I find it impossible to discriminate between P. b. blanfordi and 
P. lb. vobinsoni. There is an immense series of this species in the 
British Museum collection containing the two alleged races, and a most 
careful examination of this material does not confirm the supposed 
differences when they are sorted out into geographical areas.

Mr. Herbert’s series of this Bulbul is quite typical, individuals 
varying in the same way and to the same degree as they do elsewhere. 
It is noticeable, however, that there are no specimens of M. (m) cin- 
ereiventris in Mr. Herbert’s collection. As a general rule where one is 
found the other is always also to be met with, almost invariably the 
two together in company, and [ believe the latter to be merely an 
Lo 
aberrant form of the former.

I cannot divide Hartert’s saturatior from typical frontalis. The
