For '' May lOtli" in the fourth entry under this head 

 read " May 18th." 



P. 146. Aedon lusclnia (L.). The egg from Parnassus, taken 

 by Seebohm and Kriiper is not that of this species, but 

 the Common Niglitingale, A. megarhyncha. The 

 Northern Nightingale does not breed in Greece. 



P. 167 and 17] . Sa.ricola stapazina (L.) and S. melanoleuca 

 (Gvikl.). These two supposed species are now known 

 to be merely dimorphisms, and should be united. This 

 also applies to the Western race {S. caterince and 

 S. occidentalis). 



P. 170. Saxicola luqens Licht. The eggs figured and de- 

 scribed under this title appear to be all erroneously 

 identified. All the eggs collected and carefully 

 identified by Koenig, Rothschild, Hartert, and myself 

 in Algeria are of quite a different type, having a 

 pale bluish or bluish-white ground, like the eggs of 

 iS. leucura. No reference is given to the excellent 

 figures of a genuine clutch in the Journ. f. Ornith. 

 1896, tab. vii. fig. 4, which differ widely from that 

 given on plate vii. fig. 6 of the ' Catalogue.-' 



P. 179. LocusteUa luscinoidcs (Savi). For "q Hungary, 6tli 

 June" read "5 (clutch) Velencze, Hungary, 16th May 

 (F. A. Cerva)." 



P. 180. Acrocephalus aquaticus (Temm.). For "Anl<lani, 

 5th June " read " Mark Brandenburg, 30th May." 



P. 185. A. streperus (Vieill.). Among the eggs collected 

 by Tristram and Salvin in Algeria were some wliich 

 were ascribed by them to A. aquaticus. The writer of 

 the ' Catalogue ' in my opinion quite rightly recorded 

 them under the title of A. streperus, to which the three 

 eggs from Zana undoubtedly belong and probably the 

 others also. The original finders' identification should, 

 however, have been recorded in brackets. On examining 

 these eggs in July 1913 I find they have been trans- 

 ferred to A. aquaticus. 



P. 212. Sylvia orpheus Temm. In the description of the eggs 

 of this species the writer has overlooked the fact that
