Yar. polyactina, nov. var. PI. xv., figs. 1, 2. 



This is a colour variety. It has the shape of A. calamus, 

 C. and F., though sometimes narrower in front, and has the 

 fine radial sculpture. It may reach 21 mm. long by 17 mm. 

 broad and 7 mm. high, but it has brown rays gradually widen- 

 ing, generally seven, the odd one in the posterior centre ; but 

 there may be six, or as many as fourteen, by secondary inter- 

 calation. They may be broken up into blotches or specks, and 

 may tend to be united by reticulating spots and lines. The 

 shell is sometimes polyangulate as well as rayed. They grade 

 into typical A. calamus, Crosse and Fischer.
