1921.] On the Genus Macrosphenus Cassin. 
genus (Ibis, 1916, pp. 1-16). Mr. Bates lias remarked on 
the back of one of his labels that lie believes the species 
named H. plumbescens Sharpe is identical with H. simplex , 
but he will see in my paper cited that this is not the case. 
H. s. simplex is restricted to the island of St. Thomas in the 
Gulf of Guinea (cf. Ibis, 1915, p. 119). I should like to 
take this opportunity to correct an error which appeared in 
my review of this genus (/. c.). On pp. 11 and 14 I gave 
the same range for both Huplopelia simplex inornata and 
H. s. plumbescens. It should be as follows :— 
H. s. inornata. 
Range. Cameroon Mountain. 
H. s. plumbescens. 
Range. Southern Cameroon (except Cameroon 
Mountain), River Ja distinct. 
Aplopelia tesmanni Rchw. described from Behai, S. Came¬ 
roon, is synonymous with H. s. plumbescens. 
V.— On the Genus Macrosphenus Cassin , with special 
reference to the races of Macrosphenus flavicans. By 
David A. Bannerman, M.B.E., B.A., M.B.O.U. 
The type of the genus- Macrosphenus is M. flavicans of 
Cassin (Proc. Pliilad. Acad. 1859, p. 42), and this species 
was described from the Camma River, Gaboon. 
Macrosphenus flavicans flavicans Cassin. 
From material in the British M useum I consider that this 
species, of which we have seventeen examples in the. British 
Museum, extends from western Cameroon, through Gaboon 
to Landana at the mouth of the Congo, and I also unite 
with it Macrosphenus poensis of Alexander (Bull. B. O. C. 
xiii. 1903, p. 36) which inhabits Fernando Po, as I cannot see 
any distinction between this and the mainland bird. It is 
also evident, as suggested by Sharpe and confirmed by 
Ogilvie-Grant (Trans. Zool. Soc. xix. 1910, p. 378), that 
Macrosphenus zenkeri Reichvv. (Orn. Monatsber. 1898, p. 23),
