 sutural band of fawn color two lines of tilleul bufif, on the last whorl 

 the ground above the periphery tilleul bufif faintly axially streaked 

 with straight and zigzag streaks of avellaneous, base mustard yellow 

 with a band of avellaneous just below the subperipheral mustard 

 yellow band, umbilical region lined with tawny. 



An elongate shell (pi. ii, fig. 24b) and a variant of figure 24a has 

 the postembryonic whorls white, tinted, faintly lined, and faintly 

 axially streaked with tilleul bufif or vinaceous bufif ; sutural and wide 

 subsutural bands and the line below the subsutural band wood brown ; 

 on the last whorl a thin band at the edge of the periphery of drab, 

 below which the ground is chamois banded with wood brown. Length 

 18.2, greater diameter 11.8 mm., spire height 10.3 mm. 



The lightest color pattern (pi. 11, fig. 24c) has the white post- 

 embryonic whorls above the periphery lined with a faint line of 

 naples yellow on the last whorl, below the periphery naples yellow 

 with a central line of cinnamon, and a line and a band of russet in 

 the umbilical region ; sutural and wide subsutural bands chocolate. 



A yellow color pattern (pi. 11, fig. 24c?) has the first two post- 

 embryonic whorls pale pinkish bufif, last whorl light bufif finely spirally 

 lined and axially streaked with ochraceous tawny, on the base a thin 

 band of russet and faint lines of tawny ; impressed sutural band and

 Plate 3, Figure 35; Plate ii. Figure 34 



The form is closely related to A. a. kahukuensis but dififers in color 

 pattern. The color pattern of the holotype resembles that of A. a. 

 oiocnsis, but ihiihiensis has a base colored a lighter shade of yellow. 

 The embryonic whorls of the holotype (pi. 3, fig. 35) are cream color ; 

 postembryonic whorls warm blackish brown; impressed sutural band 

 cinnamon; edge of the periphery and all below the periphery of the 

 last whorl mustard yellow, banded with a central band of warm black- 

 ish brown and two lines of mikado brown ; Hp and columella callus 

 light vinaceous fawn, lip streaked with white. Length 17.7 mm., 

 greater diameter 11.6 mm., spire height 9.6 mm., number of whorls 6.
