Genus STACHYRIDOPSIS Sharpe, 1883. 



This genus differs from the last in having the culmen perfectly 

 straight. It seems to be a form intermediate between Stachyris- 

 and Mix'ornis and then leading into Alcippe. In the genus Mix- 

 ornis, however, the nostrils are oval and exposed wiiereas in 

 Stachyridojjsis they are covered with a membrane somewhat as in 

 the two preceding genera.
