Mr. Layard's ' Birds of South Africa.' 155 



1817. These two names are coequal; Svvainson, however, has 

 applied the name of savignyi to two different species, viz. : — 



M. savignyi, Swains. Zool. 111. pi. 7Q = M. albicollis, Vieill. 

 N. Diet. d'Hist. Nat. xiv. p. 15. 



M. savignyi, Swains. B. W. Afr. ii. p. 77, pi. v'\\. = M. chryso- 

 cercus, Cab. & Heine^ Mus. Hein. ii. p. 139. 



" This latter is closely allied to M. cegyptius " *. 



Hemipteryx immaculata, Hartl. Plain-breasted Pincpinc. 



Mr. Layard's ' Catalogue ' does not include this new species 

 discovered at Windvogelberg by Capt. Bulger, and described by 

 Dr. Hartlaub in the 'Proceedings ' of the Zoological Society of 

 London for 1866 (p. 22). 



147. Drym(eca pallida, A. Smith. See below, under no. 162. 



149. Drymceca natalensis, A. Smith. Natal Drymoeca. 



In both this species and the nearly allied D. curvirostris the 

 male is considerably larger than the female, a fact which has 

 been already noticed (Ibis, 1865, p. 274) ; but as it seems to 

 me an interesting peculiarity, I am desirous of again drawing 

 attention to it, as a point not to be lost sight of in the study 

 of this genus. 



153. Drym(eca aberrans, A. Smith. Aberrant Drymoeca. 



I regret to find that I have fallen into an error with re- 

 ference to a specimen which was sent to me from Natal, and 

 mentioned by me in 'The Ibis' (1863, p. 324) as belonging to 

 this species. It proves, on closer examination, to be an example 

 of D. affinis, Mr. Layard's no. 154. The only specimen I have 

 seen of the true D. aberrans is Sir A. Smith's original type, 

 which is preserved in the British Museum. 



162. Drymceca melanorhyncha, Jardine and Fraser, 

 Mr. G. R. Gray informs me that, from a recent examination of 

 specimens, he has arrived at the conclusion that D. melano- 

 rhyncha (Contr. Orn. 1852, p. 60) must be considered merely 

 a synonym of D. pallida, no. 147 of Mr. Layard's ' Catalogue,' 



* [It would therefore appear that Mr. Layard's No. 112 should stand 

 as M. chrysocercm ; but see Herr O. Finsch's remarks (J. f. O. 18G7, 

 pp. 239-245).— Ed.]
