243 Hans, Graf von Berlepsch on the 



Prof. Cabanis has already adopted the term cyanomelas of 

 Gmelin for the D. cay ana of authors ; and I think he is 

 quite right in doing so. 



Fringilla cyanomelas, Gm. Syst. Nat. (ed. xiii. 1788) p. 924, 

 no. 93, is based on Koelreuter^s " Fringilla carulea, mento, 

 gula etc. nigris," described in Nov. Comment. Petrop. xi. 

 (1767) p. 434, and figured there, tab. 15. fig. 6 (no locality 

 given) . Koelreuter^s description and plate accurately repre- 

 sent the D. cayana auctt. (which I know from having care- 

 fully studied it), and has nothing to do with Ccereba ccerulea, 

 to which Mr. Cassin (Proc. Acad. Nat. Sci. Philad. 1864, 

 p. 266) incorrectly refers it. 



Finally, I may remark that "Blue Manakin,^^ Edwards, 

 pi. 263, and Dacnis nigripes, Cass, (nee Pelz.), Proc. Acad. 

 Philad. 1864, p. 269, are also synonyms of D. cyanomelas 

 (Gm.)"^, and have nothing to do with D. nigripes, Pelz., which 

 is quite distinct from it. 



3. Dacnis plumbea (Lath.), auctt. plur., ought to be called 

 D. bicolor (VieilL). 



I scarcely need repeat on this subject what Cassin (Proc. 

 Acad. Philad. 1864, p. 270) has pointed out, that Latham's 

 very short description (without any indication of locality) 

 of his Sylvia plumbea is barely applicable to this species of 

 Dacnis, for which Vieillot's name " bicolor " (first published 

 in 1807, Ois. Am. Sept. ii. p. 32, pi. 90. figs. 1 & 2, and then 

 in Nouv. Diet. xi. p. 167, where " Amerique Sept. et Cay- 

 enne " is given as the habitat) should be used. 



4. Chlorophanes atricapilla (VieiU.) , auctt. plur., ought 

 to be called C. spiza (Linn.) . 



In regard to this species I shall proceed in the contrary 

 direction and propose to bestow an old name upon a bird 

 now mostly called by Vieillot's denomination. As an apology 

 for so doing, I may remark that the Linnsean appellation 



* I have worked out very carefully the synonymy of this and other 

 species of Coerebida), it having been at one time my intention to prepare 

 a monograph of this family. The synonymy of some of the species is 

 very intricate.
