26 BIRDS OF THE LARUT HILLS. 
Tolerably common, from the low country up to 4500 feet. 
Blanford and other authorities say “ nidification unknown,” but 
I find in No. 24 of this Journal, p. 169, a nest and eggs des- 
cribed by Lieut. H. J. Kelsall, which are doubtless rightly 
attributed to this species. I have several times found nest-holes 
in banks in heavy forest which cou!d only have been those of 
this bird, though I never found one in use to settle the question. 
The note of this bird is extraordinary,.a very hoarse and loud 
‘ka-ka! ka-ka!”, which, until I found out the author of it, I 
thought must come from some sort of hornbill at least! (2) 
90,  Dichoceros bicornis. (Linn.) 
Tne Gieat Hornbill. 
I met with this grand Hornbill several times near the top 
of the Hill, but it was considerably scarcer than the next species. 
91. Buceros rhinoceros. (Linn.) 
The Rhinoceros Hornbill. 
The commonest large Hornbill 01 the bills, where their ex- 
traordinarily loud and discordant notes may be heard through- 
out the day at intervals. (3.) 
92. Anorrhinus galeritus (Temm.) 
The Bushy-Crested Hornbill. 
Not uncommon at 2000 feet and upwards. I have also 
met with it at Ginting Bedei and Bukit Kutu in Selangor, but 
not yet at less than 2000 feet elevation. This Hornbill is almost 
always in small flocks, which keep up a curious shrill call at in- 
tervals. It always reminded me forcibly of the chorus raised 
by a litter of hungry puppies whose mother has tantalized them 
by paying them a short visit and leaving them again! I found 
them shy and difficult to shoot, making off by short flights from 
tree to tree directly they were approached. Their habits 
seemed to me very regular, a flock visiting a particular tree 
just at noon for several days, until the fruit supply was exhaust- 
ed. (2.) 
93. Rhinoplax vigil. (Forster.) 
The Helmeted Hornbill.
