Distrih. Mediterranean (Dohrn, Sars) ; on the Atlantic 

 coast it has been procured by Chevreux (fide Dollfus) from 

 Brittany to Senegal and Teneriffe. Harger has found it on 

 the N.E. coast of America. Kroyer's types were from 

 Brazil, and Dollfus has rejected his name on account chiefly 

 of the distance of that locality ; but the range of the species 

 is known to be very extensive, and until the Brazilian 

 form is proved to be something different it is surely preferable 

 to retain Kroyer's name.
