obtuso ; whorls five, rather convex; columella marked; outer lip 

 spread out.

Diameter, -4 ; length, -6 of an inch. 



Observations. — I am indebted to Mr. Nicklin for this new species, 

 it having been found by him in Indian Creek, between the ^ig. 778. 

 Salt and Red Sulphur Springs, The sinus is so small that 

 at first view it may easily escape observation. The aper- 

 ture is large, and in this it has some resemblance to a 

 Paludina. Near the base of the columella a purple spot 

 may be usually observed. It resembles most in outline the 31. tu- 

 herculata (nobis), but diflers in not being angulatcd, and in being 

 entirely without tubercles. lu color it diflers entirely. Some indi- 

 viduals have three colored purple bands in the interior, while others 

 are devoid of them. — Lea.

 called by Professor Haldeman variety striata; No. 780 he

 they have been so quoted since by

"Within a few days I have observed in the 

 Boston Journal of Natural History, vol. 3, No. 

 3, descriptions of two new species of Ancidosa 

 by Mr. Anthony, Anculotus carinatus and An- 

 ciilotus Jurtlandiamis, both from t! e Falls of the 

 Kanawha. Judging from the description and figures, I am led to the 

 conclusion, that both these are identical with 3L inflata, and from 

 the great variety of this protean species, I am not surprised at its 

 being mistaken. The peculiar character, however, of the angle and 

 channel of the base in this species, is evident throughout. I am not
