NO. I ACHATINELLA APEXFULVA DIXON WELCH 3 1 



The postembryonic whorls of the holotype (pi. i, hg. i) are drab 

 gray shading to drab, axially streaked on the last two whorls with 

 snuff brown and bister, spirally lined with white ; impressed sutural 

 band cinnamon ; lip and columella callus fawn color. Length 17.3 mm., 

 greater diameter ii.f mm., spire height 9.3 mm., number of 

 whorls 6. 



Distribution, area i : Niu-Wailupe Ridge, type locaHty 41-4*, 

 elevation 1,659-1,750 feet, Meinecke, BBAI 120184, 120177, 1926, 

 also BBM 120197, 6 sinistral 193 1 ; Kului-Laulaupoe Ridge, Wai- 

 lupe, locality 41A-1*, elevation 1,800-2,000 feet, j\Ieinecke, BBM 

 120216-120217, 1926; Laulaupoe-Wailupe Ridge, Wailupe, 41B- 

 4*, elevation 1,950-2,000 feet, Meinecke, BBM 120225, 1926 (figs. 3,

The lightest color form of the shell (pi. 4, fig. i) has the postem- 

 bryonic whorls pale drab gray axially streaked with light drab ; im- 

 pressed sutural band pale pinkish cinnamon streaked with light pink- 

 ish cinnamon ; last whorl lined with white. This color pattern re- 

 sembles the light color pattern of A. a. zvaialaeensis (pi. 4, fig. 2), 

 but muricolor is definitely more lined and lacks the strong white 

 peripheral band. An obese shell (pi. 4, fig. la) measures: Length 

 17.3 mm., greater diameter 11.8 mm., spire height 8.6 mm. ; the post- 

 embryonic whorls strongly lined, last two whorls tilleul buff lined 

 and banded with wood brown, natal brown, snuff brown, and bister, 

 peripheral band white; lip and columella callus wood brown. 



A rare dark color pattern (pi. 4, fig. ih) occurs on 7 specimens out 

 of a total of 194 taken at various times from locality 41-4. The last 

 two whorls are drab lightly axially streaked with vinaceous and 

 sepia, faintly lined with pale pinkish buff.

This form is characterized by having a light yellowish- white ground 

 splotched or rarely banded on the last two whorls above the periphery 

 with reddish brown, and by having a dark reddish-brown band below 

 the periphery; the base may be banded or splotched with reddish 

 brown. 



The lectotype (pi. 4, fig. 9) is marked with an "x" by me. The last 

 two whorls are white streaked with splotches of walnut brown and
