 3,4. 



The shells are stouter than in Cinderella. The color of one 

 is uniform brown without bars and it has a lighter or yellow 

 tone along the shoulder of last volution, apex ashen (fig. 4). 

 The other shell has broad pearl-grey bands cut up by smaller 

 brown bands and a pearl-grey area around the columella 

 on the base. The preceding whorl is brown with light pearl- 

 grey shoulder, and apex ashen. These are the colors and 

 ornaments of A. pulla of Lanai, but the shell is distinct in 

 being a little stouter or more globose than in that species. 

 It is also wider than A. jolmsoni. There is no trace of an 

 'outer layer of cuticle. The apex is costate and carinated. 

 Length 11, diam. 6.3 mm. (fig. 3, type).
