leucorrhoa, Gm., in which case it extends to Senegal. It resembles 
S. enanthe, but is paler on the upper part, and has less white on the 
lateral rectrices, the terminal black portion being 1,1; inch in length, 
while in S. enanthe it is only about 4 inch. 
36. Motacilla capensis, Linn. 
37. Budytes melanocephala (Licht.). 
38. Anthus (undetermined species). 
39. W. Melenornis? erythropterus (Gm.). (Turdus erythropte- 
rus, Gm.) This bird approaches nearly to the type of Melenornis, 
Gray (Melasoma, Sw.), though the beak is rather more elongated, 
and the rictal bristles less developed, than in M. edoliolides, Sw. 
Riippell refers it to Boie’s genus Cercotrichas, which is synonymous 
with Copsychus, Wagl. Dr. Hartlaub places it in Argya, Lesson, 
which is synonymous with Chetops, Sw. 
40. W. Pyenonotus barbatus (Desfontaines). (Turdus barbatus, 
Desfont. in Mém. Ac. Sc. 1787; Turdus arsinoe, Licht.; Ixos ob- 
scurus, Temm.; I. inornatus, Fraser ; Hematornis lugubris, Less.) 
41. Oriolus galbula, Linn. 
42. W. Dicrurus divaricatus, Licht. (D. lugubris, Ehrenb. ; 
D. canipennis, Swains.) Nearly allied to the D. musicus, Vieill., of 
S. Africa, but has the tail less deeply forked, the culmen of the beak 
more acute, and the primaries pale internally. 
43. Lanius algeriensis, Less. in Rev. Zool. 1839. This is probably 
the species termed L. ewcubitor by Rippell. It differs from the true 
excubitor of N. Europe in the greater extent of white on the prima- 
ries, and in the two external pairs of rectrices being wholly white (ex- 
cept the shafts). It closely approaches L. lahtora of India, and only 
differs in wanting the narrow band of black across the front. 
44, Lanius nubicus, Licht. (L. personatus, Temm.) 
45. Lanius collurio, Lim. A young male specimen appears refer- 
able to this species. 
46. N. Lanius isabellinus, Ehrenberg, Symb. Phys. fol. e. This 
species is pale fulyo-cinereous above, cream-coloured below; rump and 
tail rufous ; a broad blackish band from the nostril to the ear-covers, 
margined above by a whitish streak. It much resembles L. arena- 
rius, Blyth, Journ. As. Soc: Beng. vol. xv. p. 304, but is of a more 
cinereous tinge above, and is distinguished from that and all the allied 
Asiatic species by possessing a conspicuous white band at the base of 
the fourth to the ninth primaries. ‘The specimen from Kordofan has 
an obscure dark transverse band near the tips of the rectrices. 
47. W. Telophonus senegalus (Limn.). (Lanius erythropterus, 
Shaw.) 
48. W. Corvus seapulatus, Daud. (C. leuconotus, Sw.) 
49. Corvus umbrinus, Sundevall. Distinguished by the length and 
curvature of the beak, and by the grey-brown tint of the head and neck. 
50. W. Juida rufiventris, Ripp. 
51. W. Juida chalybea, Ehrenb. (Lamprotornis cyanotis, Sw.) 
52. W. Ploceus luteolus, Licht. (P. personatus, Vieill., Jard. 
Contrib. to Ornith. 1849, p. 35. pl. 7-)
