British Willow-Tits, but in their opinion it had so far been 

 much more important that they should be understood to be 

 specifically different from the ordinary Marsh-Tit with a 

 glossy crown. They could, however, corroborate the differ- 

 ences stated to exist by Hellmayr, though Mr. Hartert 

 would be quite content if more British ornithologists would 

 recognize the Willow-Tit as different from the ordinary 

 British Marsh-Tit, whether they called it Parus salicarius or 

 P. kleinschmidti, or adopted the trinomial name. Middlesex 

 and Sussex were the only counties where this form had at 

 present been detected, but it doubtless occurred in other 

 localities also. 



Dr. Bowdleb Sharpe described several new species of 

 birds from Africa, as follows : —
