18. M. PAZI ' Gundlach ' Pfr. PL 21, figs. 7, 8, 9, 10, 12. 

 Shell shortly rimate, high-conic, rather solid. Whitish, 



with a dark chestnut band below the periphery, another 

 around the umbilical area, the base elsewhere radially 

 streaked ; above the periphery there are usually several lighter 

 bands, or bands of spots on oblique streaks, sometimes want- 

 ing; apical whorls perfect, black-brown. Surface glossy, 

 almost smooth. Spire straightly conic, the whorls but slightly 

 convex, the last well rounded. Suture with a crenulate border 

 below. Aperture slightly oblique, brown or ochraceous within, 

 the peristome white, thin-edged, rather widely expanded, the 

 columellar margin triangularly reflexed and excavated at the 

 insertion. 



Length 15, diam. 6.5 mm., whorls 9%. 



Length 11, diam. 5 mm., whorls 9.

The peristome is more expanded, and the columellar lip 

 more flatly reflexed than in pictus and parallelus, both of 

 which are very closely related to pazi. There is wide varia- 

 tion in the color-pattern, which is sometimes reduced to the 

 two basal bands. A whorl or two below the brown apical 

 whorls are broadly flamed with brown and white.

Shell shortly rimate, turrite, slightly solid. Whitish, with 

 a dark chestnut band below the periphery, another around 

 the umbilical area, the rest of the base being radially striped, 

 and having three dilute-brown bands above, crossed by chest- 

 nut streaks, which are toothed on the right side at the posi- 

 tions of the bands. Apical 2 or 2% whorls generally lost, 

 but when retained they are smooth and pale, with a reddish 

 crown; following whorl blackish, the next 2 or 3 dark and 

 white flamed. Suture crenulate. Surface weakly striate on 

 the earlier whorls, smoother and glossy below, the last one
