the larsje amount of wliite on the wing, and is, as far as we 

 can see, inseparable from trne Otis melmiugaster Riip]). We 

 must tlierefore agree with lleichenow that tliere is only ot)e 

 species, and must place L. lovati O. -Grant and L. noto- 

 j)hila 01)erholser as synonyms. The only birds whicli 

 we can find which do not have the large amount of wliite 

 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-Graut, except for these two Nyasaland specimens, 

 one of which may very well have been the actual specimen 

 figured by hira. Further material from that country there- 

 fore 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 ouly 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.
