bands light buff, the remainder of the whorl hair brown, chaetura 

 drab, or warm sepia, axially broken by straight and zigzag streaks of 

 pale pinkish buff or white, edge of the periphery banded with white; 

 lip and columella callus vinaceous fawn. Length 17.2 mm., greater 

 diameter 12.0 mm., spire height 9.2 mm., number of whorls 6^. 



Distribution, area 67 ? : North Waiawa Stream, locality 230E-1-2 ?, 

 approximate elevation 1,050-1,900 feet, "ridge back of tunnel-man's 

 house," found on lehua {Metrosideros), Lemke, 1933, also 1932. The 

 exact location of this race must be checked. Different lots from the 

 general region of area 67? contain varying proportions of different 

 color patterns which indicates slightly different localities (figs. 4, 4a, 



P- S2,)- 



The darkest color pattern (pi. 8, fig. 22) has the first postembryonic 

 whorl light buff finely axially streaked or tinted with ochraceous 

 tawny, impressed sutural band ochraceous tawny, last two whorls 

 bone brown, streaked with zigzag lines of light buff, sutural and 

 subsutural bands light buff axially streaked with ochraceous tawny 

 on the penultimate whorl, on the last whorl light buff, last whorl 

 banded at the edge of the periphery with white; lip and columella 

 callus light vinaceous fawn. 



The usual color pattern of a dextral shell (pi. 8, fig. 22a) has the 

 first postembryonic whorl white, tinted with pinkish buff, sutural 

 and subsutural bands ochraceous tawny, penultimate whorl between 

 white and pale pinkish buff tinted and streaked with cinnamon buff, 

 sutural and subsutural bands cinnamon buff, just above the edge of 

 the periphery a band of benzo brown, streaked with zigzag lines of 

 white, last whorl above the white peripheral band pale cinnamon pink 

 tinted with pinkish buff, supraperipheral band and all below the 

 periphery natal brown spirally lined and streaked with zigzag axial 

 lines of pallid mouse gray and white. 



I have a number of lots before me collected by Lemke at different 

 times from the region of the type locality. Lot no, Lemke collection, 

 has seven specimens, all except one with the typical pattern of 

 plate 2, figure 5. In connection with lot 173, Lemke collection, Lemke 

 states that he collected over a wider range, going up a spur ridge to 

 the top of a larger ridge from which the spur branched. In this lot 

 45 percent of the shells have the typical patterns of A. a. lemkei; 

 the remainder have white, gray-lined color patterns which possibly 

 come from a locality at a higher elevation (see pi. 8, figs. 22&, 22c). 

 Although I am calling these two shells A. a. lemkei, they quite pos- 

 sibly belong to another race occurring above lemkei, the two forms 

 not being mixed except at the border of an upper and lower area.
