The embryonic whorls appear smooth, but under the micro- 

 scope they show an extremely minute, dense and irregular 

 roughness of pits and granules. On later whorls there is 

 some irregularly developed but very low striation between 

 and parallel to the riblets. In some fresh specimens the rib- 

 lets are unequal, inconspicuous or in part obsolete.
