14. DescrIPTIONS OF SEVENTEEN NEw SPECIES OF BIRDS FROM 
Costa Rica. By Osspert Satvin, M.A. 
(Plates XXXV., XXXVI.) 
The following seventeen birds I have selected, as apparently un- 
described, from a collection lately sent to Mr. Godman and myself 
from Costa Rica, where it was made by a former collector of ours in 
Guatemala, Enrique Arcé, a native of the latter country. Early in 
the present year, with the kind assistance of Capt. J. M. Dow, Arcé 
left Guatemala, and, after forwarding a small collection from the 
Pacific slope, crossed over to the valleys of the eastern coast; and 
it is from this latter district that the following birds have been prin- 
cipally selected. The remainder of the collection comprises many of 
the rare types described a few years back by Cabanis, and also several 
Humming-birds, M. Warszewicz’s discoveries in Veragua. I am 
now acquainted with about 304 species (mostly Passeres) from this 
country, no less than about 65 of which have been described by 
various authors as new, and which have not as yet been found be- 
yond the limits of Costa Rica or the immediately adjoining province 
of Veragua. Arcé is continuing his labours; and I hope ere long 
that through him and Dr. von Franzius, from whom Prof. Baird of 
Washington is receiving collections, that this most interesting country 
will be thoroughly explored. In determining thése species, I ac- 
knowledge the kind aid of Mr. Sclater and Mr. Gould, and the ad- 
vantage of free access to their collections.
