38 MR. W. J. F. WILLIAMSON ON 
Iris dark brown. Bill yellow, tipped black. Legs deep 
yellow. Claws horn-colour. 
The only previous records appear to be those of Bonhote 
(P.Z.S., 1901, p. 80) and of Ogilvie-Grant ( Fasc. Malay., Zool. iii 
(1905), p. 119), from Patani, Peninsular Siam, in 1899 and 1901, 
respectively. 
*61. Anous stolidus (Linn.). The Noddy. 
3d, 12. Rocky islet near Koh Chuan, Inner Gulf of Siam, 
May 1918. 
Males. T.L. 427, 482,437 mm. W. 282, 280, 300. 
Female. T.L. 407 mm. W. 276. 
Iris very dark brown. Mouth and gape yellow, Bill black. 
Legs blackish brown. Claws black. 
The islet where these birds were obtained is a few miles south 
of Koh Chuan, in the Inner Gulf of Siam, and is an absolutely bare, 
low-lying rock, without the slightest sign of vegetation of any kind. 
It was absolutely swarming with terns (Sterna bergii, S. melanauchen 
and S. anaestheta ), all breeding, and among these the dark smoky or 
chocolate-brown Noddies were very conspicuous. They were also 
most extraordinarily tame, and I could have shot any number, but 
was content with four. The specific name is a very apt one, as the 
bird gives one the impression of being rather stolid and dull-witted. 
I was so fortunate, also, as to obtain two eggs of this species 
—each laid singly on a slight depression on the bare rock. 
Family SULIDM— Gannets. 
62. Sulasula (Linn.). Zhe Booby or Brown Gannet. 
1d. Rocky islet near Koh Chuan, Inner Gulf of Siam, May 
1918. 
T.L. 775 mm. W 400. 
Iris white. Bill pale bluish horn-colour. Pouch bluish slate. 
Loose skin at base of mandible yellowish green. Legs pale greenish 
yellow. Claws pale bluish horn. 
I have already recorded (Journ. Nat. Hist Soc. Siam, ii, p. 63) 
the finding of a sun-dried specimen of this bird on an islet near Koh 
Rin, in the Inner Gulf of Siam, in July 1916. On the present occasion
