170 SEMINELLA. 



(figs. 14-17). The figures have no size-mark attached, yet there 

 can be little doubt that they are greatly magnified ; they include 

 shells more varied in color than anything we have been accus- 

 tomed to refer to C. atrata, yet among them is one that is per- 

 fectly and others that are nearly typical in this respect.
