species. It seems quite absurd to call a group of birds occurring 

 only in the Moluccas " Mascarinus." I therefore suggest the adop- 

 tion of the term " Poli/chlorus," given by Scopoli as the specific de- 

 signation of Psittacus maynns, as a generic name for these birds — 

 "which will so stand as PoIycJdorus magnus, and Polychlorus Ff^esfer- 

 nianni ; and the third species, Prince Bonaparte's Psittacodis in- 

 tennedhis, of which there are examples in the British and Leyden 

 Museums — as PolycMoi'us intermedins. 



It is singular that the only other known example of Polychlorus 

 Westermanni, from which Prince Bonaparte's description was taken, 

 is also a living bird in the Zoological Gardens of Amsterdam, where 

 the collection of Psitfacidee (which I had the pleasure of inspecting 

 a few weeks since) is very good, embracing about sixty-four species. 



It is however surpassed by that in our own Gardens, where at the 

 present moment no less than seventy-five species may be seen living.
