" This shell belongs to the same group as the last {A. globulus) 

 and is very close to A. creuatus, mihi (vide Plate III. fig. 5, 

 J. A. S. B. Pt. 2, 1871), but the longer sutural tube and the 

 strongly crenated peristome of crenatus mark the distinction."

 thick, translucent, pale corneous, pink or white, quite smooth, with 

 shining lustre in fresh shells, with very strong regular filiform 

 costulation on the tumid portion of the last whorl, the sculpture 

 terminating abruptly both in front and behind with the exception 

 of some raised striae close behind the termination of the sutural 

 tube ; indistinct ribbing near the umbilicus. Spire conoid, apex 

 obtuse ; suture impressed ; whorls 4-4|, rounded, last very slightly 

 swollen, constricted and enlarging slightly again near the aperture. 

 Constriction smooth, rather short; sutural tube moderate, com- 

 mencing at -045 inch distance from the mouth. Aperture slightly 

 oblique, a perfect circle ; peristome double, thick, inner continuous, 

 projecting, slightly expanded, the outer retrorelict. Operculum 

 horny, multispiral, concave in front ; smooth behind, no central 

 boss.
