5. Notes oil Specimens in the Hume Collection of Birds 

 By R. BowDLER Sharpe, F.L.S., F.Z.S., &c.— No. 6 ' 

 On some Species of the Genus Digenea. 



[Received April 3, 1888.] 



When arranging the Muscicapidce belonging to the Hume Collec- 

 tion, I laid aside a specimen belonging to the genus Digenea, which 

 a|)peared to me to be new to science, but which 1 did not like to 

 describe from a single skin. In the Tweeddale Collection, however, 

 I have found another example, and it is so evidently distinct that I 

 no longer hesitate to give a name to the species. 



Digenea leucops, sp. n. 



Adult. General colour above light olive-brown, with somewhat of 

 an ashy tinge ; wing-coverts like the back, the greater series some- 

 what more ruddy brown externally ; bastard-wing, primary-coverts, 

 and quills dusky brown, externally ruddy olive ; upper tail-coverts 

 rather more reddish brown than the back ; tail-feathers dusky brown, 

 externally reddish brown ; crown of head like the back ; a white line 

 across the base of the forehead, widening into a large supraloral spot ;

At the time of writing the fourth volume of the ' Catalogue of 

 Birds,' I had not seen a specimen of Digenea submoniliger of Hume, 

 and I now propose to give a description of this species from the 

 series in the Hume Collection. 



Digenea submoniliger. 



Adult. General colour above light olive-brown, a little more ruddy 

 brown on the head ; wing-coverts like the back, the greater coverts
