Pleurotoma is certainly feminine (from TrXevpbv and Tuj^r)), 



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



misled by his statmg that those who make Pleurotoma a 



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



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



A7iatomia, a'potome^ and epitoma or epitome, formed from the 



same verb (re/ivw), are all feminine.
