and interesting display, while it will also increase faster 

 through exciting more public interest. The Curators' re- 

 ports show that there have been large accessions both in 

 Zoology and Botany during 1889, with some increase also 

 in the other departments. The want of means for working 

 at specimens and for making exchanges of duplicates with 

 other institutions has always been a drawback to the proper 

 development of the Museum, and cannot be remedied until 

 the new building is occupied. The collections on hand 

 continue to be as carefully preserved as circumstances will 

 permit, but want of room allows of the exhibition of only a 

 part of them. Considering that most of the Curators have 

 worked without compensation until within a few years past, 

 the condition of the Museum is highly encouraging.

 reports are classified as follows : 



Anthony J A. W., San Diego, Cal. : 2 living specimens of 

 Xerohates agassizii.
