XXXVI. — On some rare or un figured Eggs of Palcearctic 

 Birds. By H. E. Dresser, F.Z.S., M.B.O.U., &c. 



(Plate X.) 



In continuation of former papers on the subject *, I now 

 beg leave to offer to the readers of ' The Ibis ' some further 

 notes on rare or unfigured eggs of the birds of the Eastern 

 Palsearctic area, with illustrations. 



(1) Lusciniola aedon. Thick-billed Warbler. (PL X. 

 figs. 1, 2.) 



Lusciniola aedon Dresser, Man. Pal. B. p. 124. 



This Warbler is not uncommon in Dauria, where Messrs. 

 Dybowski and Godlewski found it nesting almost every- 

 where. An egg obtained by these gentlemen was figured as 

 long ago as 1873 (J. f. 0. 1873, Taf. i. fig. 1) by Taczanowski. 



* See < Ibis ' 1901, p. 445 ; 1902, p. 177 ; 1903, pp. 88, 404 ; and 1904, 

 pp. 106, 280. In the last paper I regret to find that an error has 

 occurred in the " Explanation of the Plate" (p. 283). Figures 1 and 3 

 represent the eggs of Pycnonotus leucotis, and figures 4 and 5 those of 

 Chimarrhornis leucoeephalus.
