OiNOPHILA, Stph. 
In some of the following species the frontal and occipital 
tufts are drawn together so as to conceal the fillet, but the 
structure of the head remains peculiar and characteristic, 
the lower part of face and back of crown being smooth, 
and the two tufts being really separate at origin. Besides 
the type-species, which is now common to Europe and 
Africa but probably originally African, and a second 
described form probably scarcely distinct, there are only 
three other species known, all from the Seychelles; the 
five now added are therefore in themselves a majority of 
the genus.
