102. NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 
It most probably belonged to the race, named C. m. querulus by Herne. This race 
inhabits the Eastern Himalayas, Bengal, Assam, Burma, Tenasserim, Siam, Southern 
China and Hainan and has been recorded once before from Northern Siam. (vide: GYL- 
DENSTOLPE, Siam. Journ. Nat. Hist. Soc., Vol. I No. 4). 
Specimens from the Malay Peninsula are almost intermediate between typical 
CG. m. merulinus Scop. and C. m. querulus HEINE. —

black. Bill: black. Legs: black. 
The Cuckoo Drongo seems to be fairly rare in Siam and only one specimen was ob- 
tained near Ban Meh Na, a small village situated at the foot of the Chieng Dao mountain 
in Northern Siam. 
As shown by STRESEMANN (Novitates Zoologice Vol. 20. p. 341, 1913) the Cuckoo 
Drongos from Sikkim, Assam, Burma, Tenasserim, Southern Shan States, Hainan, Sze- 
schuan and Siam are larger than specimens from Sumatra, Borneo and the Malay Penin- 
sula and ought to be referred to the race described by Hopson as Surniculus dicruroides 
which has the underparts of the body darker and more glistening than specimens from 
the latter localities. 
The typical race S. lugubris Horsr. inhabits Java and Ceylon while the race from 
Sumatra, Borneo and the Malay Peninsula has been named S. I. brachyurus by STRESE- 
MANN. 
The relative length of the wing and the tail in two specimens from Java among the 
collections of the Royal Natural History Museum of Stockholm does not quite agree with 
the measurements given by STRESEMANN (tom. cit. p. 340) as seen by the measures taken 
on our Javan birds which have the wing measuring 133 & 122 mm. resp. and the tail 
144 & 132 mm. resp.

The Large Hawk-Cuckoo was rather rare in the parts of Siam visited during my 
journey and it was only confined to the Northern and Central parts of the country where 
it isa resident. It frequents thin tree jungle and was never observed in evergreen forests. 
In the Siamese Malaya it was never met with though it at least occurs as far south as 
Bangkok from where it has been recorded by WILLIAMSON.
