There were five birds in the flock, but the fifth had appa- 

 rently escaped. The birds exhibited had been examined 

 in the flesh by Mr. R. Butterfield, Mr. L. C. Edwards, 

 and others, and had been mounted by Mr, Bristow, of 

 St. Leonards. They had been presented to the Booth 

 Museum by Messrs. J. E. Hall and E. Robinson. 



Mr. Griffith also exhibited an adult male example of the 

 Grey-backed Warbler {Aedon familiaris , Menetr.) which had 

 been shot at Ninfield, Sussex, on the 13th of May, 1910, by 

 Mr. Morris, and examined in the flesh by Mr. L. C. Edwards. 

 It had been mounted by Mr. Bristow, of St. Leonards, and 

 purchased by the exhibitor, who had presented it to the 

 Booth Museum at Brighton. 



[This appears to be the second British-killed example of 

 this species, tbe first having been obtained at Hythe, Kent, 

 on the 15th of July, 1907 : cf. Nichols, Bull. B. O. C. xxl 

 p. 63 ; id. in Witherby's Brit. Birds, i. p. 257 (1908).— Ed.] 



Mr. Griffith also made the following remarks : — 

 " On getting out of the train at Orpington Station, Kent, 

 about 4.20 this afternoon (14th November, 1910), I saw a 

 continuous steady flight of Rooks passing south towards 

 Earnborough. They continued in an unbroken stream for 

 15^ minutes, from ten to over twenty abreast, at an average 

 distance apart of about 15 feet along the line of flight. The 

 rate of flight appeared to be rather over 10 miles an hour. 

 These figures show that the total number which passed over 

 me was about 13,600. How many had passed before my 

 arrival, I cannot, of course, guess ; but they then stretched 

 southwards as far as the eye could see.^' 



Mr. C. Chubb, on behalf of Mr. F. V. McConnell, 

 exhibited an example of Micrastur guerilla, Cass., which had 

 been obtained at Ituribisce, British Guiana. Hitherto the 

 species had been known to range only from Southern Mexico 

 to Panama and Ecuador.
