* Never published by Mr. Anthony, who sent a specimen with label attached, marked ''Proc. 

 A. N. S.," to Mr. Reeve. Mr. Reeve, misled by this reference, refers in his description to Anc. 

 i,rnata, Anthony, and consequently assigns North Carolina as the habitat. No sppcies of Schizos- 

 toma is known to exist out of Coosa River, Alabama. S. ornata is the young of Wetumpkaense.. 



fMr. Reeve's figure 20. intended for this species, I refer to S. babylonicum, Lea. Alabamense is 

 distinguished from labylonicum, by the regularity of its striae. 



IMr. Reeve's figure (3) of this speecies is a Goniobasis lieta, Jay. 



2) This figure does not so well represent funiculalum as fig. 1, b, intended for S. pagoda. 



f Mr. Lea, (Jour. Acad. Nat. Sci., y. pt. 3), makes this species to equal his S. constrictum. I do 

 not consider them the same; constrictum is longer anil narrower. 



If Mr. Reeve's figure 7, a, represents rather a smooth variety of salebrosum, Anth. 



**In a large number of specimens before me, the distinctive features of salebrosum and robustum 

 become so completely and insensibly merged together that I cannot separate them, and believe 

 them to be identical.
