810 PROCEEDINGS OF THE ACADEMY OF [DeC.*, 



the GalHnacese, or approximately half of the mounted collection, so 

 far as space occupied is concerned. 



The specimens transferred during the year have all been labelled 

 and have been carefully examined by the taxidermist, while the 

 entire series has been rearranged to bring it into systematic 

 sequence. 



Several old horizontal cases have been renovated and placed on 

 the ornithological floor for the accommodation of a special collec- 

 tion, prepared for exhibition by the Conservator, illustrating the 

 structure and molt of birds. 



The opening of this department to the public, unavoidably post- 

 poned, will take place early in the coming year. 



Two additional large wooden storage cases and sixteen tin cases 

 were provided for the accommodation of the rapidly increasing 

 study collection of skins, and much important work has been 

 accomplished in transferring the specimens to the new cases and in 

 properly labelling the trays to aid in their examination. For this, 

 as well as aid in cataloguing the collection, the Conservator is 

 much indebted to Mr. J. A. G. Rehn. 



Several valuable additions have been made to the collection of 

 birds during the year, notably the beautiful series of specimens 

 from Sumatra, collected and presented by Mr. Alfred C. Harri- 

 son, Jr., and Dr. H. M. Hiller, containing many forms new to 

 the collection. 



A collection of the birds of the Galapagos Islands was pur- 

 chased through subscriptions by members of the Academy. This 

 material fills an- important gap in our collection, as the Academy 

 previously possessed no specimens from this region. An interesting 

 series of New Mexican birds was collected by Mr. Rehn while on 

 the expedition sent out by the Academy in the spring, and many 

 other specimens were received through gift or purchase. 



The Delaware Valley Ornithological Club and the Pennsylvania 

 Audubon Society have continued to hold their meetings in the 

 Academy, and have done much to stimulate ornithological study. 

 By invitation the American Ornithologists' Union has arranged to 

 hold its twenty-first Congress at the Academy in November, 1903. 



Many visiting ornithologists have made use of the collections 

 during the year, and considerable aid has been given to workers in 

 other institutions.
