a half are three faint lines of cinnamon, base banded with four bands 

 of burnt umber. Length 17.3 mm., greater diameter 10.7 mm., spire 

 height 9.6 mm. An obese shell measures: Length 17.1 mm., greater 

 diameter 12.6 mm., spire height 9.2 mm. 



ACHATINELLA APEXFULVA BAKERI, new subspecies 

 Plate 3, Figure 30; Plate ii, Figures 20-20& 



The shell is small, the last whorl is usually yellow, and has a 

 characteristic yellow subperipheral band. The form is extinct today. 

 It probably came from an isolated lowland locality. No intermediates 

 have been located by me connecting it to any other race of A. apex- 

 fulva. The strongly axially streaked color pattern is similar to 

 A. a. apicata or A. a. wahiawa. The presence of the subperipheral 

 band may cause this form to be confused with A. a. gulickii. But 

 A. a. hakeri mainly differs from both forms in the yellow color pattern 

 of the last whorl. 



The embryonic whorls of the holotype (pi. 3, fig. 30) are light 

 ochraceous bufT ; first half postembryonic whorl vinaceous fawn 

 axially streaked with white, next half whorl pale drab gray axially 

 streaked with light brownish drab, last whorl and a half naples 

 yellow axially streaked with straight and zigzag streaks, speckled and 

 lined with mars brown, below the edge of the periphery a band of 

 naples yellow; impressed sutural band pale pinkish buff; lip and 

 columella callus tilleul buff. Length 16.4 mm., greater diameter 11. 5 

 mm., spire height 8.5 mm. The usual form was not determined because 

 of the paucity of specimens. 



Distribution, area?: Waimea, J. S. Emerson, BBM 102333, A. F. 

 Judd ex J. S. Emerson, BBM 162334. "Found on a Plateau north 

 of Waihalona [Kawaihalona?] Gulch below North Branch on pua 

 [Osmanthtis^ tree on a clump in open plain." (O. P. Emerson 

 collection, MCZ.) This form is named after Dr. H. B. Baker, of the 

 University of Pennsylvania. 



The shell may be narrower (pi. 11, fig. 20) and have a vivid 

 yellow ground ; the first postembryonic whorl brownish drab axially 

 streaked with white or pale drab gray, last two whorls yellow ocher 

 axially streaked with natal brown, just below the edge of the periphery 

 a band of yellow ocher. Length 18.2 mm., greater diameter 11.5 mm., 

 spire height 10.5 mm. 



A lighter color pattern and an obese shell (pi. 11, fig. 20a) has the 

 first half postembryonic whorl axially streaked with light cinnamon 

 drab and white, penultimate whorl pale pinkish cinnamon or white,
