Distinguished from S. thompsoni by the finely wrinkled, not pitted, 

 apical whorls, shorter aperture and straight or convex columella. 

 According to Hidalgo the specimens figured by Philippi and Reeve 

 (which agree with those before me) are not fully mature ; the adult 

 having no notch or truncation at foot of columella. I have copied 

 on pi. 26, fies. 81, 83, his illustrations of the adult condition. S. 

 hartwegi differs from S. achilles in lacking spiral impressed lines.

Shell imperforate, oblong, solid ; irregularly striated and closely

 obtuse; suture submarginated. Whorls 5-1, slightly convex, the 

 last a little shorter than the spire. 



Columella arcuate, somewhat folded above, pale orange colored. 

 Aperture oblique, oval ; peristome unexpanded, thickened. Alt. 

 71, diam. 34 ; aperture alt. inside 35, width in the middle, 17 mill.
