Ceriocleptes proposed by Mr. Cliapiii^ but I consider that it 

 must be kept up. 



If Keichenow^s genus Melichneutes (Orn. Monatsl). 1910, 

 p. 160), founded on M . sommerfeldi, is, as I suspect, identical 

 with Chapin's genus Ceriocleptes, then E/eichenow's name 

 will take precedence. 



Prodotiscus insignis. 



Hetarudes insiyuis Cassiti, Proc. Acad. Philad. 1856, p. 157 

 — Type locality : Moonda River, Gaboon. 



'^Prodotiscus eimni Shelley, P. Z. S. 1888, p. 43 [Bellima]. 



Two advilt female examples procured by Mr. Bates at 

 Bitye, River Ja, should be typical examples of Hetcerodes 

 insignis Cassin, described from tlie Moonda River, Gaboon. 

 It seems more than probable that the ty[)e specimen of 

 P. emini Shelley (which came from Bellima iu the Tingasi 

 District and not from Wadelai as stated in the original 

 description, cf. P. Z. S. 1888, p. 43) is a male o£ the present 

 species. In the British Museum collection there is a female 

 exam])h' from Nairobi, presented by Mr. A. B. Percival, 

 which nearly resembles one of the adult females sent by 

 Mr. Bates. He also sent a quite young female with the 

 quills half-grown from the same locality. It would seem 

 that the species ranges from the Lake District to West 

 Africa, but our very small series does not afford sufficient 

 evidence to determine this. 



Cuculus gaboiiensis gabonensis. 



Cuculus gaboneiisis Lah-esunyc, Rev. et Mag. Zool. 1853, 

 p. 60 — Type locality : Gaboon ; Sharpe, Ibis, 1907, p. 436 ; 

 Bates, Ibis, 1911, p. 500.. 



The valuable material now sent home by Mr. Bates, 

 together with his notes on this species published in 'The Ibis' 

 for 1911, throw considerable light on the complex plumage 

 changes which the Gaboon Cuckoo undergoes between the 

 stage of nestling and adult. Mr. Bates has already pointed 

 this out, Ijut his remarks are of such value that I wish to 

 emphasise them again.
