The Booby is found in large numbeis 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 1901, 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 jNIuseum.

We saw a Darter on the freshwater lake in the Langkawis 

 (alluded to, ' Ibis ' 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 '^ Penang,''^ '' Province Wellesley," 

 "Malacca,'^ and '^ 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 ap})ear 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 Hivers by Aunandale 

 and Hubback {in litt.), but the observers were not ornitho- 

 logists and may possibly have confused it with the Fiufoot 

 [Heliopais personata) met with in these localities.]
