kind enough to send me by post, the term Cichlopsis of Cabanis is 

 used generically for the Ptilogonys nitens of Swainson. Now I wish 

 to point out, that if this bird is to be constituted a separate genus 

 from Ptilogonys cinereus (for which there seem to be sufficient 

 grounds), Cabanis' name cannot be employed for it, as it is less 

 closely allied to the true type of his genus than to Ptilogonys. The 

 Cichlopsis was one of the many rare birds in the Berlin Museum 

 which the late Professor Lichtenstein (whose example in this respect 

 has, I am sorry to say, been followed in several other large collec- 

 tions) thought he had made sufficiently public, by labelling as 

 " Turdus leucogonys." Dr. Cabanis, in his " Museum Heineanum " 

 first shortly indicated the characters of this bird, and rightly assigned 

 it to the neighbourhood of Myiadestes, proposing for it the new 

 generic term Cichlopsis. But he made the mistake of writing Lich- 

 tensteiu's MS. name "leucogonys" (taken from its white under 

 mandible) " leucogenys," and so caused Prince Bonaparte to fall 

 into the error of considering it to be identical with Tschudi's Ptilo- 

 gonys leucotis, a very different bird. Prince Bonaparte's somewhat 

 curt description* of "Myiadestes leucotis," the third species of his 

 genus Myiadestes, as given in the 'Conspectus ' (p. 336), is doubt- 

 less intended for this species. I first became acquainted with this 

 curious type at Berlin, but was delighted at meeting with it again 

 at Philadelphia in the collection of the Academy of Sciences, as I 

 have already mentioned in these Proceedings f. Lately I have 

 picked up a specimen myself, which from its appearance I should 

 consider to be from Brazil — the locality assigned to it by Lichten- 

 stein. Prince Bonaparte has also described this bird in another 

 place as Myiocichla ochrata, and states it to be the type of Dr. 

 Schiffs' MS. generic term Myiocichla. Mr. G. R. Gray has, how- 

 ever, given the type of Myiocichla as Turdus jiavipes, Vieill. — a 

 typical Thrush. 



The somewhat complicated synonomy of this bird will, therefore, 

 stand as follows : —
