thing on Pelecypoda. A considerable number of fossil Gasteropoda 
have also been selected from the general collections, mounted, and 
placed on exhibition. Mrs. Sheldon has also described about fifty- 
eight species of Crustacea and selected and mounted a limited num¬ 
ber of specimens. 
Miss Martin has been as usual more or less occupied in making 
colored drawings for this collection, especially during the summer. 
The labeling of the tablets has been done by Miss Bryant and also 
the preparation of some of the fossils. 
Botany. 
Less work than in previous years has been done upon the herba¬ 
rium, owing in part to the unfortunate sickness of the assistant, 
Miss Carter. She nevertheless continued through a large part of 
the past official year the work upon the labeling of the Lowell col¬ 
lection and systematic arrangement of the duplicates and the poi¬ 
soning of the plants. During the summer she also looked over and 
cleaned the specimens on exhibition and placed in position a series 
of shelf labels indicating the different divisions of plants, and Miss 
Bryant assisted her by making these labels. Thirty species of North 
American lichens were added by purchase from Cummings, Seymour, 
and Earle. Nineteen persons have been permitted to consult and 
study in the herbarium. 
Palaeontology. 
Miss Bryant has this year worked upon the renovation of the 
tablets and specimens in the European room, especially in Oolite, 
and has rewritten about four hundred labels. She has also worked 
over all of the American Jurassic and Cretaceous fossils and has 
cleaned from the matrix and mounted a number of Silurian fossils 
of the American collection from Anticosti, and a collection of fos¬ 
sils from the St.John’s group has also been cleaned and mounted 
by the same assistant. A number of Devonian corals purchased 
from Mr. Greene have been identified and labeled, and the Vertebrata 
from the Cretaceous freshly labeled. The same assistant revised 
the work previously done by other assistants upon the Trenton and 
Niagara fossils and relabeled them. She also finished the Carboni¬ 
ferous fossils including the Brachiopoda, Lamellibranchiata, Gastero¬ 
poda, and Cephalopoda.
