1874.] MR. R. B. SHARPE ON NEW BIROS FROM GABOON. 205 



The measurements of this bird show that it is one of the largest of 

 the African Centropi, finding its nearest ally in C.francisci. Indeed 

 I suspect that the young birds from the Cam ma, doubtfully referred 

 by Mr. Cassin to the latter species, are really the youug of C. ansetti ; 

 and thus it is probable that C. francisci is confined to the Gold 

 Coast. 



C. ansetti wants the black throat of C. francisci, and is therefore 

 easily recognizable. Its large size, black tail, and the fulvous colour 

 of the lower back and rump sufficiently distinguish it from C. senega- 

 lensis and C. monachus. The discovery of this new species renders 

 the table given by me (P. Z. S. 1873, p. 617) imperfect; and I 

 therefore revise it. 



a. Abdomen whitish or buffy white. 

 a'. Throat white or buffy white. 



a". With no perceptible superciliary streak. 



a'". Head greenish black 1. senegalemis. 



b'". Head purplish blue 2. monachus. 



b". "With a broad whitish eyebrow 3. superciliosus. 



b'. Throat black 4. francisci. 



b. Abdomen chestnut. 



c'. Larger: throat chestnut 5. anselli. 



d'. Smaller: throat black 6. epomidis. 



c. Abdomen black. 



e'. Wing-coverts barred with black. 



c". Centre tail-feathers barred with fulvous 7. nigrorufus. 



d". Centre tail-feathers black 8. grilli. 



f. Wing-coverts rufous, not barred 9. toulou. 



The other species discovered Mr. Ansell is, so far as I can make 

 out, perfectly new to science, being a Dryoscopus with a rufous crown. 

 I therefore propose to name it 



Dryoscopus coronatus, sp. n. (Plate XXXIII. fig. 2.) 



Above glossy black, with a slight greenish gloss, the quills entirely 

 black, the greater wing-coverts tipped with white, forming a broad 

 wing-band, which is continued down the wing by means of a narrow 

 white edging to the inner secondaries ; head and nape chestnut ; fore- 

 head and a narrow superciliary line fulvous ; lores, sides of face, and 

 ear-coverts glossy black ; cheeks and entire throat and breast clear 

 chestnut fawn-colour ; abdomen, thighs, sides of body, and under 

 wing- and tail-coverts pure white ; bill and feet black. Total length 

 8 inches, culmen 1, wing365, tail 3"7, tarsus T3. 



Besides the two above described, Mr. Ansell has sent me the fol- 

 lowing birds : — 



A specimen of Coccystes jacobinus. When I wrote my paper on 

 African Cuckoos I was not aware of any instance of the capture of 

 this species in Western Africa. The Museum, however, now con- 

 tains two examples, as we have received it through M. Bouvier, 

 from Dakar in Senegal, and now Mr. Ansell sends it from Gaboon. 



Among the remaining skins forwarded by the latter gentleman 

 are the following interesting species : — Caprimulgusfulviventris, Cos- 

 sypha cyanocampter, Ra/lus oculeus, Musophaga gigantea, Astur ma- 

 croscelides, Accipiter melanoteucus, Polyboroides typicus.
