49 Storer on the 
In the stomch of this specimen, taken in Muddy 
Pond, Roxbury, I found five specimens of the 
« Helix albolabris? with the contained animal; 
one only was perfect, the others being more or less 
digested ; this specimen measured one inch in its 
greatest diameter, and was five lines in height. 
This species usually feeds upon frogs and in- 
sects, and the farmers assert that it sometimes robs 
them of their chickens.

This species appears very early in the spring, and 
continues extensively distributed throughout the 
season. It may be at once recognised by its green- 
ish color, and yellow throat. Length of the speci- 
men before me, three inches ; length of the poste- 
rior extremities, four inches and a half. Head and 
upper part of the anterior portion of the body, of 
a brilliant green color; posterior portion of the 
body slightly maculated, greenish, mixed with 
brown ; sides granulated, brown ; mottled with irreg- 
ularly formed and distributed black blotches, beneath 
the throat, yellowish ; abdomen white. Head one 
ineh long; snout blunted and yellowish at the 
extremity. Eyes very prominent; pupils black; 
irides metallic, encircled by a brilliant golden ring. 
Nostrils nearer to the eyes than to the mouth.
