There has been a good deal of activity during the last 

 few years in regard to the ornithology of Siam, and many 

 articles have been published in the recently established 

 Journal of the Siam Natural History Society. The results 

 of Count Gyldenstolpe^s first journey have already been 

 noticed in our pages ('Ibis,' 1914, p. 144). In his second 

 journey he visited the northern extremity of Siam, bor- 

 dering on the Shan States and the southern portion of the 

 country due east of Burmese Tenasserim, and he appears 

 to have obtained a fine booty. 



The number of species mentioned in his list, w'hich is 

 accompanied by field-notes and critical remarks on taxoiiomy, 

 is 353, and a good many of these are new to the Siamese 

 fauna. The new forms described are La?iius hi/poleucus 

 siamensis, Turdus aureus nnfjustirostris, Mixornis yularis 

 minor, Alseonax siamensis, Gerygone griseus, Picus vittatus 

 eisenhoferi, Picus canus hessei, Brachylophus chlorolophoides, 

 Sphenocercus pseudo-crocopus. With one exception the new 

 species have already been described in the Ornith. Monats- 

 berichte for 1916. Among the illustrations will be found 

 a sketch-map showing the route taken and the localities 

 where collecting was done, two coloured plates illustrating 

 the more important new forms discovered, and two plates of 

 photographs of types of scenery encountered. The intro- 

 duction contains a bibliography and an account of his 

 wanderings, and some reflections on the zoo-geographical
