our shell to be a distinct species from that which is found iu 

 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 arc 

 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 5 whorls five, regularly rounded, and with obso- 

 lete and irregular wrinkles across them ; beneath whitish ; umbi- 

 licus moderate, not exhibiting the volutions. PI. 1, Fig. 3. 

 Taken by Mr. Gr. 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 niiens 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. i. 



Helix thyroidus. Polygyra auriculata. 



" minuta. " avara. 



" labyrinthica. " septemvolva. 



" hirsuta. Oligyra orbiculata. 



" perspectiva. Succinea campestris. 



" lineata. " ovalis. 



Polyphemus glans. 



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.

 sembles Turbe rmiscorum of authors.
