1920.| the Birds of the Anglo-Eyyptian Sudan. 803 migrant. Unfortunately all our specimens happen to be winter birds, and Mr. Butler looked on it also as only a winter migrant. We lave, therefore, no summer birds from within our limits to compare with those from elsewhere. As to coloration we can see very little difference indeed between N.W. African, N.E. African, and European birds, though some of the N.W. African examples are certainly darker and somewhat approach G. p. fiilleborni of southeastern Africa, which is undoubtedly a resident race.

Glareola nordmanni.

Glareola nordmanni Fischer, Bull. Soc. Imp. Nat. Moscou, xv. 1842, p. 314: S. Russia.

Glareola melanoptera auct., Reichw. V. A. 1. p. 145.

[B. coll.] 1 Mongalla Oct. Mon. A winter migrant to tropical and South Africa.

Glareola (Galachrysia) nuchalis nuchalis.

Glareola nuchalis Gray, P. Z. 8. 1849, p. 68, pl. 9: Sth Cataract of the Nile.

This bird, only known from the type, was secured by Galton at the 5th Cataract near Berber, and the British Museum Catalogue of Birds is therefore wrong in giving the Upper White Nile as its habitat. From an examination of the material in the Museum, it appears that the white and red-necked forms of this bird intergrade, and they are therefore best considered as one species.

Glareola (Galachrysia) nuchalis emini.

Glareola emini Shelley, P. Z. S. 1888, p. 49: Foda, Wadelai.

This race appears just to enter the southern limits of the Anglo-Egyptian Sudan.

The races of G. nuchalis appear to be :— 1. G. N. NUCHALIS Gray, op. cit. Only known from the 5th Cataract. A small race with a wing of 140 mm., and with white borders to the.bases of the outer webs of the secondaries. Neck-band white.
