eral band and having a different range of color patterns. The shell 

 has characteristic white embryonic whorls and contrasting dark brown 

 postembryonic whorls. This subspecies is usually found mixed 

 with A. a. coniformis in the GuHck lots although some lots of 

 apexalba contain no forms of A. a. coniformis. I have separated 

 apexalba from coniformis because of the fact that apexalba has 

 a crisscross color pattern in which the spiral bands are broken 

 or flecked by dark and light axial streaks somewhat resembling A. a. 

 versicolor. The shell of apexalba has a rough, coarse, or broken 

 pattern, whereas coniformis has a solid, finely axially streaked even 

 color. A few specimens are found which might be put in either 

 subspecies. These are probably intermediate forms between the two 

 races. 



The embryonic whorls of the holotype (pi. 2, fig. 35) are pale 

 pinkish buff; first two postembryonic whorls light drab axially 

 streaked with hair brown and benzo brown spirally lined with a 

 central line of white, on the penultimate whorl a white subsutural 

 band broken by dark axial streaks, last whorl above and just below 

 the periphery spirally banded with light drab and drab axially streaked 

 with snuff brown, flecked and spirally lined with white, last half 

 whorl darkens to snuff brown, base snuff brown spirally banded with 

 avellaneous and tilleul buff; impressed sutural band chestnut on the 

 first two postembryonic whorls, on the last whorl impressed sutural 

 band the ground color except the upper edge, which is fawn color; lip 

 and columella callus pale vinaceous fawn. Length 18.5 mm., greater 

 diameter 11.7 mm., spire height lo.o mm., number of whorls 6\. 



Distribution, area ? : Type locality Wahiawa, Gulick. Also Kalai- 

 koa, Ahonui, Gulick. The last two localities are probably wrong, if 

 Wahiawa is correct. 



The darkest color pattern and elongate form of the shell (pi. 9, 

 fig. 26) measures : Length 17.9 mm., greater diameter 11.3 mm., spire 

 height 10.8 mm. ; first two postembryonic whorls drab spirally banded 

 with fawn color and axially streaked with verona brown, last whorl 

 saccardo's umber, banded with fawn color above the periphery, be- 

 low the periphery a band of white and lines of white ; impressed 

 sutural band russet lightening in color at the extreme upper edge to 

 tawny. 



A light color pattern (pi. 9, fig. 26a) has the first postembryonic 

 whorl benzo brown with a central white line, penultimate whorl 

 white axially streaked with hair brown and spirally lined with a central 

 band of white, last whorl tilleul buff, spirally lined with verona brown 

 and axially streaked with drab, base banded with a hue between benzo
