These pages, being written not so much for the use of those 
who are, but rather for those who desire to become, concho- 
logists,^"’ give descriptions of all North American species '^as 
concise and as free from technical words as possible.^^ All are 
figured: whenever good specimens could not be readily ob- 
tained for figuring, recourse has been had to previously published 
figures.^^ The parts published contain the genera Glandinay . 
Succineaj Vitrina, and all the genera or subgenera included by 
Lamarck and Pfeiffer under the name Helixy with exception of 
the Mesodontina. Hyalina cellaria, [Helix] Hygromia rufescen$ 
and hispida, Tachea hortensisy and Pomatia aspersa are enume- 
rated by Tryon as European species introduced into several 
localities in North America. Neitlier Vitrina limpida and 
Conulu^ chersina nor any species of Succinea is admitted to be 
identical with European species.
