16 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 



these gentlemen were of utmost value for the succesfull carrying out of my plans and 

 without their help the results of the Expedition would ha ve been nothing of what they 

 have turned out to be. To the Siamese Government I owe letters of introduction to the 

 officials in the different Provinces through which I had the pleasure of travelling. 

 Without such letters of introduction travelling in Siarn is very difficult and almost im- 

 possible but with them a journey in the wilderness is fairly easy. The Government also 

 furnished me with an escort of some Gendarmes when I went through the more uncertain 

 parts of the country. 



Several other persons and some of the large firms such as the Bombay, Burmah Trad- 

 ing Corporation and the Borneo Company Limited helped me in several ways which 

 help was most valuable. 



To the Siamese Government and then principally to H. R. H. Prince Damrong 

 of Siam and the Vice-Minister of the Ministry of Interiör H. E. Phya Maha Ammat as 

 well as to other gentlemen and officials both mentioned and unmentioned I herewith 

 want to express my utmost gratitude. 



In the systematic list the following abbreviations are used: 

 L= total length (measured in flesh.), 

 W = length of wing, 

 C = length of culmen. 

 B = bill from gape. 

 T = length of tail. 



Fani. Corvidae. 



1. Corvus macrorhynchus. Wagl. — The Jungle Crow. 



Corvus culminatus: Scliomburgk p. 252. 



Corvus macrorhynchus: Williamson I p. 42; Williamson II p. 76; Barton p. 105; Robinson & Kloss p. 71; 



Grant p. 66; Gyldenstolpe I p. 18; Gyldenstolpe II; Gyldenstolpe III p. 164; Robinson II p. 150; 



Gairdner p. 148; Robinson III p. 761. 



The Jungle Crow is commonly distributed över the whole of Siam and does not 

 avoid even the dense forests, though it is most abundant in or around towns and villages. 



Mr. Stresemann has kindly informed me in a letter that the Siamese Jungle Crows 

 probably belong to the race which has been described by Adams (Proc. Zool. Soc. 1859 

 p. 171) under the name of Corvus intermedius founded on specimens from Kashmire and 

 Simla. This race according to Stresemann »seems to be of much the same colour as 

 typical C. macrorhynchus which, howewer, always have the bases of the feathers pure 

 white, while in C. intermedius they vary from pure white to påle grey. Young birds in 

 their first plumage have the bases of the feathers brownish grey. The bill in C. intermedius 

 is also somewhat differing from that one of C. macrorhynchus. In the first-mentioned 

 form the bill is generally shorter and lower and the highest point is not at the base but 

 at about the nasal opening».
