186 ZOSTEROPS GRISEOVIRESCENS. 



white ; lores and sides of forehead yellowish white, of the same colour as 

 the entire under parts ; under wing-coverts and inner margins of quills 

 white. Bill brown with the under mandible pale; iris brownish yellow; 

 tarsi and feet brown. Total length 4-5 inches, culmen 04, wing 2, tail 1"5. 

 Prince's Is. (Dohrn). 



The Prince's Island White-eye is probably confined to the 

 island of that name, which is separated from the Gaboon coast 

 by about 180 miles of Atlantic Ocean. 



Here Dr. Dohrn found the species frequenting the hilly 

 parts of the interior, and remarks that it much resembles our 

 Willow Warbler (Phylloscopus trochilus), not only in its colour- 

 ing but also in its song. 



Signor Sousa informs us that the Lisbon Museum con- 

 tains a specimen labelled " St. Thomas Island, 1880." A 

 collector of St. Thomas Island birds would probably visit 

 Prince's Island, and most likely obtained the bird at the latter 

 place, for there is no other record of the species being found 

 elsewhere than on Prince's Island. Or can the bird be really 

 a specimen of the nearly allied, but larger, form Z. griseo- 

 virescens from Annobon Island ?

Type. According to the original description it is compared to Z. ficedu- 

 Una, but is a larger bird, with a longer and stronger bill. Upper parts grey

 yellow shade on the upper tail-coverts ; under parts white tinted with

 sulphur yellow ; least and median wing-coverts like the back ; greater

 margins and narrow greenish yellow outer edges ; bend of wing and under 

 wing-coverts pure white ; tail feathers brown narrowly edged with green.
