cisct hemg a synonvm. It extends from Sénégal to Southern Nigeria, 

 the Lagos birds proving to be examples of the tvpical form and not 

 of the Cameroon race. Neimann, however, considers the S. Nigé- 

 rian form slightlv intermediate between this and the following race 

 (efulenensis). We hâve, therefore, three well difFerentiated siib- 

 species inhabiting West and Central Africa, i. e. 



1. — CeNTROPUS l.EUCOGASTER I.EUCOGASTER. 



Cf. sitpra. 



Range. — Sénégal, Gambia, Portuguese Guinea, Sierra Leone, 

 Libéria, Gold Coast, Dahomey, Southern Nigeria. 



Observation. — In the British Muséum we hâve spécimens from 

 Sierra Leone, the Gold Coast and Southern Nigeria only. 



Distinguishing characters. — Head more green than the next 

 race: primaries, secondaries and wing-coverts chestnut; tail long 

 310-350 mm. 



2. — CeNTROPUS l.EUCOGASTER EFULENENSIS. 



Centropus efulenensis Sharpe, Ibis, 1904, p. 615 : Efulen, Came- 

 roon, 



Range. — Cameroon and Gaboon ; we hâve onlv spécimens from 

 Cameroon. 



Distinguisliing chai aciers. — Innir secondaries and primaries 

 darker; tail less barred ; size large, vving over 200 mm. ; tail shorter 

 240-270 mm. 



Observation. — Reichenow does not uphold this race. I ani 

 certainly going to recognise it until Sharpk is proved to be wrong, 

 as the only two spécimens in the British Muséum plainly show the 

 characters he assigned to this form.
