8 BRITISH BIRDS. 



both forms are practically indistinguishable, it was only on 

 October 6th, 1902, that an adult male with the characteristic 

 white spot was picked up close to Dungeness Lighthouse, 

 which it had struck, and was afterwards exhibited by Mr. 

 M. J. Nicoll (Bull. B.O.C., XII., p. 14). On September 1st, 

 1905, a similar adult male was obtained near Hastings, 

 and was exhibited by Mr. C. B. Ticehurst (BuU., XVI., 

 p. 34). 



The distribution of these two forms appears to be as set 

 down in my Manual, p. 36, and a statement that the Red- 

 spotted bird had bred in the mountains of Bohemia, above 

 the Elbe valley, has been denied on very liigh authority. 

 It is now admitted that the male with an entirely blue 

 breast represents a phase of the White-spotted Bluethroat. 



[Two examples of the Siberian Ruby-throat, Calliope 

 camtschatkensis, are said by Mr. Joseph P. Nunn, of 

 Royston, to have been well observed by him near 

 Westgate-on-Sea early in October, 1900 (c/. "Ibis," 1901, 

 p. 158). This is not enough to warrant the admission of 

 the species to the British List, but Mr. Nunn's reputation 

 for accuracy requires the courtesy of a record. Two 

 examples of this species have been obtained in the south- 

 east of France, and four or five in Italy during the last 

 twenty years, but as a rule the species is not found to the 

 west of the Ural and the Caucasus.] 



[A male of the Thrush-Nightingale or "Sprosser," 

 Daulias philomela, was obtained at Smeeth, Kent, on 

 22nd October, 1904, and exhibited by Mr. M. J. Nicoll 

 (Bull. B.O.C., XY., p. 20); but later [torn, cit, p. 47) 

 Dr. Hartert gave good reasons for suspecting this to be 

 one of the many annually exported by dealers. For the 

 present, therefore, it does not seem expedient to admit 

 this species to the British List.]
