In embryonic shells of 3% whorls, length 5 to 5.6 mm., 

 the first whorl is flesh-colored, the rest pale-yellow. The first 

 whorl is glossy and shows very fine, weak growth-striae. On 

 the next whorl the striae become strong and arcuate ; and on

 striae. The periphery at this and earlier stages is angular 

 and the base nearly smooth. Axis is narrowly perforate.
