SCHIZOSTOMA. 367 



S. ornata, Anthonj-, is evident!}^ the young of this species. 

 I give the original description, and also a figure from the type 

 specimen. 



Melatoma ornatiim. — Shell ovate, somewhat pyramidally tiuTeted, 

 yellowish-olive, neatly, spirally corded with dark green ; whorls 5-6, 

 eoncavely sloping round the upper part, keeled at the Fig. 09l. 

 sutures; aperture small; fissure broad, moderately deep; 

 columella thinly inflected, pinkish-white. 



Habitat. — North Carolina, United States. 



Observations. — A charming little species, banded in a 

 most characteristic manner, with raised, dark green, cord-like ridges 

 upon a clear, yellowish-olive ground. — lieeve. 



Mr. Anthony's label is marked " Proc. A. N. S, Phil.," but 

 he never published the species. Mr. Reeve, misled by this 

 reference, has quoted Anculosa ornata, Anthony, as being the 

 description referred to, and consequently assigns North Caro- 

 lina as the habitat. It is scarcely necessary to repeat that 

 no species of Schizostovia has ever been positively ascertained 

 to exist in any other waters than those of the Coosa. I think 

 it very probable that pagoda, ivjramidatum and Wetumpkaense 

 are identical, but I have not sufficient data to ascertain the 

 fact positively.
