140 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 



J 1 Hat Sanuk 3l /i 1915. W = 496 mm.; T = 218 mm.; C = 155 mm. — Irides: bloody red. Bill: 

 brownish black with red tip. Legs: dark red. 



In the »Notes from the Leyden Museum, Vol. 26, p. 154» Finsch has given a key 

 to the four species or subspecies of the White-necked Stork. He gives the distribution 

 of the typical Dissoura episcopus Bodd. to India, Burma, Cochin China, Ceylon and 

 Malacca(?). 



Its nearest ally is Dissoura neglecta Finsch. from Java, Sumbawa, Lombok, Celebes 

 and the Philippine Islands. This species or rather subspecies is characterized by having 

 the sides of the head and a line down the neck from the ear-opening naked, while in the 

 typical Dissoura episcopus only the sides of the head are naked. 



During my stay at Hat Sanuk, a small creek running down from the Tenasserim 

 mountains on about Lat. No. 11° 50', I succeeded in shooting a fine male specimen of 

 the White-necked Stork. This specimen has a very pronounced area from the ear-open- 

 ing down the sides of the neck quite naked and on account of this it ought to be referred 

 to Dissoura episcopus neglecta Finsch. wliich certainly only is a geographical race of 

 D. episcopus. 



These Storks are very shy, and although I made several efforts to get some more 

 specimens I never succeeded. However, near Koll Lak they were not rare and I often 

 saw some specimens on a swampy plain near the sea-shore. They also seem to be found 

 at the small swampy pools so common in the evergreen forests along the Tenasserim 

 boundary. The specimen I obtained was shot in an almost dry creek. 



298. Xenorhynchus asiaticus. Lath. — The Black-necked Stork. 



Xenorhynchus asiuticas: Gairdner p. 30; Gairdner p. 152. 



This large Stork seems to be rare in Siarn, and during my journey I only observed 

 a few specimens on the swampy country outside Chieng Sen, the most northern town in 

 Siarn. On account of its shyness and its habit of keeping to almost inaccessible swamps 

 it is very difficult to obtain, and I never succeeded in shooting a specimen though I made 

 several efforts to get one of these beautiful birds. 



299. Leptoptilus dubius. Gm. — The Large Adjutant. 



Leptoptilus dubius: Gyldenstolpe I p. 72; Gairdner p. 30; Robinson & Kloss p. 16: Gairdner p. 152.

J 1 Chieng Sen *% 1914. L = 1310 mm.; W = 750 mm.; C = 285 mm. -- Irides: grey. Bill: dirty 

 brown. Legs: black. 



The Large Adjutant was fairly common at suitable localities över the whole coun- 

 try. It is, however, more common in the north and as far south as at about Lat. N. 12° 

 not a single specimen was observed. 



They probably breed in Siarn too, and on the llth of October 191-1 when going down 

 the Meh Ping river I saw two specimens in the act of pairing. The female was sitting
