mens of each species, so that a student wishing to identify an 

 unknown insect may glance quickly over many already named 

 species. It also becomes, by means of cross-reference labels,

 accessories and sketches for a number of habitat groups of 

 local butterflies. There are special difficulties in the way of 

 successful insect habitat groups, but we believe that these dif- 

 ficulties can be overcome, and if so the groups will be both 

 interesting and instructive. 



Professor Crampton has continued his researches for the 

 distribution and variation of Partula. Mr. Miner has made 

 progress with his "Synonymy of American Myri- 

 p e br irC ti and a P 0(is >" assisted by Miss Anita Ohrtmann. Dr. 

 Van Name has continued his investigations on 

 the "Ascidians of the West Indian Region," the results of 

 which are now in press. The following papers, published in 

 the Bulletin during 1920, indicate the scope of scientific re- 

 search in the Department.
