rubidipicta near the head of this subridge on the Nuuanu-Kapalama 

 Ridge. Further collecting will establish the exact location of this 

 race. 



The specimens of A. a. vittata from Nuuanu collected by Gulick 

 closely match the holotype. The shells may be dextral or sinistral. 

 A. sinistral specimen (pi. i, fig. 13), is very similar to the color 

 pattern of the type; postembryonic whorls white, lined and streaked 

 with cinnamon bufif or pinkish buflf and lined with mikado brown. 

 A darker color pattern (pi. 4, fig. 18) has the penultimate whorl 

 banded with pinkish bufT shading to avellaneous and fawn color on 

 the last whorl ; impressed sutural band and subsutural band pale 

 pinkish bufif. 



The R. A. Cooke and C. M. Cooke, Jr., lots are not typical vittata 

 but contain patterns similar to those of typical vittata. The locahty 

 is a wide one and probably represents a mixture of typical vittata 

 with typical rubidipicta patterns. In the C. I\I. Cooke lot, which may 

 represent a collection of shells taken mostly from the lower portion 

 of locality lOoE-i*, 36 percent of the shells have a pattern similar to 

 that of plate 4, figure 19, penultimate whorl light buff banded with 

 white, the last whorl banded with white below the subsutural band 

 of light buff, at and below the periphery banded and lined with 

 ochraceous tawny and tawny axially streaked with light buff, base 

 banded with white, and lined and banded with mars brown. A rare 

 brown pattern (pi. 4, fig. 19a) has the last whorl and a half colored 

 light buff below the suture, just above and below the periphery the 

 ground is axially streaked and banded and tinted with tawny and 

 russet. 



In the R. A. Cooke lot color patterns are closer to A. a. rubidipicta 

 and probably come from a region adjacent to area 11. The typical 

 form and color pattern of the shell in the R. A. Cooke lots (pi. 4, 

 fig. 20) has the penultimate whorl white, lined with cinnamon buff, 

 impressed sutural band cinnamon, last whorl above the periphery 

 pale pinkish buff lined with pinkish buff" and verona brown, edge of 

 the periphery banded with vandyke brown and a band of white, sub- 

 peripheral band vandyke brown, remainder of the base white, sutural 

 band pinkish cinnamon. Length 18.7 mm., greater diameter 13.0 mm., 

 spire height 9.5 mm. The shell may have an entirely white ground 

 (pi. 4, fig. 20a), the last whorl profusely lined with walnut brown 

 and chocolate; impressed sutural and subsutural bands light buff". 

 A dark color pattern (pi. 4, fig. 20b) has the penultimate whorl 

 warm buff', banded and streaked with ochraceous tawny on the upper
