800 Messrs. Sclater and Mackworth-Praed on [ This, the large amount of white on the wing, and is, as far as we can see, inseparable from true Otis melanogaster Riipp. We must therefore agree with Reichenow that there is only one species, and must place L. lovati O.-Grant and L. notophila Oberholser as synonyms. The only birds whichi we can find which do not have the large amount of white on the wing are undoubtedly not fully adult, with only two exceptions, both from Nyasaland. There is, of course, some slight variation in the amount of white in adults from other parts of Africa, but nothing like the amount depicted by Ogilvie-Grant, except for these two Nyasaland specimens, one of which may very well have been the actual specimen figured by him. F[urther material from that country therefore will be of interest, but, should this difference prove consistent, the race will require a new name.

This Bustard ranges from Senegal to the Nile Valley, being most frequent in the red sandstone country of Kordofan. ‘This is the only specimen in the Museum from the Sudan, and it appears to be even redder on the back and with finer vermiculations than the examples from Senegal and Lake Chad. Whether this is individual or not we cannot say.
