handled tlie bird himself aad to have faithfully recorded 

 what he was told. I have therefore assigned this species to 

 Appendix A. 



Dr. Antonia Binna^s collection has unfortunately been 

 quite lost sight of, and nothing seems to be known of the 

 owner of this private collection or what has become of 

 the birds which it contained. 



Range. The West African Grey-headed Bush- Shrike is 

 found in the West African subregion from Senegal to 

 north Angola, ranging east to the Niara Niam country 

 and Tanganyika.

 Type locality : Provence. 



Floericke (Aus der Heimat des Kanarienvogels, 1905, 

 p. 51) says there is a specimen of this Warbler [Sylvia 

 provincialis) in the Museum at Laguna, Tenerife, which 

 was killed in a neighbouring town during the spring 

 migration. Cabrera, whose collection is housed in the 

 Laguna Institute, does not mention this bird in his Cata- 

 logo (1893), and Polatzek, who includes the species in his 

 list on the authority of Floericke, remarks (Orn. Jahrb. 

 1909, p. 124) that the bird must have been obtained since 

 Cabrera's Catalogue was published. 



I have not had an opportunity of examining this skin. 

 It may or may not be correctly identified, Floericke's 

 assertions require to be very carefully sifted. In any case 

 there is the possibility of its being a "trade-skin" which 

 has crept in amongst the Cabrera collection of locally-shot 

 birds. Unfortunately many of the birds in the Canary 

 Museums are undoubtedly killed anywhere but in the 

 Canary Islands. 



Range. The typical form of the Dartford Warbler in- 

 habits south-west Europe. Races have been described from 

 Great Britain (il/. u. dartfordiensis) and north-west Africa 

 (.1/. u. toni).
