SPECIES NOT SEEN BY THE AUTHOR. 223 
C(ssia; but it has a larger bill and feet, and lacks the 
white on the tail-feathers of that bird. The legs and feet also 
differ in being of a leaden grey colour. 
6. Melizophilus sardus, Marm. Marmora's Warbler. 
This bird is mentioned as having been only once seen, near 
Palma, in the island of Majorca. 
It has been described as much resembling the Dartford 
Warbler {Melizophilus provincialis) in its habits, but frequent- 
ing lower ground {cf. Mr. A. B. Brooke, in ' The Ibis/ 1873, 
p. 242) . That gentleman further says it is very abundant in 
Sardinia. 
This species resembles the Dartford Warbler in size and 
shape, but has none of the rufous of that bird. 
7. Hypolais olivetorum, Strickland. The Olive-tree 
Warbler. 
This Warbler is mentioned by Mr. Saunders as seen in a 
museum at Valencia; but according to Mr. Dresser, in his 
' Birds of Europe,' it has not been recorded from any other 
locality westward of its chief habitat (Greece), though it is 
stated to have occurred in Algeria and also in Tangier and 
Fez (Naumannia, ii. part i. p. 77) . 
The song is said to be so marked as to render it unlikely 
to remain unnoticed by a field-naturalist ; and, like the rest 
of the genus, it is a tree-frequenting bird, chiefly affecting 
olive-groves. 
The general colour of the upper parts is a dull brownish 
grey, the underparts being white; and it has a white 
eyebrow. 
Total length 6 inches. 
8. AcROCEPHALUs MELANOPOGON, Tcmm. The Moustached 
Sedge- Warbler. 
This species is common near Valencia, and to be looked 
for in sedge-covered swamps and reed-beds.
