Bannerman, Ibis, 1912, p. 244), and therefore preoccupies 

 the Chalcites smaragdineus Swains. (Birds W. Afr. vol. ii. 

 1837, p. 191) : Gambia ; which locality I designate for 

 Shaw's name. 



^y adopting Boddaert's name as spelt, and thus allowing 

 Shaw's name to stand for the Emerald Cuckoo, the whole 

 nomenclature of these two Cuckoos is in my opinion simpli- 

 fied, and the only real alteration that takes place is in placing 

 C. smaragdineus Swains, as a synonym of C. cupreus Shaw. 



Mr. W. L. Sclater, whom I have consulted on the point, 

 thinks with me that this change to strict priority places the 

 names and original descriptions on a better basis. 



I agree with Bannerman that Reichenow's Metalococcyx is 

 synonymous with Boie's Chrysococcyx (cf. Ibis, 1912, p. 245).

Prof. Neumann, in the Bull. B.O. C. vol. xii. 1902, p. 75, 

 records that be has examined the type of Cuculus nigrorufus 

 Cuv. (Reg. Anim. vol. i. 1817, p. 426, which was founded on 

 plate 220 of Levaillant, Ois. d'Afrique, vol. v. 1806, p. 78 : 

 Swart River, Cape Colony), and that " the species proved to 

 be not an African bird, but the bird afterwards called 

 Centropus purpureus" which was described by Shelley in 

 the Catalogue of Birds in the British Museum, vol. xix. 1891, 

 p. 348, from Sumatra. 



Levaillant's plate certainly agrees better with the Suma- 

 tran bird than it does with the African, and I therefore, 

 under the circumstances, support this re-distribution of 

 names ; this re-arrangement was apparently first proposed
