" Their flight is almost noiseless, with none of the metallic clang so conspicuous in that of 

 B. undulatus and subruficollis ; nor has it the swish of H. cavatus, Shaw, or B. rhinoceros. In 

 fact, it is just like that of M. affinis, malabaricus, or B. scutatus (Vigil) — a few rapid strokes of 

 the wing, a short sail with outspread wings, again a few rapid strokes, again a sail, and so on. 

 Although the flight of all these is comparatively noiseless, you still can, when sufficiently close, 

 detect the sound of their wing, unlike B. comatus, whose flight is utterly noiseless, almost 

 owl-like. 



" They are strictly arboreal in their hahits, never descending to the ground as does B. comatus 

 and the small hlack-hilled S. nigrirostris, Blyth, of the Malayan peninsula, which is generally 

 considered the female of the much larger and white-billed H. malayana, but which we never met 

 with in company with any white-billed specimens. 



"This species is, we believe, strictly frugivorous; the only specimen whose stomach we 

 dissected contained only fruit. Of course many Hornbills, like B. comatus for instance, are quite 

 omnivorous ; we have taken both lizards and birds out of the stomach of these ; but we are inclined 

 to think that it is chiefly the species that habitually descend to the ground that feed in this fashion, 

 and galeritus most certainly does not so descend, as, although able to procure but few specimens, 

 we saw the bird constantly, not only in Southern Tenasserim, but also at Kuroo, Nealys, Johore, 

 and other places in the south of the Malayan peninsula. 



" The following were the dimensions and colours of the soft parts recorded from a fine fresh 

 specimen of an adult male : — 



" Length 33*0, expanse 46'74, tail from vent 13*0, wing 14*25, tarsus 2*0 ; bill from gape 5*75, 

 from posterior margin of casque aiong ridge and culmen to tip 6'75 ; of casque only, 4*0 ; height of 

 upper mandible and casque at centre of casque 1'46, of upper mandible at the same place 0*79 ; 

 weight 2-5 lb. 



" The legs, feet, and claws were black ; the irides lake-red ; the bill entirely black. Gular 

 and orbital skin pale blue, darkest just in front of the eye, at the angle of the gonys and junction 

 with the feathers of the throat. Eyelids mottled black and white." 



Male. — Bill black. At a point about the centre of the maxilla a casque slopes gradually 

 upwards from the culmen and inclines backward to the head. This is highest at its anterior end, 

 and is black throughout. Bare skin around the eyes, and also on the cheeks and throat, pale blue. 

 Head covered with a long loose crest, which, together with the neck and mantle, is dark green, 

 the feathers very light along their edges. Wings have the secondaries bronzy green, edges whitish. 

 Rest of body light brown, the edges of many feathers buff. Tail is bluish white for two thirds of 

 its length from the base, rest dark green. Iris lake-red. Eyelids mottled with black and white. 

 Eeet greenish grey. 



Length 35 inches, wing 14, tail 13, tarsus 2, bill 5 -J, casque 3 J ; height of bill and casque 2-J. 



Female. — Precisely like the male, with the exception of the casque and bill, which are shorter 

 and smaller, and the bare skin on throat, which is yellow. 

 "Wing 12J inches, tail llf , tarsus 1-J, bill 4J. 

 Specimens described and figured are contained in the collection of the British Museum.
