Area 31 : Kalauao-Waimalu Ridge, locality 190A*, elevation 

 1,750-1,800 feet, 1932; 191 A*, elevation 1,600 feet, 5 sinistral 1932, 

 all Meinecke-collected (figs. 4, 4a, p. 53). 



The color pattern of the shells in this sector are vi^hite shells banded 

 or tinted with yellov^^ or banded w^ith brov^n, A usual pattern in 

 locality 190A* (pi. 5, fig. 22) has the postembryonic whorls white, the 

 last half of the first postembryonic whorl and the first half of the 

 penultimate faintly lined and banded with tawny, the last half of the 

 penultimate faintly banded and lined with cream bufif, the first half of 

 the last whorl mustard yellow with a peripheral band and supraperiph- 

 eral line of buckthorn brown, last half whorl white tinted with mustard 

 yellow, with the peripheral band buckthorn brown, behind the edge 

 of the lip a streak of mars brown. A brown color pattern (pi. 5, 

 fig. 22a) has the postembryonic whorls above the periphery antimony 

 yellow axially streaked and lined with amber brown ; impressed sutural 

 band chestnut; last whorl and a half at the edge of the periphery 

 and below the periphery white tinted with cream color, in the umbili- 

 cal region a patch of amber brown. A white color form (pi. 5, 

 fig. 22b) resembles A. a. ovum. The entire shell is white, tinted on the 

 last whorl with mustard yellow, last fourth whorl faintly banded with 

 mustard yellow, behind the edge of the lip mars brown. 



In the higher locality of 191 A*, the usual color pattern (pi. i, fig. 

 36) is a white shell banded on the last whorl above the periphery and 

 all below the periphery with mustard yellow. The shells in the upper 

 region are all sinistral; in 190A* they are all dextral. 



ACHATINELLA APEXFULVA WAIMALUENSIS, new subspecies 



Plate i, Figure 45 ; Plate 5, Figures 25, 25a 



The shell looks like a form of A. a. ovum or A. a. aureola and their 

 varieties, but is distinct from them in having the first postembryonic 

 whorl banded with brown so that the whorl stands out, being darker 

 than the whorls above and below it. The A. a. ovum and A. a. aureola 

 forms have a color pattern which usually darkens consistently on the 

 later whorls. 



The embryonic whorls of the holotype (pi. i, fig. 45) are cartridge 

 buflf; first postembryonic whorl banded on the lower portion of the 

 whorl with ochraceous tawny, the band decreasing from three- fourths 

 the width of the whorl to half its width, on the white penultimate and
