Mr. Boyd Alexander exhibited and described examples 

 of the following new African species : — 



Neocossyphus granti, sp. n. 



? . iV". prcepectorali similis, sed paulo minor et rectricum 

 apicibus albis valde minoribus, speculo alari castaneo 

 distinguendus. Culmen 15 mm., ala 100, cauda 95. 



Hab. Beritio, R. Welle, 14. ii. 06. 



Obs. This specimen is similar to a female obtained by 

 Mr. D. Carruthers to the north-west of Lake Tanganyika. 



Mr. Ogilvie-Grant has already pointed out {' Ibis/ 1908, 

 p. 300) that the latter bird differed somewhat from a typical 

 female of N. prapectoralU, Jackson, from the Mpanga Forest, 

 Fort Portal, and might represent a distinct and rather 

 smaller form. The discovery of a second similar specimen 

 on the Welle River seems to confirm this opinion. 



Barbatula poensis, sp. n. 

 (J . B. leucolcema similis, sed major, et remigibus extus 

 viridescenti - flavo, nee olivascenti - flavo marginatis ; 

 gutturis et praepectoris albedine cinerascente usque ad 

 pectus extensa. Culmen 13 mm., ala 62, cauda 38. 



Hab. Moka, Fernando Po, 9. xii. 02. 



HyPOCHERA NIGERIA, sp. n. 



(J. H. cenece similis, sed Txbique viridi-nitens, miuime 

 chalybea. Culmen 8 mm., ala 65, cauda 45. 



IJab. Kiri, R. Gongola, 22. vii. 04. 



With regard to the genus Hypochera, I have come to the 

 conclusion that the light and dark brown of the quills 

 in the species is not a constant character. The light colour 

 seems to be due to the faded condition of the plumage, and 

 the males apparently assume the brown plumage of the 

 female in the non-breeding season. 



Sylvia olivi^, sp. n. 

 cj . S. galactodi similis, sed minor ; gutture, abdomine et 

 hypochondriis clare albidis, pectore minime coucolori- 

 bus. Culmen 14 mm., ala 75, cauda 73. 

 ? . Culmen 15 mm., ala 77, cauda 78. 

 Hab. Vicinity of Lake Chad, 21.xi.04.
