1893 .] NATURAL, SCIENCES OF PHILADELPHIA. 
REPORT OF THE PROFESSOR OF ETHNOLOGY AND 
ARCHAEOLOGY. 
I have to report that during the early months of 1893 a series ot 
free lectures was delivered by me on ethnology, in the lecture room 
of the Academy. They were well attended, and a commendable 
degree of interest was excited among those who were present. 
Suggestions have been made looking toward class instruction in this 
branch when suitable accommodation will be ready in the new build¬ 
ing. The subject of physical anthropology, a branch particularly 
germane to the purpose and collections of the Academy, has attracted 
considerable attention, and it is possible that a Section may be formed 
among the members for its special study. 
I have the honor to remain, 
Very respectfully, 
D. G. Brinton, M. D., 
Professor of Ethnology and Archaeology. 
REPORT OF THE PROFESSOR OF LOWER INVER- 
TEBRATA. 
The Professor of Lower Invertebrata respectfully reports that 
during the past year he has delivered twelve lectures upon zoological 
subjects. 
The additions to the museum during the year have been neither 
numerous nor important. 
Work has been carried on in the Carcinological department in re¬ 
labeling and rearranging the specimens. A catalogue of the Stoma- 
topoda, Caridea and Penseidea, including forty genera and one 
hundred and twenty-eight species, has been published in the Pro¬ 
ceedings for this year (see pages 194 to 227), and it is hoped that the 
second part of the catalogue, finishing the Decapoda will soon be 
ready for the printer. 
During a leave of absence on a trip to the Hawaiian Islands, 
although for Ethnological purposes, a number of invertebrata 
were collected which have not yet been studied. 
Respectfully submitted, 
Benj. Sharp. 
Professor of Lower Invertebrata.
