RIVER GABOON IN WEST AFRICA. 
Rump-feathers very long and thick. This bird will be figured in the 
Illustrations to the Proceedings of the Zoological Society. 
*8. Pratincola olax, Verreaux MS. Resembles P. rubdicola, of 
Europe, and still more P. pastor, Strickland, of S. Africa, but the 
beak is wider, and the breast only is rufous, the sides being white. 
*9. Lamprocolins purpureiceps, Verreaux. Whole head and throat 
glossy violet purple; whole back, breast and belly, glossy bluish- 
green; wings glossed with steel blue; the primaries externally with 
violet ; tail black, slightly glossed with purple; beak and legs black. 
Total length, 7.2; beak to front, 6; to gape, 8; wing, 4.3; 
medial rectrices, 2.8; external, 2.9; tarsus, 7. 
10. Nigrita canicapilla, Strickland. This bird, hitherto found 
only in Fernando Po, is now shown to extend to the adjacent Afri- 
can continent. 
*11. Migrita lutifrons, Verreaux MS. A typical species of this 
very limited genus, resembling N. canicapilla in the general arrange- 
ment of colour, but smaller, and wants the black front and the 
white wing spots. It will be figured in the Illustrations of the 
Proceedings of the Zoological Society. 
12. Malimbus rubricollis (Swainson). (Huplectes rufovelatus, 
Fraser), 
"13, Anthreptes aurantius, Verreaux MS., closely allied by the 
Stout straight form of beak to A, longuemaret of Senegal, though 
the arrangement of the colour, and especially the orange tufts on the 
sides of the breast, connect it with Nectarinia. It will be figured in 
the Illustrations of the Proceedings of the Zoological Society. 
14. Nectarinia chloropygia, Tard. 
15. Nectarinéa stangert, Jard. 
16. Nectarinia fuliginosa, Shaw)’ Differs from N. Suliginosa 
as usually described, in having the upper tail-coyers purple instead 
of brown like the rest of the upper parts. In this state it is 
described by Lesson in his “ Description de Mammiféres et d’ Oiseaux 
récemment découverts,” p- 271; but whether it be a peculiar state 
of plumage, or a distinct species, we have as yet no eyidence. 
17. Nectarinia superba (Vieill.)? This splendid bird is labelled 
by Verreaux, « Tinnyris sanguineus, Less. C. superbus, Vieill.” 
It agrees with the descriptions of N. superba (Vieill.), except in 
Wanting the golden green band which separates the violet purple 
of the throat from the dull red of the breast. The vent and lower
