61. Acrocephalus arundinaceus (L.). Great Reed- 
Warbler. 
Occurs on passage in small numbers. Wharton saw five 
and shot three on the east coast, April 16-22 ; while White- 
head only met with it on passage from May 7 to 8. 
62. Acrocephalus streperus (Vieilh). Reed-Warbler. 
Giglioli describes this species as scarce along the east coast, 
and erroneously quotes Wharton in support of 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 schcenob,enu3 (L.). Sedge-Warbler. 
Occurs on migration in spring and autumn. Wharton 
found it fairly common at Biguglia during April, and 
Giglioli records it as seen on October 5 near Sagone 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 much less common than the Sedge-Warbler. The 
dearth of Acrocephali in the reed-beds on the east coast is 
remarkable, in view of the ample supply of insect food. 
65. Hypolais polyglotta (Vieill.). Melodious Warbler. 
Giglioli shot one near Porto Vecchio on September 26. 
66. Sylvia atricapilla (L.). Blackcap. 
Sylvia atricapilla pauluccii Arrigoni, Avicula, vi. p. 103 
(1902—Sardinia). 
Local names: Terraiolo, Capinera (Giglioli). During 
the winter Blackcaps are common, especially 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 May 29, and I obtained one with four fresh eggs on
