Gl. ACROrEPIIALUS ARUNDINACEUS (L.)- G icut Kecil- 

 Warbler. 



Occurs on passage in small numbers. Wharton saw five 

 and sliot three on the east coast, Aj)ril 16-22 ; Avhile White- 

 head only met Avith it on passage i'rom May 7 to 8. 



62. AcKOCEPHALUs sTREPERUs (Vicill.). Rccd-Warblcr. 

 Giglioli describes tliis species as scarce along the east coast, 



and erroneously quotes Wharton in support o£ this state- 

 ment, but it does not appear in Wharton's list. Backhouse 

 shot at a bird in some reeds in the Gulf of Ajaccio which 

 may have belonged here. Confirmation of this record is 

 desirable. 



63. AcRocEPHALus scH(EN0B-f:NU3 (L.). Scdge-Warblcr. 

 Occurs on migration in spring and autumn. Wharton 



found it fairly common at Bignglia during April, and 

 Giglioli records it as seen on October 5 near Sagoue and on 

 October 11 at Ostriconi. 



64. AcRoCEPHALUs AQUATicus Gm. Aquatic Warbler. 

 Wharton saw several at Biguglia at the end of April, but 



found it mnch less common than the Sedge-Waibler. The 

 dearth of AcrocepJiali in the reed-beds on the east coast is 

 ]-eii!arkable, in view of the ample supply of insect food. 



67). Hypolais polyglotta (Vieill.). ]\Ielodious Warbler. 

 Giglioli shot one near Porto Vecchio on September 26. 



66. Sylvia ATRiCAPiLLA (L.). Blackcap. 



Sijlcifi airicapilla pauluccii Arrigoni, Avicula, vi. p. 103 

 (1902— Sardinia). 



Local names : Terraiolo, Capinera (Giglioli). During 

 the winter Blackcaps are common, esiiecially near Ajaccio, 

 but in the summer they seem to be much less plentiful, 

 though a certain number are to be found. Parrot believed 

 that the majority of the winter visitors were not northern 

 birds, but indigenous to the island, belonging to a darker race 

 with darker grey nape and sides of the neck and less olive on 

 the back. Whitehead found a nest, with young a few days 

 old, on ]\Iay 29, and I obtaiiied one with four fresli eggs on
