188 HELIOIDJE. 



while the lower portion is ornamented with a broad dark brown 

 band below the peripheral white girdle and a narrow one around 

 the umbilicus. Another specimen is almost unicolorous white 

 with a narrow brown band around the umbilicus. The original 

 habitat — Tranquebar — recorded by Chemnitz, I consider extremely 

 doubtful. It is a well known fact that formerly less importance 

 was attached to locality than is the case at the present day.

 slightly expanded, columellar margin dilated and reflexed over the 

 narrow perforation of the umbilicus.
