Over the whole of the extreme N.-B. of the Indian Empire, 

 throughout the western hills of the Assam Valley and Cachar, and 

 the Miri, Dafla and Sub-Himalayan ranges to the north of the Brah- 

 maputra, the grey-headed Flycatcher-Warbler cannot be said to be 

 either typical xanthoschista or jerdoni, and the birds of the Abor 

 Hills come, as might be expected, into the same category. The 

 three specimens as far as one can tell — one specimen has practicall}^ 

 no feathers on the head — in this collection are on the whole nearer 

 jerdoni than xanthoschista. The two sub-species are very close 

 together and the intermediate range over which the indefinite form 

 extends is greater than the two extremities over which one finds 

 specimens which are easily determined. The Kashmir and Hazara 

 birds appear to be all xanthoschista , and the birds of Eastern Assam,
