NO. 2 NEW TURRITID MOLLUSKS BARTSCH II 



slender, closely spaced, axial riblets, which are retractively slanting 

 posterior to the strong keel and protractive anterior to it. The base 

 is moderately short, well rounded, and marked by four strong spiral 

 cords, which are almost equally spaced, and by the continuations of 

 the axial riblets. A slender thread occurs between the third and 

 fourth. The columella is long and slender and marked by rather 

 regularly spaced spiral threads, which extend to the very tip and which 

 grow gradually weaker from the base anteriorly. The axial sculpture 

 on the base is almost as strong as on the spire, while on the colu- 

 mella it becomes decidedly weakened and evanescent toward the tip. 

 Aperture narrow, slender, with a deep narrow sinus on the outer lip 

 corresponding to the second keel. The rest of the outer lip is rendered 

 more or less sinuous by the external sculpture. The inner lip is ap- 

 pressed to the columella as a callus, and this callus extends over the 

 parietal wall.
