GONIOBASIS. 169 



tened, with numerous folds; body-whorl slightly convex, suture 

 impressed; aperture pyriform, purple, obtusely rounded before, 

 five-eighths of an inch. 



Habitat. — Tennessee ; Mr. Anthony. 



Observations. — Bears some resemblance to M. decora, Lea. I for- 

 merly proposed the name .substricta for M. conica, Say, supposing the 

 name to have been previously applied to the 31. conica, Gray. A sub- 

 sequent examination of the dates has satisfied me that Say's name 

 has priorit}-, so that Mr. Gray's species now requires a new name, 

 unless the citation of the author presents a sufficient distinction. —

Description. — Shell folded, subfusiform, thick, pale chestnut-color, 

 without bands; spire obtusely conical; sutures irregularly impressed; 

 whorls about six, somewhat convex; striate at the apex; aperture 

 large, ovately rhomboidal, whitish within ; outer lip acute, slightly 

 sinuous; columella thickened, incurved and twisted. 



Operculum ovate, thin, light brown, with the polar point on the 

 left margin near the base. 



Habitat. — North Alabama; Prof. Tuomey. 

 ; Diameter, -29 ; length, -70 of an inch. 



Observations. — A number of these species were sent to me by the 



late Prof. Tuomey, but the older ones are very imperfect,

being generally decollate. Most of them are young. The 



largest is nine-tenths of an inch long, but it is too imperfect 



to figure. The folds are close, regular and are oblique to the 



right. On the upper whorls there are one or two stri;c 



which cut the folds as in Melania (Goniobasis) Deshaycsiana 



(nobis). The apei-ture is nearly half the length of the shell. — Lea.
