migrant. Unfortunately all our si)ecimens lia|)pen to be 

 winter birds, and Mr. Butler looked on it also as only a 

 winter migrant. We liave, 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. jiUleborni of south- 

 eastern Africa, which is undoubtedly a resident race.

Glareola (Galachrysia) nuchalis nuchalis. 



Glareola nuchalis Gray, P. Z. S. 184D, p. 63, pi. 9 : 5th 

 Cataract of tlie Nile. 



This bird, only known from the type, was secured by 

 Galton at tlie 5th Cataract near Berber, and the British 

 Museum Catalogue of Birds is therefore Avrong in giving 

 the Up[)er 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 iutergrade, and they are 

 therefore best considered as one species.
