quite different from any note of the Chiffchaff. which I have 

 heard, though I have observed numbers of these birds 

 wintering in the south of France. It has a single note, a 

 good deal like that of a Coal-Titmouse or Hedge-Sparrow, and 

 certainly not like the note described by Seebohm and Gatke. 



" An example of some allied species of Phylloscopus, which 

 I saw in West Kent three or four years ago, in December 

 and January, was much greener and yellower. 



"It may or may not be a mere coincidence that the bird 

 has taken up its quarters in a locality where I have twice 

 before, and again this year, seen Firecrests [Regains igni- 

 capillus) in winter/' 



Mr. W. Fitzherbert Brockholes exhibited eggs of the 

 following species of birds, showing remarkable variations 

 both in shape and colour : — 



1. Mistle-Thrush. Two clutches showing variation in 

 size. 



2. Blackbird. Two clutches showing variation in shape. 



3. Blackbird and Hedge-Sparrow. The eggs of both 

 species, laid in a nest jointly constructed by these birds, have 

 already been described in the ' Bulletin ' (cf. x. p. ciii, 1900). 



4. Song-Thrush. A remarkable clutch of seven very 

 small eggs, much like those of a Hedge-Sparrow, taken at 

 Claughton, Lancashire, on the 9th of May, 1908. The 

 following year a similar clutch of six was found near the 

 same place. 



5. Skylark. Clutch of four almost white eggs taken at 

 Overton, Lancashire, on the 30th of April, 1913. A similar 

 clutch of four eggs had been found on the same field a 

 fortnight later. 



6. Nightingale. A clutch of very light-coloured eggs. 



7. Robin. A clutch of white eggs, one being beau- 

 shaped. 



8. Sedge-Warbler. A clutch of white eggs. 



9. Blackcap. Two clutches of the rufous type. 



10. Garden-Warbler. A clutch of the rufous type, 

 believed to have been laid by this species.
