I have retained conuloides as a variety of zizyphinus, rather than 

 a species. It will he noted that zizyphinus from the Mediterranean 

 has a spirally sulcate form (var. cingulata\ and conuloides from 

 northern Europe has a smooth one (var. /wrigata). The latest treat- 

 ment of the species is in Bull. Soc. Mai. Ital. xiv, p. 77, 1889, article 

 by Monterosato. He splits the zizyphinus into live species !
