ACHATINA.— Plate XIII. 
Glcmdina truncata, Say, Amer. Conch, pi. 20. 
II ah. Florida. 
This very interesting shell is, without doubt, the Glan- 
dina truncata of Say, according to his figure, but whether 
it is the original Bulla truncata of Gmelin, it is impossible 
to tell ; for Gmelin, like Say in the instance before us, may 
have confounded two or three species as synonyms under 
one specific name. A close examination of the characters 
of the shell under consideration, which, as being the 
species figured by Say, may as well have the name truncata 
assigned to it, will show that it is perfectly distinct. The 
rib-like stria; have a more elevated plicate structure, and 
they differ materially in having no indented punctures ; the 
colouring is also peculiar, the aperture being tinged with 
a rich flesh-pink.

Lea, Trans. Amer. Phil. Soc. (Extr.) p. 196, pi. 19. f. 78. 
Hab. Mexico. 
This species of Mr. Lea’s approaches very closely to 
that subsequently named A. Sotcerbyana, by Dr. Pfeiffer, 
represented at PI. VIII. The white flakes serve never- 
theless to distinguish it.
