Mr. O. Salvin^s Synopsis 
I am not sure that some of the distinctive characters of 
j 8. castaneocapilla may not he traced to the immaturity of 
the specimen; hut this can only he proved hy the acquisition 
of more specimens. 
8. castaneocapilla is one of the interesting species which, 
with many others, should he looked for carefully hy any 
traveller who, treading in Schomhurgk^s steps, may visit the 
Eoraima Mountains and the rest of the little-explored interior 
of British Guiana.

The specimen from which the above description and the 
accompanying figure were taken was obtained by Mr. T. K. 
Salmon at Santa Elena, in the Columbian state of Antioquia, 
two other similar examples being in Mr. Sclater^s collection. 
At one time we thought that they might be 8. flaveola in 
adult dress; but the restriction of the yellow of the occiput 
to the anterior portion of the head, and other points, prove 
that this view cannot be maintained. Moreover, a comparison 
of a sketch of the head of 8. flaveola, taken from the type, 
both with the bird now described and with specimens of 8. 
ornata, leads me to the conclusion that Lafresnaye^s type of 
8. flaveola is but an immature specimen of the latter bird. 
The specimen in the Derby Museum, called 8. flaveola by 
Kaup, agrees very closely with Mr. Salmon^s examples. The 
anterior ear-coverts, however, are darker—a character which, 
I believe, indicates that this specimen is not so old as the 
Santa-Elena bird. The Derby-Museum specimen was ob¬ 
tained by the French collector Delattre on the Paramo of 
Popayan, and is marked male.^^ The range of 8. chrysops 
would therefore appear to be restricted to the mountains 
forming the eastern boundary of the valley of the river Cauca*
