Northern Portion of the Malay Peninsula. 667 
though we secured examples of a new species of another 
genus of the latter group. 
At the time of our visit both islands were under the 
suzerainty of Siam, Langkawi belonging to the vassal State 
of Kedah, while Terutau was under Setul. The inhabitants 
of Langkawi were almost exclusively Malay, while those of 
Terutau were mainly Siamese, or rather Sam-sams, a mixed 
race of Malay and Siamese .origin, speaking the latter language. 
Both islands are visited during certain seasons by tbeOrang 
Laut, or Sea Gypsies, a people akin to, if not identic&l with, 
the Sellings of the Mergui Archipelago, who frequent the 
coast as far north as those islands. These people, however, 
are more commonly found on the Butang Group, which lies 
about twenty miles to seaward of Terutau and is otherwise 
uninhabited. We were not so fortunate during the brief time 
at our disposal as to meet with any of these interesting folk. 
Since the date of our visit Langkawi, as part of Kedah, 
lias passed under the protection of Great Britain by the 
Anglo-Siamese treaty of 1909, while Terutau, as an island 
frequented by Siamese-speaking people, 'still remains an 
intrinsic part of the Siamese dominions. 
We left Penang for Trang on November 25th in a small 
and crazy Chinese steamer, much overloaded with material 
for the railway now under construction from the port of 
Trang across the Peninsula to join the main line from 
Singapore to Bangkok, as provided by the Anglo-Siamese 
Treaty. After a brief stop at two small ports in the State of 
Perlis, Lunghu and Sungei Opis, which are mainly concerned 
with the shipment of pepper, we arrived at the mouth of the 
Trang Biver about 5 p.m. on November 26th. The navigation 
along this coast is exceedingly intricate, no charts being at 
present in existence, and within the last few months several 
wrecks have taken place, sunken rocks and shoals being very 
numerous. The scenery is extremely picturesque, as the 
course lies through an archipelago of lofty limestone islands 
of strange outline, covered with rich vegetation and fringed 
with white coral beaches. Arrived at the river's mouth, we 
promptly stuck on the bar, but as the tide was rising soon
