B. EXAMINATION OF FISH FROM GREEN AND 
CRANBERRY LAKES. 
Fishes from two localities other than Oneida Lake have 
been available for study, Green Lake, east of Jamesville, on 
the Clark Reservation, and Cranberry Lake, Barber Point, 
Wanakena, in the Adirondacks. 
1. Green Laxn, East or Jamesvitie, N.Y. 
Green Lake. is interesting because of its geological history. 
It hes in a plunge basin formed at the time of the retreat of 
the great continental glacier, when an ice drainage stream 
plunged over the rocky walls, forming a river comparable to 
that of the present Niagara. The geological features of this 
region are well described and figured by Fairchild (1899, p. 
60; 1909, p. 31). The lake is situated southeast of Syracuse 
near Jamesville, covers an area at low water (summer) of 
3.3 acres and has a maximum depth of 62 feet. W. J. 
Endersbee and R. D. Adolph of the State College of Forestry 
have s‘udied the hydrography and the fish fauna. The fol- 
lowing mollusks were no‘ed during a short visit early in 
July, 1915: 
Planorbis campanulatus. Physa heterostropha. 
Planorbis antrosus. Physa@ gyrina. 
Galba obrussa exigua. Valvata tricarinata confusa. 
In a small pool at the subterranean outlet, which is a small 
stream, two species were noted, Physa gyrina, abundant, and 
Physa heterostropha, one specimen. On the hills surround- 
ing the lake seven land snails were collected. 
Polygyra albolaris. Pyramidula alternata. 
Polygyra thyroides. Omphalina fuliginosa. 
Polygyra tridentata. Omphalina imornata. 
Polygyra sayana, 
These species represent but a small fraction of the total 
number that undoubtedly inhabit this region. The hills 
about Syracuse seem especially favorable for the develop- 
ment of a large and varied land-snail fauna.
