be larger and less l)lunt than those of the typical form. Eight percent 

 of the shells are entirely white and are similar to plate 7, figure 210. 

 A dark banded form (pi. 7, fig. 21b) occurs on 30 percent of the 

 shells ; the postembryonic whorls shade from sudan brown axially 

 streaked with warm buff to carob brown on the last whorl and a half, 

 the edge of the periphery and below the periphery white, base banded 

 and lined with carol) l)rown. 



ACHATINELLA APEXFULVA EWAENSIS var. 3 



Platk 2, FiGUKi': II ; Plate 7, Figlres 25, 26 



Area 52: Waiawa-Kipapa Ridge, locality 243-2, elevation 1,500- 

 1,550 feet, Meinecke, 1933; 243-3-4*, elevation 1,500-1,620 feet, 

 Meinecke, 1929, 5 dextral, 5 sinistral; 243-4*, Welch, 1934 (figs. 5, 



5«. P- 105)- 



Area 52 contains forms (pi. 2, fig. 11) similar to typical A. a. 

 cwaensis, but differing in having the embryonic whorls not as 

 markedly banded with yellow, and in having the last whorl banded 

 with lighter reddish-brown bands. With the typical pattern are mixed 

 color patterns (pi. 7, figs. 25, 26), which resemble the shells of 

 area 72. 



The usual form and color pattern of the shell (pi. 2, fig, 11) has 

 the embryonic whorls bicolored, upper half or three-quarters white, 

 lower half or fourth of the whorl banded with yellow deepening to 

 chamois ; postembryonic whorls white, last whorl below the periphery 

 banded with chocolate; lip and columella callus pale grayish vina- 

 ceous. Length 18.7 mm., greater diameter 13.0 mm., spire height 

 9.3 mm., number of whorls 6^. 



Out of 16 specimens from locality 243-2, 12 are dextral, 8 of which 

 are similar to plate 2, figure 11. Three of the dextrals are similar 

 to the shell of plate 7, figure 25, which has the postembryonic whorls 

 white spirally lined and banded with olive buff, last whorl at the edge 

 of the periphery banded with white, below the periphery lined with 

 two lines of bone brown and banded with smoke gray, last half whorl 

 lined above the white peripheral band with a line of bone brown and 

 six lines of bone brown below the peripheral band. Length 19.0 mm., 

 greater diameter 12.5 mm., spire height 10.2 mm. 



The color pattern on three shells looks like a light form of the 

 shells from area 71 or 72. One of these three shells (pi. 7, fig. 26) 

 has the postembryonic whorls white, spirally lined with deep olive 

 buff; impressed sutural band amber brown, subsutural band ochra- 

 ceous tawny.
