The shell may have a lighter color pattern (pi. ii, fig. 34) ; embry-

 pale gull gray and banded with a central band of mars brown in the 

 center of which is a black line, a lower band just above the periphery 

 bone brown, divides into two lines on the last half of the penultimate, 

 the ground on the last half of the penultimate is faintly shaded with 

 mustard yellow, last whorl mustard yellow, banded above, below, and 

 at the periphery with a band of bone brown at the lower edge of 

 which is a band of mikado brown, just above the edge of the periphery 

 are two lines, an upper of mikado brown, and a lower of bone brown, 

 both of which fade to a lighter tint on the last half whorl; the im- 

 pressed sutural band darkens from mikado brown on the first whorl 

 to warm sepia on the last whorl. Length 18.5 mm., greater diameter 

 12.6 mm., spire height 9.5 mm. 



ACHATINELLA APEXFULVA WAILELENSIS, new subspecies 

 Plate 3, Figure 36; Plate ii, Figure 35 



The shell is not closely related to any of the known forms of 

 A. apexfiilva. The locality occurs far away from all the known 

 localities of A. apexfiilva and no intermediates between wailclensis 

 and any other form are known. The shell, however, has the usual form 

 of A. apexfiilva and resembles A. a. rpseata of Waimano Stream. The 

 liolotype (pi. 3, fig. 36) has the embryonic whorls white; first post- 

 embryonic whorl fawn color, last two whorls vinaceous fawn ; im- 

 pressed sutural band pinkish buff ; lip pinkish buff', columella callus 

 white. Length 17.3 mm., greater diameter 12.0 mm., spire height 

 10.3 mm., number of whorls 6. 



Distribution, area, 117: Wailele Gulch, locality 529-1, elevation 

 20 feet, collected by Mr. and Mrs. G. W. Russ, and Welch 1933. The 

 shells are found in a fossil state in a stone outcropping near the 

 Kamehameha highway (fig. 7, p. 194). 



An obese form of the shell (pi. 11, fig. 35) measures: Length 17. i 

 mm., greater diameter 11.9 mm., spire height 8.7 mm. ; postembryonic 

 whorls shell pink axially streaked with buff pink. A narrow specimen 

 measures: Length 17.6 mm., greater diameter 11. 2 mm., spire height 

 9.4 mm.
