As to the specific name, Monterosato observed that long before 

 Philippi' s work, Lamarck had used it for another species (a Grignou 

 fossil) of the present genus ; but the figure (pi. 60, f. 9) in the 8th 

 volume of the ' Annates du Museum,' which Deshayes in his second 

 edition of the ' Histoire naturelle des auimaux sans vertebres,' refers 

 to the Auricula (acicula) of the 6th volume of the ' Aunales,' can 

 hardly be correct, because none of the other figures in the same 

 plate correspond with either the numbers or the brief descriptions 

 given by Lamarck in his list of species. Indeed, Deshayes says, as 

 to Auricula acicula, "II est tres-probable que cette espece n'est 

 point une Auricule, mais une Tornatelle allongee." The genus 

 Auricula of Lamarck was a heterogeneous assemblage of species, 

 and included Melampus, Actceon or Tornatella, Odostomia, Pyrami- 

 del/a, and Ringicula. The peculiar character of the Pyramidellidce, 

 viz. the sinistral nucleus, was not noticed by Lamarck or Deshayes.
