REPORT ON THE RADIATES. 
By J. WALTER FEWKES. 
THE most important addition to the collection of Radiates dur- 
ing the past year is a number of desirable specimens, mostly 
identified, from the Museum of the Peabody Academy at Salem. 
These are well preserved, and a valuable acquisition especially to 
our collection of Echinoderms. 
A set of all our deep-sea ocean deposits has been sent to the 
Rev. A. M. Norman. A few rare deep-sea Echinoidea were sent 
to Professor Duncan, and specimens of ocean bottoms have been

in the African Room, and a number of mounted Sponges added to 
those already on exhibition in the Systematic collection. 
Faunal representative genera of Molluscan shells, selected from 
the general collection by the late Professor Hamlin, have been 
mounted and placed on exhibition in the African and South 
American Rooms. 
The alcoholic Bryozoa, Tunicata, Pteropoda, and Heteropoda 
stored in the cellar have been assorted preparatory to a special 
study. 
During the year I gave a course of about thirty lectures on the 
Radiates of the New England coast. These lectures were attended 
by twelve persons, Scientific students, post-graduates, and others 
not members of the University. 
A special student worked in my room on Systematic Zodlogy 
six hours a week during the year. Several others took laboratory 
instruction. The work of two students in the Marine Laboratory 
at Newport during August and September was conducted under
