NO. I ACHATINELLA APEXFULVA DIXON WELCH 85 



brown; columella callus light vinaceous fawn. Length 20.1 mm., 

 greater diameter 13.1 mm., spire height ii.i mm., number of 

 whorls 67. 



Distribution, area 42 : Manana-Waiawa Ridge, locality 232, ele- 

 vation 1,250 feet, 1929, 3 sinistral 1933; 233, elevation 1,350 feet, 

 I dextral, 6 sinistral 1929; 234*, elevation 1,150-1,250 feet, 1929; 

 235*, elevation 1,150-1,250 feet, 1929; 236*, elevation 1,050-1,150 

 feet, 1929, all collected by Meinecke (figs. 4, 4a, p. 53). Lectotype, 

 ANSP 108804, collected in Waiawa by Kuhns for Thaanum. 

 Meinecke did a great deal of collecting with Kuhns and is familiar 

 with Kuhn's localities. One or several of the above lots surely repre- 

 sents a series from the type locality. Meinecke, BBM 121835-121836, 

 also reports this form from locality 230B?, elevation 1,000-1,150 feet, 

 on the North-South Waiawa Ridge, 1929, but I am inclined to believe 

 that the locality is wrongly plotted because of the wide difference be- 

 tween the color pattern of the shells of 230B* and the adjacent 

 localities of 231B* and 232B*. 



The exact region of the type locality is not known to me, so I have 

 selected locality 235 for a typical one, and shall describe the color and 

 size variation of the shells from that place. In the usual form of the 

 shell (pi. 6, fig. 21) and a color pattern occurring on 53 percent of 

 the shells, the embryonic whorls shade from pale pinkish buflf to tawny, 

 last embryonic whorl banded at the suture with white; on the first 

 postembryonic whorl and a half the impressed sutural band shades 

 from mikado brown to cinnamon, subsutural band extending to about 

 the middle of the whorl above the periphery, shades from cinnamon 

 buff to cinnamon, remainder of the whorl drab axially streaked with 

 cinnamon, last whorl and a half, impressed sutural and narrow sub- 

 sutural bands cinnamon, remainder of the whorl pinkish buff closely 

 axially streaked and finely spirally lined with drab, so that the color 

 looks at first glance to be solid drab, at the periphery a line and a 

 band of pale pinkish buff; Hp and columella callus light vinaceous 

 fawn. Length 19.5 mm., greater diameter 13.2 mm., spire height 

 10.5 mm. A narrow shell (pi. 6, fig. 21a) shows the darkest color 

 form of the brownish or tan color patterns; the postembryonic 

 whorls shade from walnut brown to burnt umber axially streaked with 

 light buff; impressed sutural band light buff. Length 19.7 mm., 

 greater diameter 12.7 mm., spire height ii.o mm. 



Forty-seven percent of the live shells in locality 235 have a gray 

 color pattern (pi. 6, fig. 21b) ; the embryonic whorls shade from pale 

 pinkish buff to russet; first postembryonic whorl shades from sayal
