NATURAL SCIENCES OF PHILADELPHIA. 87 



An obscure species, of which two specimens only are in the collection from 

 Mr. Duchaillu, one in the present collection and another formerly from the 

 Moonda. In the Acad. Mus. are several specimens from the Rivoli collection, 

 all of which are labelled ' ' Cinnyris cyanocephala, $ . " It may be that species 

 jn immature plumage, or in the plumage of the rainy season.* 



47. Anthreptes Fraseri, Jardine and Selby.

Several specimens of this species are in the present collection from the Camma 

 and Ogobai. The adult is well represented and described in the work cited 

 above, though in the figure the tail is quite erroneous. The middle feathers 

 of the latter are greenish yellow, which is also the color of the outer webs, and 

 a large portion of the inner webs of all the other feathers of the tail. 5 

 Smaller than the male but very similar in colors. Young 5 Like the female, 

 but with the colors duller and of darker green in all the plumage, no axillary 

 tufts. 



48. Anthreptes aurantia, Verreaux. 



Anthreptes aurantia, Verr. Rev. et Mag. Zool. 1851, p. 417. 

 The adult male is described by our valued friend as above cited, and the 

 type of his description is now in the Museum of this Academy. The female 

 is so entirely different that it might readily be regarded as a distinct species. 

 Adult 2 Upper parts lustrous metallic dark green, purple on the rump 

 and tail, throat and breast pale ashy, abdomen pale yellow. A stripe of white 

 through and behind the eye. Young 5 . Upper parts dull yellowish green, 

 under parts pale yellow, tinged with very pale asby on the throat, very dis- 

 tinct stripe of pale yellowish white through the eye, tail metallic green, outer 

 feathers tipped with dull white. From the Camma and Ogobai. 



49. Drymoica ruficeps, (Riippell.) 



Malurus ruficeps, Riipp. Zool. Atlas, p. 54, (1826.) 

 Riipp. Zool. Atlas, pi. 36, fig. 1. 



Several specimens from the Camma and Ogobai seem to be this species, but 

 are rather larger than South African specimens in the Acad. Mus. 



50. Drtmoica njevia, Hartlaub. 



Drymoica naevia, Hartl. Orn. W. Afr. p. 56. 

 A single specimen from the Camma and another in a former collection from 

 Cape Lopez, appear to be this species, though not in adult plumage. Related 

 to the preceding, but larger and with the bill much stronger ; and also related 

 to the succeeding. 



51. Drymoica fortirostris, Jardine. 



Drymoica fortirostris, Jard. Contr. Orn. 1852, p. 60. 



Drymoica robusta, Riippell, Syst. Uebers. p. 35, pi. 13? 

 From the Camma and formerly received from Cape Lopez. In a young bird 

 the bill is pale yellow, except the tip of the upper mandible. The birds re- 

 garded by me as the present species and the preceding (D. ncevid) are both 

 nearly related to D. robusta, Riippell, Syst. Ueb. pi. 13. 



52. Drtmoica lateralis, Fraser. 



Drymoica lateralis, Fras. Proc. Zool. Soc. London, 1843, p. 16. 

 Numerous specimens from the Camma, Moonda and Muni rivers appear to 

 be this species, though utterly impossible to determine satisfactorily from the 

 published descriptions. It seems to be the most abundant species of this 

 genus in Equatorial Western Africa. 



*Two other species complete the Nectarinice, found by Mr. Duchaillu : 



1. Nectarinia superba, (Vieillot), from the river Muni. 



2. Nectarinia Johannae, Verreaux, from the river Moonda.
