Pleurotoma is certainly feminine (from ir\evpbv and tout/), 



and not (as Philippi would have it) neuter. I was at first

noun of the first declension, and of the feminine gender, offend 



against the laws of grammar (Moll. Sic. ii. p. 165, footnote). 



Anatomia, apotome, and epifoma or epitome, formed from the 



same verb (rejuvw), are all feminine.
