THE ZOOLOGIST. 



previously found in the Eeed- Warbler's nest. I was very surprised 

 and pleased to again find the Marsh -Warbler breeding, and especially 

 so at finding a Cuckoo's egg in the nest, for there are very few 

 instances of its occurrence in England. The nest was placed some 

 twelve yards back from the river on firm though damp ground ; it 

 was not more than eighteen inches from the ground, and was com- 

 posed entirely of dry round bents, fairly substantially made, and 

 having two live nettle-stems woven into the sides. The actual spot 

 was in the parish of Wraysbury, in the county of Bucks (Wyrardis- 

 bury, as it used to be called), and is not more than five miles from the 

 Surrey plantation where I met the birds in 1907. I informed my 

 friend Mr. Edward Pettitt, of Wraysbury, of my find, and, as he is in- 

 terested in ornithology, asked him to let me have any further news of 

 the birds. On June 30th he succeeded in finding another nest in the 

 same nettle-bed, and within a yard or two of my previous nest ; this 

 nest contained four Marsh-Warbler's eggs and one Cuckoo's, the 

 latter being of a third type — that is to say, quite distinct from 

 either the egg I found in my Marsh-Warbler's nest or in the Reed- 

 Warbler's. This second nest was again built of dry bents and 

 placed about eighteen inches from the ground, and had two pieces 

 of dead loosestrife and two live nettles woven into the sides. It 

 may be that the Marsh-Warbler is attempting to establish itself 

 along this part of the Thames, but more evidence is required 

 before one can form an opinion on this point. I may say, how- 

 ever, that previous to 1907 I had never met the bird in these 

 parts, though I had worked along the river for many years, and 

 always hoped to meet it one day. — Graham W. Kerr (Ditton Lodge,

Raven in Surrey. — On the 12th September last I both heard and 

 saw a Raven (Corvus cor ax) flying overhead here. The peculiar 

 croaking sound was unmistakable. I believe this bird has not been 

 previously, or at all events for many years, recorded in Surrey. —

Cormorant in Warwickshire. — Replying to Mr. Smalley's sugges- 

 tion (ante, p. 350), the bird I recorded (ante, p. 315) was of course, as 

 I stated, a Cormorant and not a Shag. The Common Cormorant 

 varies considerably in size, but the usual length seems to be about 

 36 in. ; wing from 12*5 in. to 11-00 in. The bird I referred to was a 

 small, young example, and thin. Its wing,was 13 in. — O. V. Aplin
