Annual Keport.J 8 [May 7, 



has chiefly been occupied with the larger and more showy 

 genera, and has completed the Probosciclefera, the Toxifera 

 and a few families of the Rostrifers and Opisthobranchiates. 



As for the remaining invertebrates Mr. Emerton has 

 labelled over 2000 bottles of Crustacea, and also many New 

 England worms and radiates. He has mounted on plaster of 

 Paris or wooden stands many corals and sponges, and pre- 

 pared new labels for the former. 



Collections of marine invertebrates were made at East- 

 port last summer by Messrs. Emerton and Saltonstall, and 

 presented to the Society. 



No change has been made during the year in the collec- 

 tion of the Microscopical department. I would suggest that 

 as soon as possible a suitable person be employed to arrange 

 this large collection, and put it in available order for stu- 

 dents. 



The increasing duties of the members of the committee on 

 Comparative Anatomy have not allowed them to devote so 

 much time to their collection as in the last two years. The 

 "homological series," however, has been nearly completed, 

 and several dissections and wet preparations have been 

 added. The series of hearts is now in good condition. 



During the winter new locks have been put on the cases 

 in the two corner rooms, and the same should be done with 

 the cases around the main hall, as the present fastenings are 

 very inconvenient. It would be well, also, to introduce glass 

 partitions at suitable points in the cases, as a prevention 

 against dust.

Much work has been done during the year on the collec- 

 tion of fossils, which is now arranged in the best possible 

 manner, for exhibition and study. Few additions have been 

 made to the collection, a most valuable one, however, is a 

 trunk of a Sigillaria from the Joggins Mine, Nova Scotia, 

 presented by the Institute of Technology. The trunk is 

 about six feet in height, and will make a striking object
