GOXIOBASIS. 807 



Observations. — This is an obscure species and is near to crepera 

 herein described, but it is more inflated, and reminds one of bulhila 

 also herein described. But it has not the well marked bands of that 

 species, some individuals being without any bands, while others have 

 a few very obscure ones. In some there are very obscure striae 

 towards the base of the lower whor-l. All the specimens before me 

 being worn at the tips, I cannot make out the character of the apical 

 whorls. The aperture is about one-third the length of the shell. — Lea. 



Very closely allied to G. solida.

Description. — Shell substriatc, conical, somewhat thick, dark brown; 

 spire somewhat elevated ; sutures impressed ; whorls about six, flat-

Habitat. — Yellowleaf Creek, Alabama; Dr. E. 11. Showalter. 



Diameter, '37; length, -oi of an inch. 



Observations. — This is a modest looking species near to 

 pudica lierein described. One of the specimens has a few obscure, 

 transverse stria; on the lower part of the whorls, the other has them 

 nearly over the whole surface. Both specimens are imperfect at the 

 spire. The aperture is about one-third the length of the shell. — Lea. 



Dili'ers from the previous species of this group iu the form 

 of the aperture.
