" Their flight is almost noiseless, with none of the metallic clang so conspicuous in that of
li. undulalus and subruficollis nor has it the swish of R. cavatus, Shaw, or B. rhinoceros. In
iact, it is just like that of U. (ij/lnis, malabarie-us, or It. 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 llight of all these is comparatively noiseless, you still can, when sufficiently close,
detect the sound of their wing, unlike Ji. coniatus, whose flight is utterly noiseless, almost
owl-likc,
'' They are strictly arboreal in their habits, never descending to the ground as does comatus
and the small hlaek-billcd U. nigrirosiris, Blyth, of the Malayan peninsula, which is generally
considered the female of the much larger and white-billed R. malaycma, but which wo never met
^vith in company with any white-billed specimens.
"This species is, we believe, strictly frugivorous; the only specimen whose stomach we
disscicted contained only fruit. Of course many Ilornbills, like B. comatus for instance, are quite
oiimivorous; wc have taken both lizards and birds out of the stomach of these; but we are inclined
to think that it is chiefly the spccies that habitually descend to the ground that feed in this fashion,
and galerituB 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 line fresh
specimen of an adult male:—
" Length 33-0, expanse -IG-T^, tail from vent 13-0, wiagl4i'25, tarsus 2-0; bill from gape 5-75,
from posterior margin of casque along ridge and culmen to tip 6-75; of casquc only, ; height of
upper mandible and casque at centre of casque l-<l-6, of upper mandible at the same place 079;
weight 2-5 lb.
" The legs, feet, and claws were black ; the irides lake-red ; the bill entirely black. Gular
and orbital skhi 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,"
3fale.—Bi\\ black. At a pouit about the centre of the maxilla a casquc slopes gradually
upwards from the culmen and inclines backward to the head. Tliis 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 gi-een,
the feathers very light along their edges. Wings have the secondaries bronzy green, edges whitish,
llest of body light brown, the edges of many feathers buff. Tail is bluish white for two thirds of
its Icuiith from tli« base, rest dark green. Iris lake-red. Eyelids mottled with black and white.
Feet greenish grey.
Ijcngth 35 inchcs, wing I t, tail 13, tarsus 2, bill casque 3^; height of bill and casque 2J-.
Precisely like the male, with the exception of the casquc and bill, which are shorter
aiul smaller, and the bare skin on throat, which is yellow.
Wiug 12* inches, tail 11|, tarsus bill
