ACHATINELLA APEXFULVA BRUNEOLA, new subspecies 



Plate i, Figure 32; Plate 5, Figures 17-17& 



Achaiinella turgida ovum Pfeiffer, Pilsbry and Cooke, Man. Conch., vol. 22, 

 p. 298, pi. 56, fig. 8a (only), 1914. 



The shell resembles A. a. ovum in form, but differs in having a 

 brown color pattern. Embryonic whorls of the holotype (pi. i, fig. 32) 

 white ; first half postembryonic whorl shades from white to ochraceous 

 tawny, penultimate and last whorl sudan brown, at the periphery and 

 below the periphery of the last whorl the ground is argus brown, 

 lined and banded with apricot yellow; Hp verona brown; columella 

 callus tilluel buff. Length 19.0 mm., greater diameter 13.0 mm., spire 

 height 9.7 mm., number of whorls 6^. 



Distribution, area 28: Kalauao-Hanaiki Ridge, type locaHty 182, 

 elevation 1,300-1,367 feet, Meinecke, 1926, 3 dextral 1929, 2 dextral 

 1933 (figs. 4, 4a, p. 53). 



The holotype has the usual form of the shell, and a color pattern 

 which occurs on 33 percent of the shells. An elongate shell (pi. 5, 

 fig. 17) has the usual color pattern on 58 percent of the shells; post- 

 embryonic whorls ochraceous tawny spirally banded with russet, 

 below the periphery of the last whorl prout's brown with a few lines 

 of yellow ochre ; lip and columella callus mars browai. Length 19.3 

 mm., greater diameter 12.2 mm., spire height 10.7 mm. A squat 

 specimen (pi. 5, fig. 17a), with a similar color pattern to figure 17, 

 has a very concave spire and inflated last whorl ; the postembryonic 

 whorls are profusely lined with russet. Length 19.0 mm., greater 

 diameter 13.4 mm., spire height 8.9 mm. The lightest color pattern 

 found on a single specimen (pi. 5, fig. 17&) has the first two post- 

 embryonic whorls pale ochraceous buff and lined with wood brown 

 darkening to fawn color, last whorl above the periphery pale ochra- 

 ceous buff lined with natal brown and buffy brown, at and below the 

 periphery the ground is chamois above and within the aperture, the 

 remainder of the whorl is cartridge buff; lip and columella callus 

 army brown streaked with white.
