pattern between A. a. ovum and .1. a. ruhidipicta. The shells prob- 

 ably came from above area 19 on the Manaiki-Moanalua Ridge. 



The usual form of the shell and the color pattern of 52 percent 

 of the specimens (pi. 5, fig. 4) has the postembryonic whorls white, 

 lined with cinnamon and mikado brown, and banded with chocolate, 

 last whorl subperipheral band white, below which is a line of cinnamon 

 and cinnamon buff, base chocolate ; impressed sutural band cinnamon ; 

 lip and columella callus light vinaceous fawn. Length 19.6 mm., 

 greater diameter 13.0 mm., spire height 9.8 mm., number of 

 whorls 6i. 



An elongate shell (pi. 5, fig. 4a) measures: Length 19.3 mm., 

 greater diameter 12.5 mm., spire height 9.5 mm.; last two postem- 

 bryonic whorls pale pinkish bufif, profusely lined and banded with 

 russet and mars brown, impressed sutural band cinnamon. An obese 

 form of the shell (pi. 5, fig. 4&) with light color pattern found on 

 31 percent of the shells has the postembryonic whorls white, lined with 

 pinkish buff ; impressed sutural band pinkish buff ; last whorl banded 

 at the edge of the periphery with a band and below the periphery 

 with bands and lines of chocolate. Length 19. i mm., greater diameter 

 13.4 mm., spire height 9.1 mm. 



Seven percent have a lined spiral pattern (pi. 5, fig. 4c) ; post- 

 embryonic whorls above the periphery lined with russet, peripheral 

 band narrow, about 0.5 mm. instead of nearly 2 mm. as in figure 4, 

 banded below and at the periphery with chocolate. The darkest 

 pattern (pi. 5, fig. ^d) on 9 percent, is russet, streaked with cinnamon 

 bufif on the first half of the penultimate, last half of penultimate ochra- 

 ceous tawny axially streaked with burnt umber, last whorl chocolate, 

 axially streaked with ochraceous tawny. A single specimen (pi. 5, 

 fig. 4^) has a white ground lined with warm buff; impressed sutural 

 band ochraceous tawny fading to white on the last whorl. This 

 pattern is very similar to lined patterns of ^. a. alhofasciata.
