which is spolteil rather than banded.

 Columbella vabia. Col. testa oblongd, decuisato-costatd, 

 apice acuminata, anfractibus octo ad novem, castaneis

 Hab. Panama (under stones); Cuming. 



The sculpture of flexuous ribs which encircle this spe- 

 cies is similar in character to that of C. scalarina. The 

 shell is of a more acuminately oval form.
