25. N. W. Merops albicollis, Vieill. (M. cuvieri, Licht.; M. sa- 

 vignyi, Swains.) 



26. W. Merops nubicus, Gm. (M. superbus, Shaw ; M.cceruleo- 

 cephalus, Lath.) 



27. W. Merops lamarcki, Cuv. (iW. viridissimus, Sw.; iW. cegyp- 

 tius, Kittlitz ; M. viridis, Riipp.) Closely allied to M. viridis, Linn., 

 of India, but smaller, with a larger mixture of golden yellow in the 

 plumage, the throat not blue as in M. viridis, and the remiges are 

 rufous on both webs, with scarcely any tinge of green externally. 



28. W. Merops erythropterus, Gm. (M. minulus, Cuv.; M. col- 

 laris, Vieill.; M. lafresnayei, Guerin.) 



29. Irrisor senegulensis (Vieill.)? The Kordofan specimens agree, 

 in the shortness and nearly straight form of their beak, with the 

 black-beaked species of W. Africa, I. senegalensis, Vieill. {Nectarinia 

 melanorhynchus, Licht.), but in the red colour of this organ they 

 agree with the Cape species (/. erythrorhynchus). It is well known 

 that the females of the latter have the beak much shorter and straighter 

 than the males, yet in these Kordofan specimens the beak, though of 

 the same length, is considerably straighter than in the female birds 

 from the Cape. Like I. senegalensis they have a broad white bar 

 crossing the inner webs of the first three, and both webs, shaft in- 

 cluded, of the remaining primaries ; while in J. erythrorhynchus the 

 white bar of the primaries is much narrower, and divided by the black 

 shaft. 



30. Nectarinia metallica, Ehrenb. 



31. W. Nectarinia pulchella (Linn.). 



32. Phylloscopus trochilus (Linn.). Identical with British spe- 

 cimens. 



33. Saxicola deserti, Temm. 



34. Saxicola cenanthe (Linn.). 



35. Saxicola isabellina, Cretzschm. This is probably the Sylvia 

 leucorrhoa, Gm., in which case it extends to'Senegal. It resembles 

 S. cenanthe, but is paler on the upper part, and has less white on the 

 lateral rectrices, the terminal black portion being 1^ inch in length, 

 while in S. cenanthe it is only about % inch. 



36. Motacilla capensis, Linn. 



37. Budytes melanocephala (Licht.). 



38. Anthus (undetermined species). 



39. W. MeleenornisX erythropterus (Gm.). (Turdus erythropte- 

 rus, Gm.) This bird approaches nearly to the type of Melcenornis, 

 Gray (Melasoma, Sw.), though the beak is rather more elongated, 

 and the rictal bristles less developed, than in M. edoliolides, Sw. 

 Ruppell refers it to Boie's genus Cercotrichas, which is synonymous 

 with Copsychus, "Wagl. Dr. Hartlaub places it in Argya, Lesson, 

 which is synonymous with Chcetops, Sw. 



40. W. Pycnonotus barbatus (Desfontaines) . (Turdus barbatus, 

 Desfont. in Mem. Ac. Sc. 1787; Turdus arsinoe, Licht.; Ixos ob- 

 scurus, Temm. ; i". inornatus, Fraser ; Hcematornis lugubris, Less.) 



41. Oriolus galbula, Linn. 



42. W. Dicrurus divaricatus, Licht. (D. lugubris, Ehrenb. ;
