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 Gmelin^s namOj 
Motacilla multicolor, for D^Aubenton^s ^Figuier noir etjaune 
de Cayenne^ (PI. Enl. 391. f. 2)—an older title for which is 
Motacilla tricolor a, Miill. (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 Bed-bellied 
Flycatcher of Latham, a bird now known as Petroeca multu 
color, and which comes from Australia. In the absence of 
all trace of a species of Setophaga in Mexico answering tp 
Bonaparte^s diagnosis, I am inclined to think that he took his 
characters from a specimen of Petroeca 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 genns.
