The shape of the usual form and color pattern (pi. 12, fig. 22) 

 of the shell on the Kawaihalona-Opaeula Ridge or the Helemano- 

 Opaeula Ridge is more elongate and the color pattern darker. The 

 embryonic whorls are ochraceous buff ; postembryonic whorls vina- 

 ceous pink axially streaked and faintly spirally banded with benzo

Li the lot collected at locality 334 in 1932 by Meinecke a few 

 narrow yellowish-brown shells (pi. I2, fig. 22^) are found. This 

 pattern possibly belongs to a lower race, but until more is known 

 about this color form it will be considered to be A. a. paalacnsis var. i. 

 The embryonic whorls are ochraceous buff; postembryonic whorls 

 light pinkish cinnamon axially streaked with light drab, and drab on 

 the first two whorls, last whorl axially streaked with saccardo's umber

 of white or a dilute tint of pale pinkish buff, below the periphery of 

 the last whorl a line of snuff brown ; lip and columella callus light
