ately rounded, the sutui-e distinct, not appressed; spiral sculpture of 

 (on the spire four, on the last whorl five) equal and equally spaced 

 rounded cords with more or less intercalary minute thi'eading, on the 

 early whorls; the anterior pair of cords are somewhat more ])rominent 

 than the others ; the base is disk-like, flattish, with six or more feeble 

 spiral threads between the carinate margin and the imperforate axis ; 

 axial sculptm-e of (on the |.>enultimate whorl about 17) rounded 

 retractively arcuate riblets, with wider interspaces somev/hat nodu- 

 lous at intersections with the spiral cords, and becoming obsolete on 

 the last whorl, on the spire they extend from sutm^e to sutm^e and 

 on the last whorl to the base; there is also irregular incremental 

 thi'eading; apertm-e ovate, lips simple, sharp, a shallow sulcus next 

 the anterior end of the pillar lip; height, 6.5; diameter, 2.5 mm. U.S.

Shell small, with a very pale olivaceous periostracum, acute, slender, 

 with about eight romided whorls, the apex eroded ; suture distmct, deep, 

 marked by a small thread against which it is laid ; spiral sculpture of 

 (on the spire thi-ee) flattish cords with subequal channeled inter- 

 spaces, on the last whorl four, the third at the periphery largest; 

 axial sculpture on the upper spire of obscure radials which undulate 

 the cords but do not show in the interspaces, and later are obsolete; 

 there are also very fine silky regular incremental lines; the base is 

 discoid, slightly flattish, unperforate, the aperture ovate, simple, the 

 outer lip thin sharp, the inner lip white, glazed; the pillar short, thick, 

 and attenuated, the lip beyond it produced, patulous; height, 10;
