of 2% to 3 whorls, the last with some faint subsutural plica- 

 tion, the rest smooth and convex. The fourth whorl is plicate 

 below the suture, the plicae mostly rather short; on subse- 

 quent whorls they become larger, but hardly reach the suture 

 below. On the last whorl there are 2 or 3 fine plicae in 1 

 mm. ; they reach about to the middle, or in places may be 

 much shorter; they show some fine transverse crinkling near 

 the suture, and are indistinctly cut by a few spiral depres- 

 sions in some places. The lower half of the whorl is smoother, 

 with low wrinkles of growth only. The suture is weakly or 

 very weakly crenulated ! by the plicae. The aperture is nar- 

 row, the columella straight or concave. 



Length 54, diam. 19.5, aperture 29 mm. 



Length 53.3, diam. 19, aperture 26 mm. ; whorls 7%. 



Length 50.5, diam. 17, aperture 25 mm. ; whorls 7%.

In shape the specimens vary from fusiform to saccate. The 

 fine plication is well developed only near the suture, and is 

 nowhere conspicuously decussated.

Shell cylindric-oblong, slender, rather thin, very glossy, 

 fleshy-brown, marked with several white lines, indicating for- 

 mer peristomes, on the last whorl; the suture pale-bordered. 

 Spire convexly long-conic, the apex rounded, obtuse. The 

 first 2y 2 to 3 whorls are smooth. The later whorls have a very 

 even sculpture of smooth, rounded rib-striae, 2% to 3 in 1 mm. 

 on the last whorl, weak or subobsolete near the columella and 

 base. There is some very faint crinkling of the intervals near 

 the suture, which is only weakly crenulated by the striae. 

 The aperture is very long and narrow ; outer lip white-edged ; 

 columella strongly concave. 



Length 37, diam. 12, aperture 19.5 mm. ; whorls 7. 



Length 44, diam. 14.5, aperture 21.5 mm. ; whorls 7%.
