Localisation of specimens examined (closed symbols) and particular records (open symbols) of Nectarinia adelberti and TV rubescens in western Africa. V N. a. adelberti, A N. a. eboensis, ⦠TV r. crossensis, ⢠TV r. stangerii, â TVr. rubes- cens. the species except for extreme western Cameroon and Fernando Po. This sunbird is chocolate brown all over except for a metallic forehead cap, re- flecting greenish (front), lined with a purplish band backwards; metallic col- oured malar stripes and a metallic green coloured breast, again with a pur- plish edge towards the belly. The females are virtually indistinguishable from those of adelberti. In the birds on Fernando Po (stangerii Jardine) females have heavier breast-streaking than continental specimens. I have seen 2 adult female birds collected by Prof. M. Eisentraut (ZFMK , ) and compared with much material from Cameroon and Zaire and think that indeed the race can be accepted, although the males are identical in colouration to mainland birds (see also Amadon, 1953 and Eisentraut, 1973 with whose findings I agree). The name TV r. crossensis (Serle, 1963) was proposed for two male and one accompanying female specimens from the localities Mamfé and "West of Ba- menda", both in western Cameroon; males differing only from nominate birds in lacking the metallic breast colour, this one being replaced by the same dark brown as present on other parts of the bird. These birds, said to require confirmation as a separate race by White (1965) and Eisentraut (1973), form the key in the following discussion. The two male birds are fully adult. It must be stressed that the metallic breast is one of the first adult male characteristics that is developed in rubescens. Therefore it is exclu-. Please note t
