with from one to three bands of orange, yellow, fulvous ^r 

 white. The marginal groove to the suture is very close and 

 distinct in all. The golden yellow variety is without 'bands. 

 In all the colors are remarkably rich and vivid" (Swainson).

This species differs from byronii chiefly by its smooth sur- 

 face. The last whorl is more evenly rounded, -while in byronii 

 it is often subangular. The pattern of Swainson's left-hand 

 figure was selected by Pfeiffer as typical. It is shown in our 

 pi. 27, fig. 5c ; also pi. 31, fig. 13. There are two broad chest- 

 nut zones on a yellow ground. This happens to be a rather 

 rare color-form which however occurs in Gulick 's Wahiawa 1 

 series (fig. 5c) , and has been collected by Mr. Spalding on the 

 eastern spurs of Kawaihalona (pi. 31, fig. 13). I take the 

 latter valley as type locality, since it was certainly from shells 

 taken in that neighborhood that Lord Byron's lei of Achat- 

 inellas was made. The lip is obtuse, black-brown, with a 

 whitish rib within. The glossy surface has exactly the char- 

 acter of that of nympha, etc. All of the large series examined 

 are dextral. Color-forms of a lot from Wahiawa (Gulick), 

 are as follows.

 ground ; sutural line usually chestnut.
