

 corresponding parts of H. albirostris and H. convexus, Temm ; and 

 that of H. nigrirostris to that of the next species. 



We have described these birds as male und female on the authority 

 of Dr. Cantor.

Colour green-glossed black, with the basal two-thirds of the tail 

 drab-coloured, the wing-feathers slightly margined paler : head fully 

 crested, composed of broad longish feathers. Throat naked, or 

 merely showing two single rows of ill-developed feathers along the 

 middle. Bill and casque black in the one sex, which seems always 

 to have the abdominal region pale ; in the other yellowish-white, 

 with black along the summit of the casque nearly to the end, and 

 also occupying the basal two- thirds of the lower mandible, and the 

 tomise of the upper one, and, according to Dr. Cantor's MS. notes, 

 the "iris vandyke-brown ; naked space round the eyes, and pouch 

 black. Feet greenish-grey." The casque is low, and with a keel- 

 shaped ridge, sloping off to the front. 



" In a young specimen," remarks Mr. Blyth, " the plumage is 

 quite similar to that of the adult, but has no trace of casque, and the 

 bill is nigrescent with a whitish ridge and tip." 



Several specimens obtained at Malacca.
