of an inch. This little species, first described by the 
writer from specimens found in Maine, has since been 
discovered in Massachusetts, and two specimens have re- 
cently been received from California, one from San Fran- 
cisco, and the other from the Sierra Nevadas, showing an 
unusually wide distribution. 
Hewtx Ferrea Morse (Fig. 37) is slightly larger than 
seh H. milium, and has a steel-gray tinge,

LA has been found in Maine, Massachusetts, 
and New York. 
Herrx cnersINa Say. (Fig. 38.) A very character- 
istie species. The shell is conical, thin, 
polished, amber-colored ; extremely fragile. 
Whorls five to six, rounded. Base convex; 
aperture narrow ; umbilicus absent. Diame- 
ter one-tenth of an inch. This species occurs 
in nearly all parts of the United States, and is quickly 
recognized by its turreted and fragile shell. 
The shells of the following group are not smooth and 
polished as in the majority of those just described, but 
many of them are coarsely striated, and a few have re- 
flected lips. They are all quite small, and variable in 
form, certain species having an elevated spire, while 
others are quite flattened. The denticles on the tongue 
are not claw-shaped as in those previously-deseribed, but 
are notched like a saw.* All the species are very charac- 
teristic, and easily recognized.
