ETHNOLOGICAL NOTES.

It h as often been noticed that the Sea-Dayaks have 
a far richer vocabulary of natural history names than 
have the Malays and that individual Dayaks have a more 
accurate knowledge of, and greater power of discrimina¬ 
tion between, the different forms of animal and plant 
life with which they are indeed virtually brought up. In 
connection with this, it may be of interest to record 
that the Sea-Dayaks, besides using the general name of 
klabcmbang ( kcibumbang ) for butterflies and moths, have 
the special name of k'sulai for the skipper butterflies 
(Hcspevidae) and, by some Dayaks, for the swift-flying 
swallow tails ( Pnpilioninae ) as well. (The rich vocabu¬ 
lary of natural history names compared with that 
of more civilized neighbours has of course been noticed 
in many other primitive races besides the Dayaks, 
but illustrations of it are always of interest because 
the primitive daily merges into the next grade of the 
less primitive and so on along the dull marches of 
civilisation to the eventual complete extinction of all 
these little traces of natural * man).

Trengs. 
The Trengs were once a large and powerful tribe, 
probably at one time spread over that portion of the 
interior of Borneo where the big rivers, Rejang, Baram, 
Limbang, Kayan and Ivoti rise. Their descendants in 
Sarawak relate to-day how the Trengs once lived in the 
head waters of the Limbang, Madihit, Tutau and 
Baram. 
Carl Bock gives an account of some he met in Dutch 
Borneo, and among other things he notes that they are 
addicted to cannibalism.t Ling-Rothf barely mentions 
* Natural in the highest and best sense of the word, i.e , man conver¬ 
sant with all the ways and beauties of Nature, through long and intimate 
association with Nature herself, not by means of a knowledge obtained 
through the devious paths of literature.

214, 218, 221-222. 
Mr. Bock’s statement about cannibals is severely criticised by 
Messrs. Bampfylde and Brooke Low in the Natives of Sarawak and British 
North Borneo, by H. Ling-Roth, 1896, Vol. II , pp 222,223. The only 
" proof" of cannibalism that I came across among the Tabuns, was the 
presence of a human finger-nail attached to some charms on the belt of a 
Tabun chief!—J. C. M.
