70 Macrosphenus flavicans, nobis.

 dark greenish cinereous, throat and neck in front light cinereous. Body above 

 light olive greeu, below greenish yellow inclining to saffron yellow on the 

 flanks, tibia yellow, mixed with cinereous in its lower third. Under wing 

 coverts silky white, quills brownish black, edged externally with ashy olive, 

 tail olive green, darker on the inner webs. Bill bluish horn color, under man- 

 dible white at base, and viewed from below, having a longitudinal stripe of 

 white throughout its length, legs light colored. Total length about 5 inches, 

 wing 2, tail If, bill from gape f, tarsus J inches. 



Hub. Camma River, Western Africa. Discovered by Mr. P. B. Duchaillu. 



The affinities of this bird, and that alluded to above, as probably from 

 Madagascar, I have not satisfactorily determined. The general aspect is that 

 of Orthotonus and Ramphoccenus, as stated above, but they appear also to be 

 related to Tatare, Lesson, and in fact have the bills very similar to that of 

 Tatar e lusdnius or Thryothorus luscinius, Quoy et Gaiin. Voy. Astrolabe, Ois. 

 pi. 5. At present my opinion is that they belong to the group Troglodytince. 



Several specimens of this bird are in the collection from the Camma, all of 

 which are labelled as males. 



71. Turdus pelios, Bonaparte. 



Turdus pelios, Bonap. Consp. Av. i. p. 273, (1850.) 

 Though with numerous specimens before me, of both sexes and various ages, 

 I rely on labelled specimens in the Acad. Mus. more than descriptions in the 

 determining of this species. The specimens alluded to are labelled in the 

 handwriting of that very competent naturalist, Mr. Jules Verreaux, and are 

 quite identical with those in the present collection. This species is nearly 

 related to T. libonyanus, Smith, of Southern Africa, and appears to be abundant 

 on the Camma, Moonda and Muni rivers. 



72. Cossypha poexsis, Strickland. 



Cossypha poensis, Strickl. Proc. Zool. Soc. London, 1844, p. 100. 

 Fraser, Zool. Typ. pi. 37. 



Specimens from the Camma which seem to be the species described and 

 figured as above, in adult plumage. 



73. Cossypha verticalis, Hartlaub. 



Cossypha verticalis, Hartl. Beitr. Cab. Jour. 1855, p. 22. 



Petrocincla albicapilla, Swains. B. of W. Afr. i. p. 2S4, pi. 32 ? 

 The only specimens that I have ever seen from Equatorial Africa are in the 

 collection from the Camma, and are darker in the color of the upper parts of 

 the body than specimens from Senegal in the Acad. coll. In fact I would de- 

 scribe the back and wing coverts in these specimens as black in the adult and 

 brownish black in the young, though, in other respects, specimens from the 

 localities mentioned are very similar. * 



74. Geocichla compsonota, nobis. 



About the size and general form of Turdus interpres, Temm. PI. Col. 458, 

 but does not resemble that species in colors. Tail short, wings moderate, 

 first quill spurious, fourth and fifth longest, legs rather strong, toes rather 

 long, bill straight, rather thick, upper mandible curved at the tip and distinct- 

 ly notched. Head above, cheeks and small space on the chin dark cinereous, 

 upper parts of body and wing coverts bright rufous, quills brownish black, 

 the two first edged externally with dark cinereous, others and especially the 

 shorter quills widely edged with the same bright rufous as the back, tail 

 brownish black, outer feathers edged with rufous. Under parts (except a 

 small space on the chin) white, tinged with dull yellowish brown on the breast 

 and flanks. Bill bluish black, legs pale yellowish (in dried skin.) Total 

 length about 6 inches, wing 4f , tail 2^, tarsus 1, bill from gape f inches. 



Hab. Camma river, Western Africa. Discovered by Mr. P. B. Duchaillu.
