There is an excellent figure in Heuglin’s Orn. Nordost-Afr. pl. xxxi. of a very fine-looking Bustard of the size of O. cafra, with a black face, throat, and crop, and a red back to the neck.

Ogilvie-Grant in ‘The Ibis,’ 1902, pp. 453-457, renamed this bird Lissotis lovati, as was pointed out by Oberholser, P.U.S. Nat. Mus. xxvii. 1905, p.836. Both, however, agreed that there were two species, one with much white on the wings and one with little, and Oberholser named the latter Lissotis notophila, fiximg Durban as the type-locality. On examining the material in the Museum, however, we found that a series of these Bustards from Natal and elsewhere collected by Claude Grant, and which Mr. Ogilvie-Grant had not seen when writing his paper, had since arrived in the Museum. These show at once that the South African form has also SHR, X0-—VOL. If. Ou
