GONIOBASIS. 319 



Habitat. — Alabama. 



Observations. — A flue, show^', robust species, of a dark yellow 

 color, enlivened by several dark brown bands, generally two on each 

 whorl ; body-whorl angulated, with one band directly upon ripf. G15. 

 the shai'p angle, another in close pi-oximity, and a third 

 quite distant and near the base of the shell. Band obso- 

 lete on the first two or three whorls. Surface coarsely 

 striate and obscurely i-ibbed. — Anthony. 



This species appears to vary somewhat in form, 

 being onl}^ occasionally angulated at the periphery, but the 

 specimens are all covered with alternate, transverse, rounded 

 ribs and sulcations with a few nodules on the former.

Description. — Shell striate, conical, rather thick, horn-color; spire 

 rather elevated ; sutures rather impressed ; whorls somewhat convex ; 

 Fig. 610. aperture small, elliptical, angular at the base, within whitish. 

 Habitat. — Tuscaloosa, Alabama. 

 Diameter, -42; length, -8 of an inch. 



Observations.— 1 am not able to place this with any of the 

 ' species submitted to me by Dr. Budd, and although a single 

 specimen only is under examination, I have considered it 

 new. It has some resemblance to M. Ilaysiana, but is not so cylin- 

 drical, and the aperture is not so narrow. It is transversely striate 

 over the whole whorls. The length of the aperture is about two- 

 fifths the length of the shell. The aperture being eroded the number 

 of whorls cannot be ascertained. — Lea. 



The following description represents the young of this spc- 



Melania textilosa. — Shell conical, thick ; color uniform, pale green- 

 Ish-ycUow; spire not acutely elevated; wliorls 7-8, nearly flat, ob- 

 scurely striate and subnodulous ; body- whorl coarsely, but not thickly,
