1 92 1.] On the Genus Macrospheuus Cassin. 121 



genus (Ibis, 191(5, \)\). 1-16). JNlr. Bates has remarked on 

 tJie back of one of his hibels that he believes thd species 

 named H. plumbescens Sliar[)e is identical with H. simplex, 

 but he will see in my p;iper cited that this is not the case. 

 //. s. si)iij)lex is I'estrictcd 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. IT and 14 I gave 

 the same i-angc for tjoth Haplopelia simplex inornata and 

 7/. s. plumbescens. It should be as t'oUows : — 



H. s. inuniuta. 



Range. Cameroon ^Mountain. 

 II. s. plumbescens. 



Raiifje. Southern Cameroon (except Cameroon 

 Mountain). l\i\er Ja district. 



Aplopcliu tcsmunni Rchw. described from Bebai, S.Came- 

 roon, is synonymous with H. s. plumbescens. 



V. — On the Genus Macrospheuus Cassin, with special 

 reference to the races of Macrospheuus flavicans. By 

 David A. Bannerman, M.B.E., B.A., M.B.O.U. 



The type of the genus Macrosphenus is M. jiavicans of 

 Cassin (Proc. Philad. Acad. 1859, p. 43), and this species 

 was described from the Camnui River, Gaboon. 



Macrosphenus flavicans flavicans Cassin. 



From material in the British Museum 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 1 also unite 

 with it Macrosphenus pocnsis of Alexander (Bull. B. O. C. 

 xiii. 1903, p. 30) 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 l^y 

 Ogilvie-Grant (Trans. Zool. Soc. xix. 1910, p. 378), that 

 Macrosphenus zcnkerl lieichw. (Orn. Monatsber. 1898, p. 23),
