and has been occupied since almost exclusively in this department. 
The fossils of the American faunas on exhibition in Room G, except 
the New England collection contained in the central cases, and the 
Main Hall, and a large part of those of the European faunas of the 
Eser Collection have been removed, dusted, the shelving cleaned 
or repainted, and the specimens replaced. In order to carry on the 
work of revising the collection, it was necessary to get together all 
of the fossils that have accumulated in the past ten years. Part of 
this work had already been done, but Miss Bryant spent consider¬ 
able time in going over and cataloguing the fossils stored in the 
trays under the exhibition cases of the Main Hall and the European 
room and those in the basement. The revision and renaming of 
the collections on exhibition had become necessary, and this has 
been carried out through the Devonian, Subcarboniferous, and a 
large part of the Carboniferous. This part of the work included 
the dismounting of the specimens upon each tablet and the repaint¬ 
ing of the tablets in many cases as well as the writing of new labels. 
In making additions to the series of exhibited specimens from the 
new accessions, quite a large number of fossils had to be cleared 
of the rock in which they were more or less imbedded, especially 
among the Crinoidea, and this occupied considerable time. 
The series of Palaeozoic corals received last year from Mr. G. K. 
Greene has been catalogued and selections made for exhibition. 
We are indebted to Miss Isabel L. Johnson for the donation of 
a valuable series of sponges and other fossils from the Jura in the 
neighborhood of Oxford, England.

The Curator has reported in preceding years upon the Society’s 
collection of Achatinellae of the Hawaiian Islands, and his investi¬ 
gation of the laws that governed the evolution of this remarkable 
group. Although not consciously admitting the existence of the 
need of more materials in order to complete this work, he has 
really been gradually approaching a point beyond which progress 
could not be effectively made until more shells were obtained. 
This in brief has been effected after long negotiation by the 
purchase of the Rev. J. T. Gulick’s personal collection. This ac¬ 
cession makes the Society’s collection the most complete in exis-
