To area 8 I have already referred with regard to its 

 species. Of the order of Passeres (i) — 45 genera 77 

 species — eleven genera and fifty species are not repre- 

 sented in area 9. Twenty-five per cent, of the passerine 

 genera of area 8 are not known in area 9,, 1 1 per cent, of 

 area 8 are not known in area i, and 33 i-3rd per cent, of 

 area 9 are not known in area 8. Althongh 75 per cent. 

 of the genera of area 8 are recorded as found in area 9, 

 it does not follow that they got into area 9 by means of 

 area 8, but rather that they emigrated into area 9 by 

 means of areas 6 and 7.
