white (figs. 8, 9). According to Garrett this form is very 

 abundant. 



6, form zonata. Yellow, with the base and a narrow or 

 rather wide sutural 'band brown, purple-brown or rose-color, 

 mouth bicolored. Common (fig. 10, 11). Varies in size 

 from 24 x 13.5 to 21.5 x 12.5 mm. 



7, form cognata 'Pse.' Garrett. Often smaller, length 

 9.5 to 23 mm., yellow with the suture tinted with rose or 

 purplish; aperture white (pi. 22, figs. 12, 17; pi. 33, fig. 3), 

 "Very common in Faahiti valley, but rare elsewhere" (Gar- 

 rett). This small form varies to light yellow with pallid 

 spire, and to yellow with purple or roseate spire, like form 

 bicolorata ; or it may have the color of form no. 6. 



8, form estaUiaiia, 'Garrett' Smith. Shell small, thin, 

 whitish-corneous or yellowish, with the base and a band be- 

 low the suture rose or dull purple, leaving the lighter tint in 

 a broad zone or band. Occurs in Faahiti valley only (figs. 

 13, 14). 



This form varies to yellow or corneous-yellow shells, with 

 the spire corneous or more or less purple-tinted, lip whitish 

 or with a purplish tint (figs. 15, 16).

"Var. a, purple-brown. Var. &, whitish, sutures and base 

 of the last whorl roseate, epidermis yellow." (Brod.).

The shell is perforate, oblong-ovate, very thin, pellucid, 

 slightly yellowish corneous, sometimes with a pale ruddy tint 

 at the apex, the suture bordered with an opaque white line. 

 Surface lustrous, showing fine growth-lines, and very close, 

 minutely crimped, spiral striae throughout. Whorls 4^, con- 

 vex, the last one compressed or somewhat flattened below 

 the periphery, therefore unusually convex close to the perfora- 

 tion. The aperture is quite oblique, ovate ; peristome thin, re-
