248 College of Forestry 
tion is by Rev. W. M. Beauchamp, of Syracuse, N. Y., who 
catalogued the Land and Fresh-water Shells of Onondaga 
County in 1886. 
Sixty-two species and varieties, 25 genera and 11 families 
are represented in the collection of fresh-water mollusks 
from Oneida Lake. No new species were observed, but 
six species are reported from the State for the first time — 
Lampsilis borealis, Pisidium henslowanum, Valvata bieari- 
nata normalis, Physa ancillaria warrencana, Planorbis bin- 
neyt, and Lymnea stagnalis lilliane. The peculiar Lymnzid, 
Acella haldemani is reported for the first time from this part 
of the State, as are also Spherium vermontanum, Musculium 
rosaceum, Pisidium compressum lavigatum, P. equilaterale, 
Vivipara contectoides, and Ancylus fuscus. Four species of 
Pisidum still remain to be determined. 
Compared with the total number of fresh-water mollusks 
found in the State, and in several State localities, the fauna 
of Oneida Lake presents a good showing. This comparison 
is shown in Table No. 17. Varieties are here treated as 
species and other lists have been reduced to the modern 
nomenclature.
