Otocorys petrophila, Severtz. J.f. O. 1873, p. 379. 



Adult male. Similar to 0. elwesi and having the bhick of the ear- 

 coverts separated from the black of the fore neck by a white inter- 

 space, but differing in the shorter and stouter bill. 



The males have the culmen from 0-4o-0"o5 inch and the wing 

 4-0-4-G inches. In the females the culmen is 0-45-0-5 and the 

 wing 3-9o-4-l inches. The difference in size between the sexes is, 

 therefore, not so marked as in some of the allied species, and the 

 female seems to me to have more black on the crown than in 0. elwesi.
