Helix suppressa. Say, Des. ter. and fluv. shells, p. 14. 
Description. Shell small, subglobose, depressed, polished, somewhat pellucid. Volutions 
six in number, wrinkled. Spire convex. Aperture sublunate, narrower beneath. A single 
prominent tooth within, near the base and distant from the margin. — Pillar-lip smooth, simple. 
Umbilicus small and deep; the umbilical region indented. 
Color. Pale horn; the body-whorl opake ; whitish near the aperture. 
Diameter, 0° 2. 
This species occurs throughout New-York and Pennsylvania. It has the habit of H. ligera, 
except in size and armature. It is also frequently confounded with H. gularis, which it 
resembles very much both in size and external characters. It differs, however, in its armature.

PLATE Ill. FIG. 29. —(STATE COLLECTION.) 
Description. Shell moderately large, orbicular, subconic, thin. Apex elevated. Lip simple. 
Umbilicus narrow, but open to the apex, the basal margin being folded over so as to cover 
partially the entrance. Volutions five, subrounded, rather’ flattened ; apicial whorl smooth ; 
all the others with numerous equidistant stric, which are also impressed on the interior. 
Body-whorl obtusely carinate in the upper third of its centre, near the junction of the outer 
lip, but becoming effaced and almost obsolete on the margin of the outer lip. Suture deeply 
impressed. 
Color. Chesnut-brown externally, purplish within; a light colored revolving line on the 
upper third of the body-whorl, and is lost in the suture. 
Diameter, 0°4. Height, 0°31. 
This species I derived from Dr. Newcomb, who obtained it from Manchester, Ontario 
county, and also from moist woody places in Wayne county. It was labelled “intertezta, 
Gould ;” which name I have retained. It appears to be a very distinct species, although from 
its markings it may prove to be the young of H. solitaria; but that species has a wide 
umbilicus. It is allied in the form and covering of the umbilicus to H. znornata, but differs 
in the angle of the outer lip with the body-whorl.
