 found in Great Bermuda. This specimen is probably the 

 egg of a bird and not of a cheloniau. (Courtesy of Dr. A.

Eggs of Turtles {Chelone), imbedded in coral-sand 

 which has consolidated through evaporation and the de- 

 position of lime from the sea-water, so that the eggs have 

 been prevented from hatching. In some cases the remains

Mr. P. F. BuNYARD, in reply to the Rev. F. C. R. 

 Jourduin's criticism regarding the breeding of the Grey- 

 headed Wagtail {M. Jlava borealis) in Kent, made the 

 following remarks : — 



In the 'Bulletin' for April 12th, 1922, Mr. Jourdain 

 endeavours to throw doubt on this record, which, he says, 

 "rests solely on the statement of Mr. G. Bristow." This 

 is not correct, as the birds were carefully examined by 

 Dr. Norman Ticehurst, and recorded in his ' History of 

 the Birds of Kent,' p. 97, where it is mentioned that 

 Mr. Bristow had had a considerable number of Blue-headed 

 and Grey-headed Wagtails through his hands, and was fully 

 qualified to identify them. 



It is now seventeen years since I exhibited the male 

 and female of the species in question, together with the 

 nest and eggs (Bulletin B. 0. C. vol. xix. 1906, p. 23). 

 Mr. Jourdain is surely a little late with his criticism, the 

 record having never previously been questioned. 



In a criticism of Mr. Bunyard's remarks, Mr. Witherby 

 pointed out that the real point at issue was not whether the 

 birds shot were referable to the subspecific form, Al. jiava 

 borealis, but whether the nests and eggs exhibited by 

 Mr. Bunyard in 1906 did, in fact, belong to them.
