Two cotypes are figured, since Adams' description wa& 

 drawn fro'm several individuals. His measurements apply 

 to the largest example in the type lot (fig. 54), while the 

 coloration was described from the better colored smaller 

 shells. The specimens figured measure 



Length 13.1, diam. 3.1, aperture 4 mm., whorls 7%. 



Length 10, diam. 3 ,mm., whorls 6%. 



The first whorl is smooth. The striation is coarser than 

 in V. blandiana, and the striae are straighter. The streaks 

 are paler, often so pale that only the chestnut subsutural 

 spots are noticeable. The columella is nearly straight in an 

 oblique view in the aperture, and very obliquely excised 

 basally. 



The relations of this species to V. propinqua need further 

 investigation. They are very closely allied, and I doubt 

 whether a specific distinction should be maintained.

"Shell elongate, somewhat conic: horn color: with numer- 

 ous well impressed regular transverse striaa: apex subacute: 

 spire with the outlines a little convex: whorls seven and 

 one-half, scarcely convex, somewhat shouldered above, with 

 a well impressed suture; aperture ovate, acute above: la- 

 brum thin, slightly advanced in the upper half, retreating 

 below: columella. moderately curved, distinctly truncated. 

 Mean divergence about 14 ; length of spire .21 inch ; total 

 length .3 inch; breadth .075 inch." (Adams).
