impressed sutuial band white ; lip and columella callus light vinaceous 

 fawn. Length 20.2 mm., greater diameter 13.2 mm., spire height 

 10.7 mm., number of whorls 6h 



Distribution, area 83b??: Type locality Kalaikoa, Gulick; also 

 Ahonui, Gulick. The type locality containing a pure race of pink 

 shells of the typical A. a. lilacea pattern has not been located in 

 recent years. Meinecke in locality 280* (fig. 5, p. 105), North Kau- 

 konahua-Poamoho Ridge, BBM 12 1982, found two specimens of 

 typical A. a. lilac ca mixed with A. a. lilacea var. i. This indicates 

 that Gulick's type locality was probably somewhere in the region of 

 North Kaukonahua Stream which was all or part of Gulick's Ahonui, 

 and not in Kalaikoa. The possible region of the type locaHty area 

 83b?? has been plotted on figure 7, (p. 194). 



The usual form of A. a. lilacea (pi. 3, fig. 2) has the embryonic 

 whorls pale pinkish buff; postembryonic whorls seashell pink axially 

 streaked with buff pink ; impressed sutural band white ; lip and 

 columella callus shell pink. Length 18.7 mm., greater diameter 12.2 

 mm., spire height lo.o mm., number of whorls 6. A narrow specimen 

 (pi. 10, fig. 9) measures: Length 18.0 mm., greater diameter 11.8 

 mm., spire height ii.o mm. An obese specimen (pi. 10, fig. 10) 

 measures: Length 18.2 mm., greater diameter 12.8 mm., spire height 

 10.0 mm. The color pattern of figures 9 and 10 is similar to that of 

 plate 3, figure 2, except that the impressed sutural band is the same 

 as the rest of the whorl. 



One of the Meinecke pink shells (pi. 10, fig. 11) from locality 280" 

 has the embryonic whorls white ; postembryonic whorls pale salmon 

 color ; impressed sutural band the same as the rest of the whorl. 



ACHATINELLA APEXFULVA LILACEA var. i 



Plate 3, Figure 3 ; Plate 10, Figures 12-13 



Area 83: North Kaukonahua-Poamoho Ridge, locality 280-1- 

 280*, approximate elevation 1,450 feet, Russ, 1929-1933; 280*, eleva- 

 tion 1,350-1,450 feet, Meinecke, 1932. Also collected by Wilder, 

 BBM 50585. 



Area 83a : North Kaukonahua-Poamoho Ridge, locality 281-2*, 

 elevation 1,500 feet, 1932, BBM 121987, 121988; 281-1, elevation 

 1,500-1,550 feet, Meinecke, 5 dextral 1933 (figs. 5, 5a, p. 105). Lo- 

 cality 281-2*, plotted from memory, probably should be below locality 

 281-1. 



The shell is very similar in form and color pattern to typical 

 A. a. lilacea, differing in having a bluish-gray hue instead of a pinkish 

 color pattern. This race is probably intermediate between A. a. lilacea 

 and A. a. lilacea var. 2.
