NO. I ACHATINELLA APEXFULVA DIXON — WELCH IO9 



lip and columella callus white or a faint shade of pale vinaceous fawn. 

 Length 18.0 mm., greater diameter 12.7 mm., spire height 9.8 mm., 

 number of whorls 6^. The usual form is not determined because of 

 a lack of sufficient number of adult shells. 



An obese shell (pi. 9, fig. 13a) and a variant of the usual pattern 

 which does not have the lip fully developed, measures: Length 

 17.1 mm., greater diameter 13.5 mm., spire height 8.6 mm.; penulti- 

 mate whorl white axially streaked with natal brown and spirally 

 lined with white, last whorl chamois spirally banded and axially 

 streaked with hay's brown above the periphery, the peripheral band 

 is chamois axially streaked with avellaneous, below the periphery the 

 subperipheral band is hay's brown, the remainder of the base is 

 dark olive buff, lined and streaked with hay's brown. The light color 

 pattern on 17 percent of the shells (pi. 9, fig. 13&) is similar to 

 A. a. versicolor and has the last two whorls above the periphery 

 white, axially streaked and spirally lined with vinaceous fawn color 

 and army brown, on the last whorl below the periphery the ground 

 is colonial buff spirally banded with hay's brown about the base and 

 faintly axially streaked and spirally banded with light drab. 



Thirty-eight percent of the shells have a pattern similar to that of 

 plate 9, figure 13c, which shows a narrow shell; the first two post- 

 embryonic whorls are pale smoke gray, spirally lined and streaked 

 on the first postembryonic whorl with warm sepia, white, and cinna- 

 mon buff, penultimate whorl axially streaked with zigzag and straight 

 streaks of natal brown and army brown, and spirally banded with a 

 band of white below the suture and subsutural bands, last whorl 

 drab gray axially streaked and lined with benzo brown and hair 

 brown, and banded below the subsutural band and at the periphery 

 with white, tinted with tilleul buff ; the sutural and subsutural bands 

 form a single wide band, which is natal brown axially streaked with 

 white on the first half of the penultimate, and wood brown axially 

 streaked with vinaceous buff on the last whorl and a half.

Area 60: Waikakalaua-South Kaukonahua Ridge, locality 261*, 

 approximate elevation 1,450-1,529 feet, 1932; 260-261?, approxi- 

 mate elevation 1,100-1,529 feet, Meinecke, 1913. Locality 261 may 

 not be very accurately plotted but is probably somewhere between 

 localities 260 and 261 (figs. 5, 5a, p. 105).
