NO. I ACHATINELLA APEXFULVA DIXON — WELCH 89 



The usual color pattern and obese form of the shell is shown on 

 plate I, figure 54, postembryonic whorls white; impressed sutural 

 band on the first postembryonic whorl light pinkish cinnamon, on the 

 remaining whorls the pinkish cinnamon color is confined to the upper 

 edge of the band and fades out on the last whorl ; last whorl banded 

 above the periphery with hair brown, below the periphery hair brown 

 streaked with white and lined with natal brown. Length 17.6 mm., 

 greater diameter 13.7 mm., spire height 8.6 mm. The embryonic 

 whorls may be darker and the postembryonic whorls lighter (pi. 8, 

 fig. i6a) ; embryonic whorls pale pinkish buff shading to ochraceous 

 buff, banded at the suture on the last embryonic whorl with sayal 

 brown ; first postembryonic whorl snuff brown lined with white, 

 penultimate whorl white, banded and lined with sayal brown, last 

 whorl white, lined with sayal brown and banded below the periphery 

 with warm sepia ; impressed sutural band verona brown fading out to 

 sayal brown on the last half whorl where it occupies only the upper 

 edge of the sutural band,

The shell is closely related to A. a. chromatacme, but differs in the 

 gray banding of the postembryonic whorls, and by having white em- 

 bryonic whorls. The embryonic whorls of the holotype (pi. 2, fig. 3) 

 are white ; first postembryonic whorl white, fined with russet ; on the 

 last two whorls the impressed sutural and wide subsutural bands 

 are white, except on the last half whorl, where the lower edge of the 

 sutural band is edged with a line of wood brown ; the remainder of 

 the shell shades from brownish drab on the first half of the penulti- 

 mate to drab gray axially darkened by streaks of light drab on the 

 remaining whorls ; Hp vinaceous fawn. Length 18.0 mm., greater di- 

 ameter 12.5 mm., spire height 9.3 mm., number of whorls 6^. 



Distribution, area 63 ? : North-South Waiawa Ridge, type locality 

 231B*, elevation 1,000-1,100 feet, 1929; also locality 232B*, eleva- 

 tion 750-850 feet, Meinecke, 1929. The Meinecke localities were 

 plotted in 1933 and may be plotted too low and should be checked. 

 Also collected in Waiawa by Thurston, BBM 130590. 



Area 64 : South Waiawa Stream, locality 237A-1*, elevation 750- 

 850 feet, 3 sinistral, H. Lemke, 1932 ; on a spur ridge of the North- 

 South Waiawa Ridge, locality 233B-1*, elevation 1,350-1,400 feet, 

 H. Lemke and H. Lemke, Jr., 1932. Area 62, ? is possibly wrongly 

 plotted and perhaps should be placed higher or nearer area 64 

 (figs. 4, 4a, p. 53).
