In the paper cited, Neumann lists various other spécimens from 

 Southern Nigeria now in tlie Tring Muséum, obtained at Degama 

 and Oguta. He notes that he can find no distinction between birds 

 froin the lovver Niger, ihe ishmds oi the Gulf ol Guinea, the 

 Ogowe river and Uganda. Since this was written, however, Boyd 

 Ai.EXANUER has obtaned a fine séries from Princes' Island and 

 there is no doubt that this bird nanied bv him F. princeps must be 

 kept distinct (cf. Ibis, 1914, p. 618). 



Until \ve hâve much more material I consider it best to recognise 

 ail the four forms of P. crithacus, i. e. 



1. — PSITTACUS ERITHACUS ERITHACUS. 



Cf. supra. 



Range. — Gold Coast, S. Nigeria, Gaboon, Benguella, Uganda. 



N'oie. — Spécimens of this Parrot s/iot i>i their native habitat 

 are badlv required in Muséums in Europe. 



2. — TsiTTACUS ERITHACUS TIMNEH. 



Psittacus timneh Fraser, P. Z. S., 1844, p. 38 : Sierra Leone. 



Distinguishing characters. — V^erv much darker colouring than 

 P. e. erithacus, and even darker than P. e. princeps. 



Range. — Sierra Leone, Libéria. 



3. — Psittacus erithacus princeps. 



Psittacus princeps Alexander, Bull. B. O. C, XXIII, 1909, 

 p. 74 : Princes' Island, Gulf of Guinea. 



Range. — Princes' Island, Fernando Po. 



Distinguis/mig characters. — Darker grev throughout .than 

 typical species; under-parts more purple; cf. mv remarks on 

 size, etc., Ibis 1914, pp. 618-620.
