24 ANNUAL REPORT OF THE 



theses are given in the Contributions now in press. Dr. Ban- 

 croft has received an appointment to a Parker Fellowship, and 

 proposes to study abroad. The recently established degree of 

 Master of Science was conferred in June upon a student in 

 Zoology who was in attendance at the University in the Graduate 

 School during 1896-97, and the degree of A. M. upon six students 

 whose work was chiefly zoological. 



The more important of the Contributions from the Zoological 

 Laboratory during the past year have been published in the Museum 

 Bulletin as heretofore by the co-operation of the Curator and the 

 Corporation of Harvard College. The following is a list of the
