now in our collection. A full report on this collection is deferred 
until the whole has been properly catalogued and numbered. The 
shelves and specimens in Room K, containing most of the shells, 
and those in the gallery adjoining, have been dusted and placed in 
as good order as practicable, but this labor is really thrown away 
as long as the old cases remain in their present condition, with 
loosely fitting doors. 
Miss Bryant has looked over our special collection of New Eng¬ 
land shells and made a list of the species needed to fill gaps in this 
series, and has filled a few of these gaps with shells found elsewhere 
in the Museum. 
The Curator has continued his work upon the Achatinellidae, 
especially the ground shells of this family, and has practically 
completed the detailed descriptions in manuscript of all the species 
of the genera of this division throughout the whole chain of the 
Hawaiian Islands. In pursuance of the plan of this work, applica¬ 
tion has been made for the collections of these ground shells stored 
in the principal museums of this country. This part of the work 
has so far included only the small collections of the Yale University 
Museum and the Smithsonian Institution; but, as it has been going 
on for a short time only, and the progress has been rapid, it is 
thought that it will not take many months. The Curator will 
undoubtedly be able to enrich the collection by exchanges, and he 
has already found some exceedingly rare shells and some distinctly 
new species in the two collections so far studied. 
Rev. H. W. Peck has very generously placed his collection of 
Achatinellidae as a loan in the Society’s Building, and his Amastras 
and other land shells have been named and described. Mr. Oleson 
has withdrawn his collection of Achatinellidae, to offer them for 
sale elsewhere. There still remain in the neighborhood of 40,000 
shells in this building, and nearly a complete set of all the species 
of this family; so there is sufficient material. Special observations 
had also been made upon all of the Oleson shells, and the only 
loss is in the ability to revise manuscript relating to these from time 
to time, an omission which will tell more decidedly upon the value 
of Mr. Oleson’s collection than upon the memoir in which they are 
mentioned.

Professor Kingsley has completed the naming of fifty-three lots 
of the Ampliipoda loaned to him some years since, and these have
