Many'specimens have been added since the commencement of 

 his Curatorship, of species both native and foreign, by the dona- 

 tion of Sir William Jardine, Drs. Cragin, Burnett, Durkee, and 

 Storer, Messrs. Stimpson, Browne, Habersham, and Gary, and 

 of the Curator himself. 



A note was read from the Curator of Mineralogy ex- 

 pressing regret that he had not been able to prepare his 

 Report in time for the meeting, and promising it on some 

 future day. He concluded by tendering his resignation, if 

 any member were willing to take his place, and promising 

 another donation to the Society. 



The Curator of the Collections of Crustacea and Radiata 

 reported as follows : — When the department of Crustacea and 

 Radiata was intrusted to me, a few months since, my first care 

 was to put the whole, if possible, in a safe condition. By the 

 attacks of insects almost all the specimens of Crustacea had been 

 mutilated, limbs being detached, and in some cases lost, and of 

 some very valuable species so few traces remained that scarcely 

 any thing more was indicated than their former presence. 

 Among the Radiata, owing to the nature of the specimens, the 

 destruction was less, though the soft parts had been as completely 

 consumed. To prevent further injury, all with which the course 

 was practicable have been thoroughly saturated with corrosive 

 sublimate in alcohol. This process will probably need repetition, 

 especially with the larger specimens. 



Of the sources from which the principal portions of the collec- 

 tion have been derived, I can obtain no information. A very 

 valuable series of the Crustacea appear to have been brought 

 from Florida by Mr. Bartlett, but beyond those the indications 

 are very few. 



Of Crustacea, we have sixty-six genera, comprising eighty- 

 four species ; of Radiata, twenty-two genera, comprising thirty- 

 one species. Labels have been attached so far as time would 

 allow ; the remainder will soon be supplied. 



The Librarian offered the following as his Eighteenth Annual
