The embryonic shell consists of 3 to 3J whorls, the first 1 or 

 If flesh-tinted, wide, indistinct dark stripes then appearing. 

 The last embryonic whorl has alternately snow-white and brown 

 stripes, very obliquely descending forwardly. The banded pat- 

 tern then begins. The lines and bands of brown are usually a 

 little serrate. The surface is glossy, with dense, weakly devel- 

 oped decurrent striae. Banding variable, as shown in the fig- 

 ures, in all the localities mentioned above. 



In a lot of 42 from Wailuku, 24 are sinistral. A lot of 32 

 from Wailee has 7 sinistral, all with broad bands. From La- 

 haina, in a lot of 60 shells, 34 are sinistral, patterns the same 

 as in the dextral shells. Specimens from Wailuku are figured,
