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. of this Journal, p. 169, а 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 could 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.) 
The Great 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 on the hills, where their ex- 
traordinarily loud and discordant notes may be heard through- 
out the day at intervals. ) 
92. Anorrhinus galeritus (Temm.) 
The Bushy-Crested Hornbill. 
Not uncommon at 2000 feet and upwards. I have also 
Kutu in Selangor, but 
This Hornbill is almost 
. 
pproached. Their habits 
; a flock visiting a particular tree 
, until the fruit supply was exhaust- 
seemed to me very regular 
just at noon for several days

93. Rhinoplax vigil. (Forster.) 
The Helmeted Hornbill.
