 mantle and foot brownish-black " (Newcomb). 



The locality given by Mighels is certainly erroneous. His 

 type is lost, but the description applies to shells from Lahaina. 

 This place, or rather the valley back, may be taken as type 

 locality. The shell is turrited, the lateral outlines straight 

 or slightly concave. The first % whorl is smooth, corneous 

 and convex; the second whorl is flat, finely striate and irreg- 

 ularly, coarsely but not strongly costate, and usually has 

 some blackish longitudinal streaks (pi. 56, figs. 6, 8). Suc- 

 ceeding whorls are strongly convex, white or very pale- 

 yellow, copiously marked with a tracery of black or blackish- 

 olive zigzag or angular lines which may extend over the base, 

 or stop short at the periphery in front. The last whorl is 

 especially convex. The aperture is either pink or white 

 within. Columellar lamella strongly developed, emerging 

 to the edge of the well-refiexed columellar lip. Contour var- 

 iable. 



Length 16, diam. 10 mm. ; whorls 614. 



Length 15.3, diam. 9.5 mm. ; whorls 



Length 14.3, diam. 7.7 mm. ; whorls 



In some specimens, also from Lahaina, the dark lines are 

 broken into dots (figs. 4, 9). 



An embryonic shell (pi. 56, figs. 6, 8) removed from one 

 of these shells is figured. The second whorl is strongly cos- 

 tate and copiously marked; the columellar lamella is ex- 

 tremely small and low; axis perforate. Length 3.8 mm.; 2~y 2 

 whorls. The acceleration of the color-pattern is a marked 

 feature. 



Figures 1 to 6 are from one lot of Lahaina shells. Fig. 1 

 may be considered typical. Some received from Newcomb, 

 without exact locality, are larger, length 19, diam. 10.3 mm., 

 typical in color. In some shells, figs. 3 and 5, the dark mark- 

 ings are distinctly sunken.
