140 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 
& Hat Sanuk 94/1 1915. W = 496 mm.; T = 218 mm.; C = 155 mm. — Trides: bloody red. Bill: 
brownish black with red tip. Legs: dark red. 
In the »Notes from the Leyden Museum, Vol. 26, p. 154» Finscu has given a key 
to the four species or subspecies of the White-necked Stork. He gives the distribution 
of the typical Dissoura episcopus Bopp. to India, Burma, Cochin China, Ceylon and 
Malacca(? ). 
Its nearest ally is Dissoura neglecta Finscu. 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 Finscu. which 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 Koh 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. Laru. — The Black-necked Stork. 
Xenorhynchus asiaticus: Gairdner p. 30; Gairdner p. 152. 
This large Stork seems to be rare in Siam, and during my journey I only observed 
a few specimens on the swampy country outside Chieng Sen, the most northern town in 
Siam. 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. 
Leptoptilus argala: Schomburgk p. 267. 
& Chieng Sen 1%/s 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 over 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 Siam too, and on the 11th of October 1914 when going down 
the Meh Ping river I saw two specimens in the act of pairing. The female was sitting
