Specimens from Kobe, Setsu (B. Schmacker), are gray-brown 

 or [reddish-brown, worn, with 8J 10 whorls, and are about 13 mm. 

 long. The subcolumellar lamella emerges. 



Nohaia, Yamato. Specimens measure from 12.3 x 3.3 mm. with 

 9J whorls, to 14 x 3 mm. with 10 whorls. The subcolumellar 

 lamella emerges. 



Aiga, Kii. Glossy, orange-brown, transparent enough to show 

 the lunella and plicse through; whorls 9^-1 OJ; length 11J 

 13^ mm. Subcolumellar lamella emerging. 



Nachi, Kii (fig. 51). Brownish dark-red, opaque. Whorls 10 

 to 11 ; length 12 J to 14 mm. The subcolumellar lamella emerges 

 weakly or is immersed. 



Kurozu, Kii. Whorls 10, length 12^-13 mm. The subcolumel- 

 lar lamella emerges slightly or is immersed. 



Ikari, Awaji (fig. 50). Color and texture as in last. Whorls 

 10; length 13-14 mm. The subcolumellar lamella emerges. 



Suimura, Awa, Shikoku (figs. 52, 53). Rather light chestnut- 

 brown, some specimens showing the lunella and plicse through. 

 Length 12-15 mm. The subcolumellar lamella emerges. 



Obi, Huga. The shells are gray-brown or reddish-brown, and 

 measure 13 mm. long, 3 wide, with 10 whorls. The connection 

 between the superior and spiral lamellae is very low, almost inter- 

 rupted, and the lunella is somewhat arcuate. The subcolumellar 

 lamella emerges weakly. The clausilium of a specimen from this 

 locality is figured (fig. 54).

Smaller and somewhat more slender than C. aurantiaca, the sub- 

 columellar lamella immersed ; lip narrower ; lunella not quite reach- 

 ing the upper palatal plica. 



This small form is usually fairly distinguishable from the typical 

 aurantiaea. It extends from Harima to Yamato or Kii, specimens 

 being before me from the following localities : 



Tomisato, Kii. Whorls 8-9; length 10-11 \ mm. The sub- 

 columellar lamella barely emerges. It is not typical erberi. Per- 

 haps referable rather to aurantiaca proper.
