NOTES ON SOME RECENTLY DESCRIBED SIAMESE BIRDS. 
By C. Bopen Kxioss, M. B. O. U. 
When I obtained the mammals with which I have just dealt, 
I also made a collection of birds of which I have given an account 
in “Ibis”, January and April, 1918. In the October number of the 
same Volume Mr. E. C. Stuart Baker criticised some of my conclus- 
ions and has repeated his views in his recent paper dealing with 
Mr. E. G. Herbert’s collection in this Journal (Vol III, No. 3, August 
1919, pp. 177-216), 
These notes are a reply to some of Mr. Baker's comments. 
While he seems to me to have proved a most successful discoverer 
of mares’-nests (in the matter of V. polioptera, O. f. minor, ©. s. 
koratensis, etc.), when I propose a really bad race he fails to 
convict me of error. Dicrurus annectens siamensis (Ibis, 1918, 
p. 226) now appears to me, with a good deal more material 
for examination and comparison, to be not only not a new form 
at all, but even to have nothing to do with annectens. It is 
merely Buchanga atra catheca (Swinh.) of S. E. China. The mat- 
ter will be dealt with later. 
Graucalus macei macei, Kloss, Ibis 1918, p. 192. 
Graucalus macei siamensis, Baker, Ibis 1918, p. 596; id. Journ. 
N. H. Soc. Siam, ITT, 1919, p. 208. 
My only specimen, being a male, could not be distinguished 
from the typical form; it is, of course, the bird since described as 
G..m. suamensis by Mr. Baker ( Bull. B. O. C., xxxviii, p. 69) on 
account of colour differences in the female. 
But is that name tenable? Baker himself says that the 
Siamese bird is the same as the Hainan one and the latter has 
already been separated by Hartert as Graucalus macei larvivorus 
[ Nov. Zool. xvii (1910), p. 227]. 
Volvocivora koratensis and V. polioptera, Kloss, t. c., pp. 193-4.
