but indented in the umbilical region^ spire sliglitly convex; wliorls 

 5J, rather flat, last one suddenly but slightly deflected ; aperture very 

 oblique, transverse, ear- shaped, narrowed by a rather slender, tongue- 

 shaped tooth, which extends nearly across the whole width of the ap- 

 erture ; peristome callous, margins slightly but distinctly reflected and 

 thickened within; basal margin slightly arcuate, but entire; with an 

 internal transverse tubercle at the base of the shell. Great''.r diameter

Stenotrema harhigera, Tryon, Am. Journ. CoDch., iii, GO (1667). — W, G. Binney, Terr. 

 Moll., V, 294. 



A species of the Cumberland Subregion, ranging into North Caro- 

 lina, Georgia (Habersham County), and Alabama. 



Smaller and more delicate ihnw S. spinosum ; striiie more numerous, 

 thickly set with fine cilia, which project at the periphery in a fine 

 fringe, and not like short, triangular aculei, as in spinosum. The um- 

 bilical region is less depressed, the parietal tooth much more delicate, 

 and does not overlap the peristome, which stands off from the shell 

 and is not appressed to it. S. Udgarianum is much more solid and ele- 

 vated, has the parietal tooth more developed, the peristome notched, 

 as in S. Jiirsutum, but has about the same diameter. 



Jaw as usual, with 12 crowded ribs. 



Lingual membrane (Terr. Moll., Y, Plate YII, Fig. C) has 21-1-21 

 teeth ; 8 perfect laterals ; but even the third has its inner cutting point 

 greatly produced. 



Genitalia as in 8. stenotremum. 



Stenotrema steiiotreiiiuin, Fer. 



Shell imperforate, globose, diaphanous, reddish, hirsute, convex 

 above, inflated below; spire elevated; whorls 5, somewhat fig. 294.* 

 convex, the last anteriorl}" gibbous, angularly deflected ; aper- ^^^^ 

 ture irregularly transversely lunar, almost linear, contracted 

 by a long, stout, elevated lamelliform tooth along the whole ^-:*0) 

 length of the i)arietal wall, furnished far within, on the base of \^^ 

 the last whorl, with a transverse tubercle, springing from the ^'Tmm!^ 

 axis; peristome scarcely expanded above, thickened by a heavy, regu- 



* The figure does not show the hirsute character of the shell.
