Show 1874.] MR. R. B. SHARPE ON NEW BIRDS 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 Camma, doubtfully referred by Mr. Cassin to the latter species, are really the young of C. anselli; and thus it is probable that C. francisci is confined to the Gold Coast. C. anselli 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. seneyaleitsis. 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. toidou. 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; forehead 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 m e the following birds :- A specimen of Coccystes jacobinus. W h e n I wrote m y paper on African Cuckoos I was not aware of any instance of the capture of this species in Western Africa. The Museum, however, now contains 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 :-Caprimu/gusfulviventris, Cos-sypha cyanocampter, Rallus oculeus, Musophagagigantea, Astur ma-croscclides, Accipiter melanoleucus, Polyboroides typicus. |
