[Nos. 1767-71, 1783, 1784. ] 
“Tris chestnut, bill slate, tinged with green, the nail black, 
tarsi and toes brownish green or greyish brown, the membrane 
darker.” 
Fairly common in the neighbourhood of Sungei Penoh, 
flying over the rice-flelds at dusk in small flocks of five or six. 
Exceedingly common. among the reeds and on the marshy 
ground at the north end of Korinchi Lake; not apparently 
extending very far up the valley as it was not met with at 
Siolak Daras. 
This Australasian Duck has apparently a wide extension 
of range along the chain of the Sunda Islands as it has been 
met with in crater lakes of Sumba, Sumbawa, Lombok and 
Java. The only other record from Sumatra is the lake of 
Alahan Panjang in the Padang Highlands, situated at over 
4,000 feet, where it was obtained by the Mid-Sumatran 
Expedition. This is its farthest westward and northern ex- 
tension. 
The series is very uniform, males and females are 
practically identical, the female being slightly smaller. Males 
have the wing about 255 mm. and females about 10 mm. less.

a. 16. Korinchi Lake, Sandaran Agong, Sumatra, 
2,450 feet. May 2oth, 1914. [No. 1752.] 
“Tris dark brown, orbital ring greenish yellow, bill slate 
grey, tarsi pale slate grey, toes and webs darker.” 
Said to be very common in the valley at certain times of 
the year, but not so at the time of our visit. 
The true Dendrocycna arcuata, which ranges from Fijias far 
west as Jaya has been doubtfully recorded frem Sumatra, but 
it is probable that all records of it should be referred to this 
western race, which has the upper tail coverts partially chest- 
nut and not mingled black and white.
