Museum, and with considerable benefit to the Entomological 

 Department, notwithstanding the inconvenience caused by the 

 lack of sufficient accommodation for all the workers engaged. 



The number of specimens received from the Imperial Bureau 

 in the course of the year amounted to 64,736, or nearly half of 

 the total number acquired from all sources during the year. A 

 considerable proportion of the material had been named by the 

 staff of the Bureau, or by specialists outside, before presenta- 

 tion to the Museum, and included several types and other 

 specimens of more than ordinary value, in addition to a large 

 number belonging to species of economic importance.

 the year. 



As no change has been made in the general arrangements 

 with regard to the Library which were in force before Entomo- 

 logy became a distinct Department, other matters relating to 

 the Entomological Library may be looked for, under the above 

 heading, in the statement by the Keeper of Zoology.
