Spurious Species 

 Anculosa pumilus Conrad, New Fresh Water Shells of U. S., p. 62, 1834. 

 This is a Somatogyrus. 

 Anculosa flammata Lea, Proc. Anier. Phil. Soc, II, p. 243, December, 1843. 



Description was from a single specimen and was based principally upon a 

 pathological condition in which the coloring matter of bands or lines is 

 deposited longitudinally. Frequently a shell of this kind has bands or lines 

 as well. Several species in the Alabama collection have occasional flammata 

 specimens. They are most common in the picta group and it is to this group 

 that Lea's species appears to belong, though just to which one it cannot 

 here be said. 



Anculosa incisa Lea, Proc. Amer. Phil. Soc, II, p. 243, 1843. 

 This is Gyrotoma incisa Lea. 



Anculosa solida Lea, Proc. Amer. Phil. Soc, II, p. 243, 1843. 



According to Tryon this equals Lithasia hnnns Lea, described at the same 

 time. 



Anculosa squalida Lea, Proc Amer. Phil. Soc, IV, p. 167, 1845. 



Nothing among Mr. Smith's collections corresponds to the Lea descript- 

 ion and Tryon's figure with exactness, and Mr. Smith himself does not 

 appear to recognize it. The type locality is Tuscaloosa, which is on the 

 Black Warrior. The only Anculosa of the size of squalida which is known 

 from that stream is plicata, described by Conrad in 1834. Lea's figure and 

 Tryon's are of quite different shells and, seemingly, different genera. 



Auculosa contorta Lea, Proc. Acad. Nat. Sci., Phila., XII,' p. 187, i860. 



No material which can be ascribed to this species appears in the Alabama 

 collection. It was described from one specimen, taken by Dr. Schowalter. 

 It is in all likihood a deformed individual. 



Anculosa planulata Lea, Wheatley Cat. Shells, p. 28, Alabama; description not 

 published. 



Tryon seems to think this equals A. aiiipla Anth. 



A mollusk named by Anthony Mclatoma- sphaericum (Reeve Monog., 

 sp. 8, 1861) and recognized by Tryon as a Schizostoma (Gyrotoma) is evi- 

 dently an Anculosa, probably belonging to a described species of the picta 

 group.
