consider the specimen figured in Babington's " Birds of 

 Suffolk " a true C. adamsi (J. H. Gurney, ZooL, 1902, p. 99 : 

 cf. also W. R. Ogilvie-Grant, antea, Vol. I., p. 295).]

S. page 713. 

 North Wales. — One seen by Mr. T. A. Coward in Aberffraw 

 Bay, Anglesey, on April 21st, 1905, was in summer plumage 

 (H. E. Forrest, Vert. F. N. Wales, p. 406).

 S. page 715. 



Moult. — At the end of September and beginning of October, 

 1898, Mr. W. Farren had several examples of this species 

 sent to him, and the majority of the adults were entirely 

 devoid of flight feathers, both primaries and secondaries 

 being shed en masse [Aim. S.N.H., 1899, p. 114).

Scotland. — Tiree. — Two pairs in breeding plumage on a 

 loch on May 22nd, 1900, were reported {Ann. S.N.H., 1901, 

 p. 145). " Is now (1904) a rapidly extending species in the 

 nesting season, and nests freely in many parts both south and 

 north of Forth and Clyde. One was seen on May 7th, 1903, 

 in Assynt by Mr. F. L. Blathwayt, the first record for 

 Sutherlandshire " (J. A. Harvie-Brown, A Fauna of N.W. 

 Highlands and Skye, pp. 345-346). Three pairs nesting on 

 Lake of Menteith (Perth), in 1905. Breeding range still 

 slowly but surely extending (T. T. Mackeith. Zool., 1905, 

 p. 314). 



From the published records there seems to be no doubt 

 that in England the nesting birds are still increasing in 

 numbers. This increase is very noticeable in the Midlands. 

 Records of breeding from the northern counties (Cumberland, 

 Durham, Northumberland, etc.) seem to be lacking, however.
