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 

 picked out for Mr. Murray. 



The Assistant has been consulted by several persons in regard 

 to the identification of specimens and comparison with types. In 

 one instance, he has identified for use in the school-room a collec-

A representative collection of Corals has been put on exhibition 

 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 Zoology 

 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
