114 Birds recently collected in Siam. [Ibis, 



size, but the tarsus and bill are a little longer ; the specimens 

 lent to me by the Calcutta Museum having wings 50, 50 ; 

 tarsus 13, 13 ; and B. f . g. 13, 14'5 ; and perhaps their 

 deeper colour is due to their sex or age as specimens, 

 the first having been collected in 1908 and the other by 

 Dr. J. Anderson.

These specimens and others I have examined from Siam 

 have broad oblique bars of white stretching from the quill to 

 the edge of the inner web on the three outer tail-feathers, and 

 represent Salvadori's malaccensis which seems sufficiently 

 distinct on this account for recognition. 



C. m. macrorhynchus (Gm.) came from Borneo, and the 

 white tail-feathers are either absent or only faintly indicated 

 by small spots on one or two of the feathers. Of C. m. 

 lemniscatus, the type-locality of which may be taken as 

 Bencoolen, Raffles wrote, '^ the tail is black'"'; but specimens 

 which I have seen from the Avest coast of Sumatra have both 

 white-spotted tails and tails with scarcely any white on the 

 feathers. All specimens, however, from the northern part 

 of the range of this species seem to have markedly white- 

 patched tails, and where the difference has become constant 

 it should be recognized.
