The A. convexus was first separated from its relatives and described as distinct by Temminck 

 (I. c). It bears a very close resemblance in the colour of its plumage to the A. coronatus. In 

 fact, in this respect the two birds are precisely alike ; but there are differences, in the size and in 

 the shape and markings of the casque of this species, which, together with its habitat, seem to 

 point it out as distinct. It is a much smaller bird ; the casque is swollen and not nearly so much 

 compressed on the sides as that of A. coronatus; and the black mark on the casque reaches the 

 maxilla, which is never the case in its ally. It has received two or three names besides those 

 hestowedby Temminck; and some writers have called it by both Gmelin and Shaw's names, 

 confounding it with the A. malabaricus. It has a fair distribution, being found throughout the 

 Malayan peninsula, in Sumatra, and also at Labuan, where it was procured by Messrs. Motley and 

 Dillwyn— who state that it is not uncommon, but shy and wild, going usually in pairs and keeping 

 in the deep and tall jungle. Their food is almost entirely fruits, although in captivity they will 

 eat any thing, but were especially fond of plantain. According to the Malays, they frequent the 

 beach in search of small fish. Mr. Motley's captive birds were fed on boiled rice made into balls ; 

 but on one occasion they swallowed some ducklings that incautiously came within reach of their 

 bills. The voice is a harsh and discordant croak, and is stated to sound something between the 

 the bray of an ass and the croak of a landrail ! Besides Labuan, this species has also been procured
