Hypolais polyglotta. 
Common near the river. On May 27tli many nests were 
taken with from three to five eggs_, nearly all fresh ; they 
Avere mostly in low bushes^ well concealed_, and made of 
grass_, lined with hair or fine grass, 
Hypolais opaca. 
More abundant than the former species ; several nests were 
found in tamarisk-bushes near the river. These nests, often 
much exposed, were deep, cup-shaped, and made of grass, 
well lined with cotton-down, thistle-down, and in one case 
with sheep's wool; the lowest was about 4 feet from the 
ground, the highest about 12 feet. No nest contained more 
than four eggs, and some of these were slightly incubated on 
May 28th. 
ACROCEPHALUS TURDOIDES. 
Very numerous on the river-banks wherever reeds were 
found ; their harsh song might be heard all through the 
day and most of the night. On May 7th they were just 
beginning to lay, and we found nests with from one to three 
eggs ; on May 24th we saw others containing from four to 
six eggs, mostly incubated. The nests are counterparts of 
those of our Reed-Warbler, though of course on a larger 
scale; very substantial, deep, and easily found. 
AcROCEPHALUS STREPERUS. 
Not very common. Nests found from May 7th to 
May 28th. 
Cettia cettii. 
The first nests found, on May 6th, contained four eggs 
each, one clutch too much incubated for preservation ; others 
with four and five eggs on May 11th and after. They were 
all in tamarisk-bushes near the river, compactly put together, 
deep, made of grass, and lined with horsehair. Unlike 
those mentioned by Col. Irby, these nests were placed almost 
in the open and were quite easily seen. The bird seems to be 
very local, but numerous where it is found.
