 straight, truncate, terminating by a twisted plait passing within. 

 Long. .6, diam. .25 in. 



Remarks. This species is more cylindrical than any of its 

 congeners, resembling most A. remyi Newc, which is longer, not 

 umbilicate, more pointed at the apex, with a twisted, not truncate 

 columella. 



From venusta and citrina Mighels, it varies both in form and 

 color. With some varieties of picta it claims analogy onh^ in the 

 general plan of painting. Its striking characteristics are its blunt 

 apex, slightly rounded whorls, small aperture, short and white 

 columella, umbilicus, and general plan of coloring. 



Hab. A few specimens were coUedled at an elevation of 7500 

 feet on West Maui by the Rev. J. M. Alexander, to whom the species 

 is dedicated. — Newc. Puu Kukui. — Thaanum. Top of West
