488 PROCEEDINGS OF THE ACADEMY OF [1890. 
science will have good results both generally and for this institution. 
A similar series, limiting the field to modern Europe, is in prepa¬ 
ration for the present winter. 
The collections in the departments of Archaeology and Ethnology 
are substantially in the same condition as at the date of my last 
annual report. Want of exhibition space has prevented any material 
increase in the number of specimens, and even the present collections 
are barely accessible to students. The construction of a new build¬ 
ing for the use of the Academy gives hope that before long a more 
satisfactory display of these collections will be possible. 
Respectfully submitted, 
D. G. Brinton. 
REPORT OF THE PROFESSOR OF INVERTEBRATE 
ZOOLOGY. 
The Professor of Invertebrate Zoology respectfully reports that 
ninety trays of marine, fresh-water and land shells, collected by 
him during the winter of 1888-89, on the Caribbean Islands, 
have been presented. 
During the past year he delivered seven lectures on the “ Carib¬ 
bean Islands,” five of which were illustrated with lantern slides. 
It is proposed to give a course of lectures on the “ Principles of 
Zoological Philosophy” during the spring of the coming year. 
The additions to the museum have been important. A small 
part of the collection made by the expedition of the Academy 
of Natural Sciences, under the charge of Professor Angelo Heil- 
prin, including Echinodermata and corals, have been presented. 
The bulk of the collection is now being worked up, and will be 
formally presented in the coming year. 
A collection of Echinoidea, Asteroidea, Ophiuroidea, Holotliuroi- 
dea, Crinoidea, Anthozoa, Hydroidea, Crustacea and Annelida, 
principally from the dredgings of the U. S. Fish Commission 
steamers, have been presented by the Smithsonian Institution. 
Respectfully submitted, 
Benjamin Sharp, 
Prof, of Invert. Zool.
