norus they are pure white. The wing in M. polyzonus measures 12 
inches, in M. canorus, 15 inches. 
16. W. Polyboroides radiatus (Scop.). (Faleo gymnogenys, Temm.) 
17. N. Circus pallidus, Sykes. 
18. W. Scops leucotis (Temm.). 
19. W. Seotornis elimacurus (Vieill.). 
20. Caprimulgus infuscatus, Cretzschm., female. Agrees with 
Riippell’s plate, but wants the white wing- and tail-spots of the male 
bird. 
21. W. Eurystomus afer (Lath.). (£. orientalis, Riipp.; E. ru- 
bescens, Vieill.; Collaris purpurascens, Wag}.) 
22. W. Coracias abyssinica, Gm. (Coracias caudata, Wagl.) 
23. W. Coracias nevia, Daud. (C. levaillanti, Riipp.; C. nu- 
chalis, Swains.) 
24. W. Ceryle rudis (Linn.). (Ispida bicincta, Swains.; I. bitor- 
quata, Swains.) Identical with specimens from Smyrna and S. Eu- 
rope. The individuals with two pectoral bands (I. bicineta, Swains.) 
are the males. 
25. N. W. Merops albicollis, Vieill. (M. cuvieri, Licht.; M. sa- 
vigny?, Swains.) 
26. W. Merops nubicus,Gm. (M. superbus, Shaw; M. ceruleo- 
cephalus, Lath.) 
27. W. Merops lamarcki, Cuv. (M. viridissimus, Sw.; M. egyp- 
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, Guérin.) 
29. Irrisor senegalensis (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 (I. 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 I. erythrorhynchus the 
white bar of the primaries is much narrower, and divided by the black 
shaft. 
30. Nectarinia metallica, Ehrenb. 
31. W. Nectarinia pulehella (Linn.). 
32. Phylloscopus trochilus (Linn.). Identical with British spe- 
cimens. 
33. Sazicola deserti, Temm. 
34. Saxicola enanthe (Linn.). 
35. Savicola isabellina, Cretaschm. This is probably the Sylvia
