206 GIBBULA. 



quadrangular; columella oblique, straight, scarcely nodulose; uni- 

 bilcus narrow, funnel-shaped. (Phil.) 



The shell consists of 62 whorls, which are flat, scarcely separated 

 from each other ; they form an elevated cone with blunt apex, and 

 the last passes into the base in a sharp angle. The sculpture con- 

 sists of 6 to 9 uneven, elevated, smooth spiral lines on the upper 

 surface, and about 8 similar concentric lirre on the base. The um- 

 bilicus is pretty narrow, widening and funnel-shaped at the opening. 

 The color is just as in T. villicus. From this, its nearest ally, leuco- 

 phcKiis is separated by (1) its size; (2) its completely flat whorls; 

 (3) the numerous spiral lines ; (4) the narrower umbilicus.
