34 PROCEEDINGS OF THE ACADEMY OP 



head. Under parts yellow, clear and deeper on the throat ; breast and middle 

 of the abdomen tinged with greenish on the sides and flanks ; under tail corerts 

 pale yellow ; exposed end= of secondary quills chestnut brown ; primaries edged 

 with greenish yellow on their outer webs. Bill dark, both mandibles tipped 

 and with their cutting edges white ; legs light bluish. 



Sexes very nearly alike, females slightly smaller. 



Hah. River Muni, Western Africa. Discovered by Mr. P. B. DuChaillu. 



This is a small straight billed species belonging to the same group as our 

 T. noiaiiis and T. canicapillus, Hartlaub. It may be easily distinguished by its 

 straight bill and chestnut colored tail, both of which characters strongly mark 

 all of the specimens now before me, through some are evidently not in adult 

 plumage. 



The present bird appears to be allied also to T. olivaeens, Swainson, and to 

 T. icterinus, Temm. Bonap. Cons. Av. p. 262. It is, however, but a distant rela- 

 tive of T. barbaius, Temm. PL Col. 88, not belonging to the same subgeneric 

 group, and the description of T. icterinus, consisting as it does simply of a state- 

 ment : " Similis Tr. barbato, sed diiplo minor," is too careless and indefinite to be 

 entitled to any consideration. 



Six specimens have been received from Mr. DuChaillu, five of which are in 

 the present collection and one in that from the River Moonda, formerly received. 



8. Ixos ASHANTEUS, Bouaparte. 



Ixos ashauteus, Bonap. Consp. Av. p. 266. 



9. Andropadus latirostris, Strickland. 



Andropadus latirostris, Strickl., Proc. Zool. Soc, London, 1844, p. 100. 



Fraser, Zool. Typ. pi. 35 ? 



Very fine adult specimens, with the yellow stripe on each side of the throat 

 strongly marked. Sexes alike. I am not quite sure that Mr. Fraser's plate as 

 above represents this species. 



10. Andropadus virens, nobis. 



Smaller than either A. gracilirostris, latirostris or imporiimvs, but most resem- 

 bling the last. Bill wide at base, rather short, cutting edge of the upper man- 

 dible distinctly crenated near tbe tip ; wing moderate, rounded, fourth and fifth 

 quills longest and nearly equal ; tail rather short, with the feathers wide, plu- 

 mage of the rump long, ample, soft ; feet moderate. 



Total length, about 6 inches, wing 3, tail 2| inches. 



Colors generally resembling those of ^. i7}iportunus, but with the tail in the 

 present species dark greenish brown. Entire plumage above dark olive green, 

 rather lighter on the rump ; upper tail coverts tinged with brown. Under parts 

 yellowish green, the yellow predominating on the middle of the abdomen and 

 under tail coverts. Inferior coverts of the wing light greenish yellow ; quills 

 edged on their inner webs with yellowish white. Tail greenish brown with the 

 feathers slightly edged with yellowish green. Bill dark ; legs light colored. 



Hab. Cape Lopez and River Muni, Western Africa. Discovered by Mr. P. B. 

 DuChaillu. 



This is a smaller species than any hitherto known of this genus. It resembles 

 in general appearance .4. importunus, but can at once be distinguished by its 

 smaller size and the more decided brown color of its tail, in which character it 

 is more like the other two species mentioned above. This bird and A. graci- 

 lirostris and latirostris are evidently abundant species of Equatorial Western 

 Africa, numerous specimens of each being in the collections of Mr. DuChaillu. 



11. Platystira MELA.NOPTERA, (Gmelin.) 



Muscicapa melanoptera, Gm. Syst. Nat. i. p. 939, (IVSS.) 



Buff. Pl. Enl. 567, fig 3 ; Jard. & Selby, 111. Orn. i. pi. 9. 



Evidently an abundant species throughout Western Africa. 



The present collection contains a specimen marked as a young female which 

 has the throat and breast white, with only a few spots of the chestnut of the 

 adult.
