Recently published Ornithological Works. 383 
rufas , and Numenius tenuirostris are now figured for the 
first time ; while those of Turdus naumanni are refigured, as 
there appears to have been some uncertainty in the case of 
former specimens. 
The text requires but little comment, though we may 
remark that, while Mr. Dresser’s pages were in the press, 
Dr. Sclater exhibited an egg of the Great Shearwater, 
hitherto unknown, from Tristan da Cunha ( cf . Bull. B.O.C. 
vol. xxii. p. 22), and that the record of the Sooty Shearwater 
from the Forth area should be attributed to W. Evans 
instead of A. H. Evans. 
The plates are, as usual, excellent, though perhaps the 
Guillemot’s eggs might have been rather brighter, and we 
feel quite sorry to bid farewell to such a fine series of illus¬ 
trations, accompanied as they are by Mr. Dresser’s careful 
and accurate information. 
36. Ferry on Birds from Costa Rica. 
[Catalogue of a Collection of Birds from Costa Kica. By J. F. Ferry. 
Field Museum of Nat. Hist. Ornithological Publ. i. no. 6. Chicago, 
1910.] 
Mr. J. F. Ferry, Assistant in the Ornithological Depart¬ 
ment of the Field Museum of Natural History at Chicago, 
made an excursion to Costa Bica in the spring of 1908, and 
collected birds in various localites on the Atlantic slope 
of that country. In the present memoir, after a preface 
containing an account of the places where he stopped, 
the author gives a list of the species represented in the 
collection which he made, some 120 in number, accompanied 
by short field-notes. None of these species are new, but some 
of them are of interest. The difficult forms were referred 
to the National Museum for exact identification. 
A nest of the Quezal ( Pharomacrus mocinno costaricensis ) 
was found in a dead stump standing in partially cleared forest, 
some twelve feet from the ground, but it was unfortunately 
empty. 
We think that our American friends, when they use new 
and little-known terms such as Semnornis , Pselliophorus , &c.,
