30 MUSEUM OF COMPARATIVE ZOOLOGY. [Jan. 



this source of increase we are confident we must mainly rely 

 in future years, and our large stock of desirable duplicates, 

 numbering nearly 200,000 specimens, will supply the means for 

 extensive exchanges for a long period. 



Our receipts by donation have been smaller than usual, and 

 were derived from five persons only, as follows : — 



Jonathan Russell, 280 species, 1,396 specimens; 

 Lieut. David Mack, 52 species, 1,015 specimens ; 

 H. Higginson, 4 species, 472 specimens; 

 Dr. Molcher, 4 species, 8 specimens ; 

 Hugh Cuming, 32 species, 110 specimens; 



in all 372 species and 3,001 specimens only. Many of these 

 were, however, of rare beauty and value, and our thanks are 

 due to all for their generous kindness. 



Mr. Russell's donation may be mentioned as not only large, 

 but the specimens were also of uncommon beauty and very 

 perfect. The death of Mr. Cuming, whose collection stands 

 unrivalled for its extent and perfection, prevented a larger 

 contribution to our Museum. The few species laid aside for 

 us were kindly forwarded by his executors, and proved a highly 

 valuable accession. 



By the Gray Fund we have only added 39 species, 903 

 specimens, which were received from Japan. 



Our aggregate receipts during the past year through the 

 ordinary channels of exchange with twenty-four individuals 

 and institutions will, therefore, appear to be 2,444 species and 

 77,948 specimens ; but in addition thereto we can now state 

 that since our last report, Mr. Anthony's collection, then in 

 process of preparation for being delivered to the Museum, has 

 been completed, and the number of species ascertained to be 

 5,153, while the specimens number 101,309, a more minute 

 account of which may be found in the book prepared for the 

 purpose, in which every species is registered and the number of 

 specimens of each stated. 



Our consignments have been more numerous than usual 

 during the past year, forty-nine packages having been sent 

 away to thirty-three individuals and institutions, containing 

 4,787 species and 12,905 specimens, being nearly treble our last 

 year's work in this line.
