of the Genus Setophaga. 321 



and fro. Subsequently our Indian hunters used not unfre- 

 quently to bring us specimens from the same district ; but 

 nowhere else did we meet with it, nor am I aware that spe- 

 cimens are ever included in the large collections sent home 

 from time to time from Vera Paz. 



Many species of various genera have from time to time been 

 placed in the genus Setophaga, but have since been relegated 

 to their proper systematic positions ; so that I need not refer 

 to them here. One species, however, calls for remark ; and 

 that is Setophaga multicolor, briefly described by Bonaparte 

 in his ' Conspectus Avium' (i. p. 312), from a specimen in 

 the Senckenberg Museum said to be from Mexico. It must 

 be observed that Bonaparte adopts with doubt Gmelm's name, 

 Motacilla multicolor, for D'Aubenton's { Figuier noir etjaune 

 de Cayenne' (PL Enl. 391. f. 2) an older title for which is 

 Motacilla tricolor a, Mull. (Natursyst. Suppl. p. 175). Judg- 

 ing from the figure, I should think it intended to represent 

 Setophaga ruticilla, a species already traced to British Guiana. 

 Bonaparte's diagnosis, however, hardly suits this figure, but 

 answers very well to Gmelin's description of his Muscicapa 

 multicolor (Syst. Nat. i. p. 944), founded on the Re*d-bellied 

 Flycatcher of Latham, a bird now known as Petrceca multi- 

 color, and which comes from Australia. In the absence of 

 all trace of a species of Setophaga in Mexico answering to 

 Bonaparte's diagnosis, I am inclined to think that he took his 

 characters from a specimen of Petrceca multicolor to which a 

 wrong locality had been attached. 



In conclusion, I beg leave to express my thanks to Mr. 

 Thomas Moore and the authorities of the Derby Museum of 

 Liverpool, and also to Professor Peters of Berlin, for the loan 

 of specimens which have helped me most materially in working 

 out the synonymy of this genus.
