Anculotus flammatus. Lea, Reeve, Monog. Anculotus, t. 3, f. 18. 

 LejHoxis flammaUi, Lea, BiNNEY, Check List, No. 357. Conrad, ADAMS, Genera, i, 

 p. 307. 



Description. — Shell oval; spire short, convex; apex eroded; body- 

 whorl slightly compressed in the middle; epidermis horn-colored, 

 ri<^. 829. Fig. 830. With numerous series of small, angular spots; 

 ^\\ spots distinct within the labrum ; aperture obo- 

 W'C' ^ v^t<^) base regularly rounded. 



Habitat, — Inhabits pebbles on the bars in the 

 Alabama River, near Claiborne. 

 Length, flve-eigliths of an inch. — Conrad. 



Mr. Conrad's description applies only to a stunted or im- 

 mature form of this species, which grows considerably^ larger 

 and assumes some variety in marking. Mr. Lea's descriptions 

 of A. Foremaiii and A.Jlammata are subjoined. 



Anculosa Foremani. — Shell smooth, ovately gibbous, thick, yellow, 

 transversely lined; spire very short; sutures impressed; whoi'ls 

 somewhat flattened ; columella very thick ; aperture rather large, el- 

 liptical, whitish. 



Habitat. — Alabama. 



Diameter, -40; length, -50 of an inch. 



Observations. — Two of the three specimens under examination 

 have very distinct, capillary, revolving, deep brown lines between 

 the top of the aperture and the base. Above that the pjo-. gsL 

 space is nearly tilled up with two indistinct, interrupted 

 lines which give a clouded appearance to that portion of 

 the shell. The third specimen is of a brighter yellow, 

 with all the lines nearly obliterated. In form this species 

 very closely resembles A. flammata herein described, but 

 the capillary lines distinguish it at once, and the columella is thicker 

 at the base. In all the three specimens a slight tinge of brown may 

 be distinguished on the middle of the columella. I ( edicate the 

 species to Dr. Foreman, who kindly placed a specimen in my cab- 

 inet. — Lea. 



Anculosa flammata. — Shell smooth, ovately gibbous, thick, yel- 

 lowish, obliquely flammulate; spire very short; sutures impressed; 

 whorls somewhat flattened; columella very thick rbove; aperture 

 rather large, elliptical, whitish. 



Habitat. — Alabama.
