Shells from Leilehua are quite large, of a uniform dingy 

 straw-color, hardly shining, with a much thickened lip and 

 having a costiform callus connecting the margins of the aper- 

 ture. Those from Haleauau are very glossy, pinkish brown 

 at the base, darker at the periphery, the spire and upper 

 portion of the last whorl are almost white and the callosity 

 of the outer lip is hardly developed. Those from Palehua 

 have a dark plumbeous (sometimes with a reddish tinge) 

 base, with the spire and upper portion of the last whorl of a 

 rusty straw-color.
