18 BOOTED BEET) WARBLER. 



Hypolais. It is quite clear then that in the figure in my first edition, 

 copied from this specimen by Count Mlihle, the colours have been 

 slightly exaggerated. The strong affinities which Iduna salicaria has 

 with Hypolais elaica are manifest at a glance, but still the colours are 

 strongly pronounced and different in each. The beaks also differ, 

 being considerably more robust in elaica than in the present bird. 

 Its habits also decidedly place it among the Acrocephali, in which 

 class I have arranged it.
