onr shell to be a distinct species from that which is found in 
France ; we therefore apply a new name. Found under bark of 
dead trees and in moist places, and is not uncommon. In the 
young shell the whorls are less rounded and flattened above, so as 
to form almost an angle with the exterior margin ; the colors are 
altogether paler, and may be described as pale yellow spotted or 
. above radiate with reddish brown, and a row of spots interrupted 
from the radii by the immaculate prominent margin. 
5. H. GLAPHYRA. — Shell very much depressed, thin, fragile, 
pellucid, polished ; whorls five, regularly rounded, and with obso- 
lete and irregular wrinkles across them ; beneath whitish ; umbi- 
licus moderate, not exhibiting the volutions. PL 1, Fig. 3. 
Taken by Mr. G. Ord in his garden in Philadelphia. 
This species and the preceding are referable to the genus Zoni- 
tis, Montf. — a name which is objectionable from its being used in 
Entomology. 
It considerably resembles Helix nitens of Europe, particularly 
in being whitish beneath, and will be properly arranged next that 
species in the systems. 
The following species of Helix and other genera were also de- 
scribed in this paper, but the descriptions and remarks are merely 
a repetition from the Journal of the Academy, vol. 1. 
Helix thyroidus. 
Polygyra auriculata. 
“ minuta. 
avara. 
“ labyrinthica. 
“ septemvolva. 
“ hirsuta. 
Oligyra orbiculata. 
“ perspectiva. 
Succinea campestris. 
lineata. 
“ ovalis. 
Polyphemus glan&. 
Pupa corticaria. — Shell dextral, cylindrical, obtuse at the 
apex ; whorls five, not precipitately wrinkled or striate ; aperture 
suborbicular, lip reflected ; a single tooth on the pillar-lip, near 
the outer angle ; inner angle with an angular projection resembling 
a second tooth, sometimes obsolete. 
Length about the tenth of an inch.

Very common under the bark of trees, near the earth, and re- 
sembles Turhe muscorum of authors.
