Evidently not very common in the countries traversed by Mr. Duchaillu. 

 Adult 9. Upper parts olive, tinged with yellow on the rump, under parts 

 greenish yellow, darker on the throat and breast, the yellow more clear on the 

 abdomen. 



From the Camma.

This appears to be an abundant species in Equatorial Africa on the Atlantic, 

 and seems to have a wide diffusion. Young % . Like the female, but with the 

 under parts more strongly tinged with yellow, and with the top of the head 

 dark brown. In this species the young birds have the under mandible white 

 at base, and frequently for half or two-thirds of its length, which is not the 

 case in the allied species immediately succeeding (jV. cyanolcema). From the 

 Camma and Ogobai, and formerly received from the Moondaand Muni rivers. 



42. Nectarinia cyanolaema, Jardine. 



Nectarinia cyanolaema, Jard., Contr. Orn. 1851, p. 154. 

 Young '8 . Upper parts dark olive, tinged with yellow, under parts pale 

 yellowish green, with obscure spots of dark green, nearly black on the throat. 

 Bill always black. From the Camma, and formerly received from the Moonda 

 river. 



43. Nectarinia Reichexbachii, Hartlaub. 



Nectarinia Reichenbachii, Hartl. Orn. W. Africa, p. 50. 

 Several specimens from the Camma appear to be this species, though rather 

 larger than as given by Dr. Hartlaub, as above. Young % . Like the female, 

 but with the throat, abdomen and under tail coverts yellow, the former with a 

 few lustrous metallic green feathers. 



44. Nectarinia tephrolaejia, Jardine. 



Nectarinia tephrolaema, Jard., Contr. Orn., 1851, p. 154. 



From the Ogobai and Moonda rivers. The description of the female given 

 by Dr. Hartlaub applies to young males in the present collection, but unfor- 

 tunately I am not fully assured of the correctness of the supposed females of 

 this species in this collection, and do not therefore describe with con- 

 fidence. The specimens alluded to are entirely dark ashy, (about the color of 

 the throat in the male,) darker above and lighter on the under parts. 



This appears to be a rare species in Equatorial Africa, and is remarkable in 

 having' the throat pale cinereous, though surrounded with a large space of 

 brilliant metallic green. It is probably the type of a subgenus and does not 

 belong to the same group as the preceding (iV. cyanolaema,) though given so, 

 erroneously, by Dr. Reichenbach in his genus Anthodiceta. This author is, 

 however, not acquainted with the genera of birds. 



45. Nectarinia sdbcollaris, Reichenbach. 



Nectarinia subcollaris, Reich. 



N. metallicus, Licht.? 



N. collaris, (Vieill.) ? 

 Specimens in the collection are evidently the species intended by the name 

 here adopted ; but with numerous specimens before me purporting from Euro- 

 pean labels to be N. collaris and N. metallicus I am under the necessity of enter- 

 taining a suspicion that all are identical. These specimens are perhaps not 

 correctly labelled, but at present my leisure does not warrant an extended ex- 

 amination. These species are assuredly very nearly related. From the Camma. 



46. Nectarinia verticalis, (Reichenbach.) 



Leucochloridia verticalis, Reich. 



"Nectarinia Vieilloti, Verreaux." Label of spec, in Acad. Mus.
