NO. I ACHATINELLA APEXFULVA DIXON — WELCH 93 



In the small series of shells in the Gulick collection in the Bishop 

 Museum that can safely be identified as A. a. polymorpha, the typical 

 pattern is a rare one and the range of color patterns is not determined. 

 Usually, in Waiawa where forms similar or closely related to 

 A. a. polymorpha occur, such as A. a. polymorpha var. i, A. a. 

 flavitincta, and A. a. lemkei var. i, the sutural band is tan or brown. 

 Exceptions to this rule are the shells of plate 8, figures 22b and 22c, 

 of A. a. lemkei. But these two shells may belong to a race occurring 

 at a higher elevation than A. a. lemkei. Since rare tan patterns occur 

 with the usual banded patterns in area 68 and 69, which are very 

 similar to the color patterns of the shell described as Apex neglectus 

 by Smith, I believe that neglectus is a rare light tan color form of 

 A. a. polymorpha. 



There are four specimens of Apex neglecta in the type lot in the 

 British Museum. One specimen marked "x" by myself is considered 

 the lectotype, because it agrees best with Smith's original figure re- 

 produced in this paper on plate 8, figure 24. The lectotype (pi. 8, 

 fig. 24) has the embryonic whorls cartridge buff banded on the last 

 embryonic whorl on the lower half of the whorl with cream buff; 

 first two postembryonic whorls finely lined with cinnamon buff, last 

 whorl pale olive gray axially streaked and faintly lined with light 

 olive gray ; impressed sutural band shades from hazel to carob brown 

 on the last two whorls ; subsutural band on the last whorl cinnamon 

 buff; lip and columella callus vinaceous fawn. Lengtl? 17.2 mm., 

 greater diameter 12.0 mm., number of whorls 6. Another shell from 

 the type lot (pi. 8, fig. 25) has a convex spire, and a color pattern 

 similar to the lectotype. 



A dextral specimen in the Gulick collection (pi. 8, fig. 26) has the 

 embryonic whorls white; postembryonic whorls pale pinkish buff 

 spirally banded and lined with cinnamon or cinnamon buff above the 

 periphery ; the impressed sutural band mikado brown.

The usual color pattern of the shell (pi. 8, fig. 29) resembles 

 A. a. polymorpha except that the banding is a lighter shade of gray, 

 and the base is white ; the shape of the last whorl is rounded and the 

 base is not flattened. Upper half of the first embryonic whorl white, 

 lower half cream color, remaining embryonic whorls white, banded on 

 the lower fourth of the whorl with warm buff; first half postembry- 

 onic whorl white, last half pinkish buff, first half of the penultimate
