The ancient naturalists had some strange notions as to 

 the sexes of the Mollusca. Aristotle, as is well known, 

 believed in their spontaneous generation ; but a different

 vagina as the female of the same species. The reasons 

 which they gave for this distinction were not altogether 

 uncomplimentary to the fair sex, consisting in S. vagina 

 being (although smaller) of a uniform complexion, and
