were engaged. Very instructive materials have already been 

 accumulated, much of which can be placed on exhibition at 

 once. 



The materials of the Museum have been, as usual, freely 

 placed at the disposal of original investigators. The results 

 have either been published in the Museum publications or in 

 other scientific series. Prof. Smitt, of Stockholm, has com- 

 pleted his descriptions of the Florida Deep-sea Bryozoa, and 

 published the results in the Memoirs of the Stockholm Acad- 

 emy. Prof. Allman and Prof. Ehlers have both nearly finished 

 their reports on the hydroids and annelids of the Florida 

 Channel for the Museum publications. To Prof. Kolliker 

 considerable material has been sent for his monograph on the 

 Halcyonarians. 



In the entomological department Messrs. Cresson, Uhler, 

 Professors Frey, Zeller and Dr. Hagen have received assist-

 papers. 



The Museum publications have been kept up with increased 

 activity. In the Bulletin, short papers have been printed 

 during the past year by Professors Allman, Hyatt, Messrs. 

 Allen and A. Agassiz. To Mr. W. G. Binney the Museum is 

 indebted for the plate illustrating his communication. 



Mr. A. Agassiz has published for the Museum, Parts I. to 

 III. of the Illustrated Catalogue, containing a revision of the 

 echini. 



Mr. Bicknell has been mainly engaged in making sections 

 of crinoids, corals and mollusca. 



Messrs. Rcetter and Konopicky have been engaged in mak- 

 ing illustrations to accompany forthcoming publications of 

 the Museum. 



In accordance with the wishes of Prof. Agassiz, a part of 

 his library (3,000 volumes) has been presented to the Museum 

 Library. The remaining seven hundred volumes retained by 

 Mr. A. Agassiz have, together with his own library of about 

 twenty-five hundred volumes, been deposited in the Museum 

 Building. These important additions, with the books pre- 

 sented, from time to time, by Prof. Agassiz, will form, with 

 the existing library, an important nucleus for an excellent
