 to yellow. In two cases the last three whorls are yellow. Suture 

 sometimes marked with a brown line ; columella purple, rarely 

 white ; 152 specimens. This color-variety is found on most of the 

 sub-ridges above and including sub-ridge XIV. Only a .single 

 specimen was found below sub-ridge XIV. 



Color-variety S. 



Shell white, apex and spire white, base just below the periph- 

 ery encircled by a dark brown band ; a light brown band encircles
