BIEDS OF EGYPT. 319 



Heuglin in his work ; and this has rather shaken my con- 

 fidence in his remarks iipon the Calamodytce, as I think he must 

 have confounded it with some of the more nearly aUied species. 

 Calamoherpe arundiiiacea, the Reed- Warbler, probably escaped 

 my notice owing to its being a bird of passage ; although 

 during my tours I have spent about two months at difi'erent 

 times in February and March in the marshes of the Delta. 

 C. palustris is a bird which neither myself nor Von Heughn 

 ever met with ; but it is included as a bird of both Egypt and 

 Nubia upon the authority of Riippell and Lichtenstein ; the 

 determination is, however, in my opinion, open to question. 

 Acrocephalus pallidus of Von Heuglin (Orn. N. O. Afr. p. 294), 

 said by him to be a resident both in Egypt and Nubia, puzzles 

 me as to what species it should be referred. I do not know 

 of an Acrocephalus to which the name of pallidus could be 

 applied ; and he especially remarks that it is not the Hypolais 

 pallida of Gerbe. I have referred it, in a footnote (p. 100), 

 to Hypolais eltsica. 



Of the three species of true Acrocephalus, A. turdoides 

 appears to me of doubtful occurrence j A. arahicus. Von 

 Heuglin, I only know from his description (Orn. N. O. Afr. 

 p. 289) ; but it seems to me to be probably a good species 

 and to occur in Egypt. 



Hypolais olivetorum has been collected by Mr. Rogers 

 near Alexandria. I mention it here as it is new to the 

 country. H. elesica is a common Egyptian and Nubian 

 species ; it is included by Von Heuglin under a collective 

 specific name, H. languida, of which he recognizes five sub- 

 species, and includes his Acrocephalus pallidus, which a few 

 pages previously he referred to a different genus. Owing to 

 this apparent indecision of the author I have refrained from
