72 GYLDENSTOLPE, BIRDS COLLECTED BY THE SWEDISH ZOOLOGICAL EXPEDITION TO SIAM. 



Fain. Cicoiiidte. 



181. Dissura episcopus Bodd. — The White-necked Stork is very sparsely 

 distributed in Siarn, at least to judge from the few tinies I observed it. I once 

 saw a pair near a small pond-like lake east of Sakerat on the llth of January. Round 

 the town of Muang Pa (on the Korat plateau) are great rice-fields and a small river 

 runs through these and here I also saw two specimens. On the swamps at Tha 

 Law I also reeognized some White-necked Storks, but I never succeeded in getting 

 a specimen because the birds were very shy and wary. 



182. Leptoptilus dubius Gm. — The Adjutant was only observed twice during 

 my journey, but at both these places it seemed to be rather common, though very shy. 

 Round Tha Law I saw about 30 birds every day during my stay at this place. 

 The birds walked solemnly about on the big swamps, but when I tried to approach 

 they at once flow up in the bamboos round the marshes. 



Near the eastern coast south of Sriracha I also observed about a dozen birds 

 at the end of April 1912. 



Fain. Ardeidae. 



183. Ardea manillensis Meyen. — Very common round Tha Law but it more 

 often lived in places overgrown with high reeds than the other kinds of Herons, 

 This species was rather shy and by no means easy to get.

 Culmen = 125 » 

 Iris = yellow. 



184. Ardea cinerea L. — Our common Heron was also rather abundant on the 

 swamps round Tha Law, though it never occurred in sucli great numbers as Herodias 

 alba L. or Ardea tnanilleyisis Meyen. 



185. Herodias alba L. — The Large Egret was very abundant on the swamps 

 south of Pitsanulok in Central Siarn. On these it could be reckoned in hundreds 

 mixed up among the flocks of the other kinds of Herons, Storks and Ibises. I 

 also saw a few specimens along the coasts of the C4ulf of Siam, near the mouth of 

 the Menam Chao Phaya river. 



186. Herodias intermedia Blyth. — Among the Herons observed or collected 

 during my journey the smaller Egret was one of the most common. Several times
