Gulch, because this region is often referred to as Wainialu by 

 some collectors. The race may have come from somewhere near 

 area 35 because the shell looks so like forms of A. a. turgida (fig. 4a, 



P-53)- 



The lightest color pattern and extreme obese form (pi. 6, fig. 15) 

 has the postembryonic whorls pale pinkish cinnamon, spotted on the 

 first two postembryonic whorls and banded just below the impressed 

 sutural band on the last whorl with cinnamon bufif, below the periph- 

 ery of the last whorl faintly lined with dots of cinnamon bufif. 

 Length 17.2 mm., greater diameter 13.0 mm., spire height 9.0 mm. 



An elongate dextral (pi. 6, fig. 15a) measures: Length 18.8 mm., 

 greater diameter 11.5 mm., spire height 10.7 mm.; embryonic whorls 

 worn; postembryonic whorls pale pinkish cinnamon axially streaked 

 with sayal brown, banded on the last half whorl below the periphery 

 with a band of verona brown. 



Plate 6, figure i^h, shows an obese sinistral specimen with a color 

 pattern similar to plate i, figure 40. An elongate sinistral (pi. 6, 

 fig. 15c) with a color pattern similar to the holotype, measures: 

 Length 19.1 mm., greater diameter 11.8 mm., spire height ii.o mm.

 p. 297, pi. 59, fig. 17 (only), 1914. 



The holotype (pi. 5, fig. 9) in the British Museum, marked with 

 a red dot of sealing wax, is entirely white except for the black lip. 

 Length 19.4 mm., spire height 10.3 mm., number of whorls 6\. The 

 other two shells in the type lot are white dextral specimens. One is not 

 adult, the other (pi. 5, fig. 10) is fully developed and marked specimen 

 A; the lip is black. Length 17.8 mm,, greater diameter 12.7 mm., 

 number of whorls 6\. 



Distribution, area 22 : North-Central Halawa Ridge, locality 

 162C*, elevation 1,400-1,450 feet, Meinecke, 1930 (figs. 4, 4a, p. 53). 

 Also collected by Wilder, BBM 50525. 



The holotype probably came from area 22 because that area is 

 the lowest containing sinistral shells. The dextrals in the type lot 

 may have come from a lower locality somewhere near area 21. Only 

 six live shells are known to come from area 22. The colors are 

 equally divided between the typical white ovum pattern of plate i,
