Shells with color patterns very similar to that of A. a. virgatifulva 

 var. 2 are found in lots of shells from Waikakalaua Stream, Wilder, 

 BBM 50571, and South Kaukonahua Stream, Wilder, BBAI 50573 

 (probably the Waikakalaua-South Kaukonahua Ridge). 



The shell is closely related to A. a. virgatifulva, but differs in having 

 a light tan streaked color pattern instead of a dark brown streaked 

 one, and a light impressed sutural band instead of a dark brown 

 sutural band. Specimens of A. a. virgatifulva are usually mixed with 

 this form. Although the color pattern is very distinct and the form 

 is undoubtedly a distinct one, I shall consider it a variety of A. a. 

 virgatifulva until a locality is found that contains shells of A. a. 

 virgatifulva var. 2 not mixed with A. a. virgatifulva. Most of the 

 localities at lower elevations in areas 74, 57, 75, and 60 are wide locali- 

 ties and little carefully plotted material is at my disposal from this 

 section. 



The usual form (pi. 2, fig. 17) of the light color pattern has the 

 embryonic whorls bicolored, first embryonic whorl cinnamon drab. 

 next whorl upper half white, lower half .shaded with natal brown, on 

 the last embryonic whorl the lower band fades out and the whorl is
