The stratigraphic bias against placing Fontannesia in the Grammoceratinae should be eliminated. Certainly the affiliation through descent of Fontarwesia with Grammoceras s-l. can not seriously be doubted while the evo- lution of Sonninia from Hammatoceratidae is generally accept- ed. Thus, the Sonniniidae if retained as understood in the Treatise would be polyphyletic at the family level. Comparison. — The species shows a similar wide range of ap-.
