GONIOBASIS. 167 



Description. — Shell striate, acutely conical, rather thin, cinnamon- 

 brown; spire elevated, somewhat attenuate, at the apex cariuate and 

 granulate; sutures impressed; whorls seven, convex; aperture small, 



elliptical, anj^ular at the base, reddish Avithin; columella 



rig.322. 

 smooth. 



Habitat. — Coosa River, Alabama: Iluntsville, Tennessee. 



Diameter, "28 ; length, -83 of an inch. 



Observations. — Among the numerous Mdanice sent to me 

 long since by my late friend, Prof. Troost, were several speci- 

 mens of the young of this species. I could not satisfactorily 

 place them in anj^ known species, and I put them temporarily with 

 striatula (nobis), which is strongly allied to the species which I 

 have described above. Eecently, I have received from Prof. Brumby 

 and from Mr. J. Clark several adult specimens, which leave the 

 younger in my possession no longer in doubt ; they were recognized at 

 once to belong to those more recently received. All the specimens 

 before me, some dozen, are reddish ; the striatula is horn-colored, 

 with a white aperture. The latter is also flatter in the whorls, and 

 not so cai'inate above, nor are the sutures so deeply impressed. Some 

 of the specimens are quite smooth on the body-whorl. Aperture 

 about one-third the length of the shell. — Lea.

ture large, elliptical, bluish. 



Habitat. — Georgia; Major Le Conte. 

 Diameter, -35 ; length, -80 of an inch. 

 Observations.— The folds of thi.s species extend over the 

 whole shell, except the inferior half of the body- whorl. The 

 aperture is large, and somewhat dilated, being nearly one- 

 half the length of the shell. I owe the possession of sevei-al speci- 

 mens to the kindness of Major Le Conte, to whom I dedicate it. — Lea.
