when we consider the difficulty of obtaining the exact names 

 and addresses o£ the zook:)gists scattered over the whole of 

 the civilized world, and of ascertaining the composition of

XXXVIII. — Letters, Extracts, Notices, ^'c. 



We have received the following letters, addressed to "The 

 Editors":— 



Sirs, — I have the great pleasure to record the finding of 

 two nests and eggs of the Honey-Buzzard {Pernis apivorus) in 

 Somersetshire in May 1897 and May 1899 by Mr. Charles 

 E. Nipper, of Axbridge, Somerset. The first nest was dis- 

 covered at an isolated spot called Callow Rocks, and con- 

 tained four eggs. The second nest was found on the highest 

 ])oint of the Mendips, Blackdown, and this also contained 

 four eggs. 



Both nests were rudely constructed, the first being half- 

 way down a precipitous clitf and the second amongst some 

 boulders on the ground. 



In each case the female bird was seen and recognised as 

 the Honey-Buzzard. 



Yours &c., 



St. Albans, Heit3, W. Percival Westell, M.B.O.U.

 p. 2.27, there is a remark about Waikthlatingmayalwa in 

 the Great Chaco being the most southern locality where 

 Formicivora strigiluta has been found. This statement is 

 not quite correct, as the species had already been noticed 

 from San Lorenzo, in the Argentine province of Jujuv, 

 where it was obtained by Dr. Borelli [Boll. Mus. Tor. N. 392 

 (1897), p. 22 ; N. 378 (1900), p. 9]. In the latter reference
