that the passage alluded to shows that Sir Thomas Browne was fully 
aware of the distribution of the feathers in well-defined regions, 
and that these differed in position and extent in different birds. 
Moreover, I believe the passage in the ‘ Ameenitates’ shows

of Mammals, mostly small, made by him in the Egyptian Soudan 
in the course of 1902. Among these no less than five prove to 
need new names, thus showing how much still remains to be done
