Conservator. 
The Ornithological Section. 
During the past year the Conservator has devoted his attention 
mainly to a rearrangement of the study collection of bird skins which 
had become overcrowded through the large accessions of the past 
two years. 
Ten additional moth-proof cases have been procured, which have 
permitted a thorough rearrangement of most of the Passeres and 
Picariae, and the necessary relabelling of the trays has been completed. 
A large number of recently acquired specimens, temporarily arranged 
in wooden cases, have been interpolated in their proper places and 
catalogued. 
But little progress was made in the transfer of the mounted collec- 
tion to its new quarters, owing to the fact that the new cases were not 
completed until the close of the year; but with those now available 
and others in the course of erection, the transfer of the remaining 
specimens should be practically completed during the coming year. 
Among the important accessions during the past year are the series 
of 500 birds from British East Africa deposited by Mr. George L. Har- 
rison, Jr., and the collection of Lower Californian birds obtained by the 
Rhoads expedition, upon each of which the Conservator has prepared a 
report for the Academy’s Proceedings. 
A large number of the African birds were entirely new to our collec- 
tion, many of them having been discovered during the past decade. 
Another accession of note was a series of winter birds from South 
Carolina and of breeding specimens from New Hampshire, received 
from Mr. Nathan Clifford Brown, the specimens being exquisitely 
prepared in his well-known manner. 
The Delaware Valley Ornithological Club has added several speci- 
mens to its collection of local birds, including a section of tree trunk
