1918.] recently collected in Siam. 79 



I have not burdened this paper with much local 

 synonymy, and only a few references will be found to 

 publications dealing with other countries, but which 

 elucidate points of interest. Count Nils Gyldenstolpe, 

 who writes very happily in Eiiglish, has given a list of 

 papers dealing with Siamese birds in the repoi't on his 

 last collections (Kungl. Sv. Vet.-Akad. Hand). Ivi. No. 2, 

 p. 4, 1916). To these I would add ' Stray Feathers/ to 

 which direct application should be made by anyone working 

 on Siamese birds : seen through the medium of Gates or 

 Blanford, or the ' Catalogue of Birds/ the value of their 

 contents cannot always be appreciated. 



With regard to the methods of taking some of the 

 measurements, it may be well to say that the total length 

 (T. L.) is taken after the specimen has been well suppled 

 and straightened out, but not unduly stretched ; that the 

 tail (T.) is measured from the angle between the bases 

 of the inner pair of feathers to the tip of the longest 

 feather ; and that the wing-length (W.) is the distance in 

 a straight line, taken on the inner side with a graded rule, 

 between the anterior bend of the wing and the end of the 

 longest feather : the wing is not flattened in any way, and 

 the measurement is nearly always a chord. 



With regard to the individual dimensions given : to the 

 first specimen mentioned belongs the first measurement of 

 each kind, to the second bird the second measurement, and 

 so on throughout. The measurements are in millimetres.
