156 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. IO3 



Plate II, figure i6, is a color pattern similar to plate ii, figure 15, 

 except that it is banded on the last whorl above and below the 

 periphery with a band of pale ochraceous bufif which is the ground 

 color. The shell may have a zigzag pattern (pi. 11, fig. i6a), the 

 postembryonic whorl hay's brown or sorghum brown, axially streaked 

 with straight or zigzag streaks of pale mouse gray. An extreme 

 narrow shell (pi. 11, fig. 166) with a more marked zigzag pattern 

 measures: Length 19.0 mm., greater diameter 11.9 mm., spire height 

 10.6 mm. ; postembryonic whorls warm blackish brown, axially 

 streaked with zigzag lines of warm buff. Another specimen (pi. 11, 

 fig. i6c) shows another form of a narrow shell with a flattened base ; 

 postembryonic whorls chestnut faintly axially streaked or splotched 

 with warm buff ; impressed sutural band warm buff. Length 18.8 mm., 

 greater diameter 12.0 mm., spire height 10.6 mm. 



But by far the most unusual pattern, with the exception of patterns 

 i6b and i6c, is the shell of plate 11, figure 16c?. The embryonic 

 whorls are a deep shade of ochraceous buff; postembryonic whorls 

 fawn color sparsely axially streaked with pale ochraceous buff; 

 impressed sutural band fawn color. This color pattern may be a 

 pure race somewhere, possibly in the North Helemano or the South 

 Helemano at a low elevation below area 95. It looks very much like 

 typical A. a. apicata. 



ACHATINELLA APEXFULVA PAALAENSIS, new subspecies 

 Plate 3, Figure 21 ; Plate 12, Figure 20 



The shell is related to A. a. apicata var. i but differs in having a 

 blue-gray color pattern instead of a brown one. The holotype (pi. 3, 

 fig. 21) has the embryonic whorls ochraceous tawny; first half post- 

 embryonic whorl mikado brown axially streaked with white, remaining 

 whorls white axially streaked with light gull gray, and light neutral 

 gray; impressed sutural band the color of the ground, except on 

 the last half whorl where it is shaded with cinnamon drab; lip and 

 columella callus light vinaceous fawn. Length 18. i mm., greater 

 diameter 12.1 mm., spire height 9.7 mm., number of whorls 6 + . 



Distribution, area 106: North-South Helemano Ridge, type 

 locality 313-3, elevation 1,600-1,700 feet, 1933; South Helemano 

 Stream, locality 301c, elevation 1,350-1,400 feet, 4 dextral, Meinecke, 

 1933 (figs. 5, 5a, p. 105). 



The color pattern in area 106 may be darker (pi. 12, fig. 20) and 

 the form narrower than the holotype; last two and a half post- 

 embryonic whorls pale gull gray axially streaked with deep mouse
