1,409 skins, have been labeled and catalogued. For this work 
the Conservator is largely indebted to Mr. Howard Y. Pennell. 
The additions to the ornithological collection during the year 
have been noteworthy. The Rhoads collection of British Columbian 
birds, numbering about 1,100 which was generously pur¬ 
chased by friends of the Academy, is of especial importance as it 
comprises large series of specimens from a region hitherto unrepres¬ 
ented in the museum. Through the liberality of friends of the in¬ 
stitution the Section was enabled to have an experienced collector, 
Mr. R. B. Herron, in the field for a short time in the vicinity of 
San Bernardino, Southern California, and many valuable specimens 
of species heretofore wanting or very poorly represented in the col¬ 
lection were obtained. 
The collection of mounted birds of the late George W. Carpenter 
is also a very valuable acquisition, containing examples of many 
rare species, the most important of which is an adult male speci¬ 
men of the extinct Labrador duck. 
The Delaware Valley Ornithological Club has also added many 
very instructive groups of native birds with their nests and eggs, to 
the already large collection presented during previous years. 
This is now one of the most attractive exhibits in the museum.
