102 NJLS GYLDENSTOLPE, ZOOLOG1CAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 



It most probably belonged to the race, nained C. m. querulus by Heine. This race 

 inhabits the Eastern Himalayas, Bengal, Assam, Burma, Tenasserim, Siarn, Southern 

 China and Hainan and has been recorded once before from Northern »Siarn, (vide: Gyl- 

 denstolpe, Siarn. Journ. Nat. Hist. Soc, Vol. I No. 4). 



Specimens from the Malay Peninsula are almost intermediate between typical 

 C. m. merulinus Scop. and C. m. querulus Heine.

 black. Bill: black. Legs: black. 



The Cuckoo Drongo seems to be fairly rare in Siarn 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 Siarn. 



As shown by Stresemann (Novitates Zoologicse Vol. 20. p. 341, 1913) the Cuckoo 

 Drongos from Sikkim, Assam, Burma, Tenasserim, Southern Shan States, Hainan, Sze- 

 schuan and Siarn are larger than specimens from Sumatra, Borneo and the Malay Penin- 

 sula and ought to be referred to the race described by Hodgson as Surniculus dicruroides 

 which has the underparts of the body darker and more glistening than specimens from 

 the latter localities. 



The typical race 8. lugubris Horsf. inhabits Java and Ceylon while the race from 

 Sumatra, Borneo and the Malay Peninsula has been named S. 1. 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 Aving measuring 133 & 122 mm. resp. and the tail 

 144 & 132 mm. resp. 



196. Hierococcyx sparverioides. Vig. — The Large Hawk-Cuckoo.

The Large Hawk-Cuckoo was rather rare in the parts of Siarn visited duringmy 

 journey and it was only confined to the Northern and Central parts of the country where 

 it is a resident. It frequents thin tree jungle and was never observed in evergreen forests. 

 In the Siamese Malaya it was ttevér mel with though it at least oceurs as far south as 

 Bangkok from where it has been recorded bv Wtlliamson.
