 specimens are reported by Mr. Frick to have come from 

 Ahuimanu (Gulick}. 



"This species is most nearly related to A. analoga Gk. which 

 is readily distinguished from this by the two black lines upon 

 the periphery of the whorl. The black or dark brown lines of 

 that species belong to the solid substance of the shell, while 

 the green and yellow bands of this species belong to the 

 epidermis. No dextral form of this shell has been found' 

 (Gulick}.
