Numerous off Langkawi in November 1907. 
The Booby is found in large numbers throughout the 
Straits of Malacca south to Singapore, but, at any rate on 
the western side, is seldom seen near land. It breeds on a 
small rocky island, one of the Aroa group, in mid-channel 
between the coast of Selangor and Sumatra. Near Pulau 
Jarak, in December 1904, one actually flew under the thwarts 
of our boat in the early morning and being a fine adult 
specimen was duly enshrined in the Selangor Museum.

We saw a Darter on the freshwater lake in the Langkawis 
(alluded to, 4 Ibis 9 1910, p. 664), but it kept to the middle of 
the lake, and having no boat we were unable to secure it. 
We are quite at a loss to know where the specimens in the 
British Museum from 44 Penang,” “ Province Wellesley,” 
44 Malacca,” and 44 Johor ” really came from, as it is highly im¬ 
probable that they were derived from the localities ascribed 
to them. The Hume collectors do not appear to have come 
across the species, nor have we met with it ourselves in over 
seven years, and there are no local specimens in any of the 
Malayan Museums. It has been uncertainly recorded from 
the headwaters of the Perak and Pahang Bivers by Annandale 
and Hubback (in litt.), but the observers were not ornitho¬ 
logists and may possibly have confused it with the Finfoot 
(.Heliopais personata) met with in these localities.]
