3. Aclis succincta, n. sp. Plate XXVIII. fig. 4. 



Shell very small, turreted, perforate, hyaline and somewhat 

 shining. Sculpture consisting of spiral threads, one upon the 

 middle of the shoulder, the second (most prominent of all) on 

 the angle of the shoulder, the third (slightly finer) a little below 

 the periphery, and the fourth just above the suture ; base with 

 a few additional spiral lirae ; the whole crossed by oblique rather 

 distant axial lines reticulating the interstices and extending 

 over the base ; the axial sculpture by far not so conspicuous 

 as the spiral. Colour light-horny. Spire turriculate, much 

 higher than the aperture ; outlines straight. Protoconch 

 small, obtuse, spirally sharply ridged. Whorls 6. regularly in- 

 creasing, distinctly shouldered, and angularly narrowed again 

 below the periphery ; base convex. Suture distinct, margined 

 above by the fourth spiral. Aperture subvertical, oval. Peristome 

 discontinuous, sharp. Columella vertical, somewhat arcuate, a 

 little broadened and subtruncate below. Perforation narrow, 

 open. Operculum unknown.
