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 Mivornis and then leading into Alcippe. In the genus Mix- 
ornis, however, the nostrils are oval and exposed whereas in 
Stachyridopsis they are covered with a membrane somewhat as in 
the two preceding genera.
