9A SYLVIIDiE. 
deep and cup-shaped^ largest at the base, measuring about 
4^ inches in height, the inside depth being 2j, the internal 
diameter 2| inches. The beautiful pink eggs, laid about the 
end of April, are usually five in number ; but I have known 
only three. They lose much of their beauty when blown. 
The birds are rather irregular as to the time of nesting, as 
I have seen nests nearly on the point of hatching and others 
with fresh eggs on the same day (13th of May). 
The males are about a quarter of an inch longer than the 
females; but the plumage of the sexes is the same. Sometimes 
the tail is marked, like Savi's Warbler, with indistinct bands 
of dark brown. The inside of the mouth is yellowish. The 
number of tail-feathers is ten only. 
104. AcROCEPHALUs scHCENOBiENus (Liuu.). The Sedge- 
Warbler. 
Favier says this is a very rare species near Tangier, that he 
seldom saw more than one or two on passage, in March or in 
September. I never obtained it on the Spanish side. 
This species has a broad yellow-white eyebrow, the top of 
the head being brown streaked with blackish brown. 
Length about 4|-5 inches. 
105. AcROCEPHALus AQUATicus (Lath.). The Aquatic 
Warbler. 
This species is mentioned by Mr. Drake as having been 
met with in Morocco. It is found in Andalucia, though I 
only saw it once myself. 
The top of the head, which is brown, has a bufl&sh white 
band down the centre and a buflf-coloured eyebrow, and is a 
rather smaller bird than the Sedge- Warbler. 
106. AcROCEPHALUs N^vius (Pcnu.). ^ The Grasshopper- 
Warbler. •^'* 
Is recorded from Morocco and also from Andalucia in 
winter ; but I did not myself observe it. 
Length about 5| inches.
