120. Penthoceryx sonnerati Latii. — During the whole journey in Siarn I 

 only got a single specimen of this Cuckoo from a native boy, who sliot a female in 

 a garden at Bangkok on the 30th of December 1911, so this species seems to 

 be very rare in Siarn. According to Blanford (Fauna of British India, Birds III, 

 p. 220) the range of the Banded Bay Cuckoo extends throughout Burma and the 

 Mahiy Peninsuhi to Sumatra, Borneo and Java but it is always rare. 



The specimen obtained has a wing of 100 mm. and the tail measures 105 mm. 



121. Eudynamis honorata L. — The Koel was heard several times in differ- 

 ent parts of the countiy, though it was most abundant in the evergreen forests of 

 Northern Siam, 



I was always unlucky in my efforts to get it and during tlie whole journey I 

 only got a male specimen shot in a forest close to Bång Hue Hom.

122. Rhopodytes tristis hainanus Hart. — This pretty bird was fairly com- . 

 mon everywhere in favourablc localities and was generally found över the whole j 

 country especially in thick bamboo jungles and secondary jungles. I often observed j 

 it mixed up among the flocks of the Laughing Thrushes and like these it excelled 

 in concealing itself in the thickets or moving silently among the branches. It was; 

 rather shy and wary but also very curious about everything. j 



Hartert has recently (Nov, Zool., Vol. XVII, 1910, p. 218) separated a form i 

 of Rhopodytes irisiis Less. which inhabits the Island of Hainan because of its smal-J 

 ler dimensions especially as concerns the wings which are measuring from 150 toi 

 160 mm. against 165 to 176 mm. in the typical Bhopodyies tristis. This recently i 

 described subspecies, Rhopodytes tristis hninann^ Hart, is also believed to inhabit 

 the neighbouring countries such as the French Indo-China and probably Siam.
