Family ASCAMPBELLIELLIDAE Corliss, 1960

For	Craterellidae

Lorica cup-shaped, not elongate, with smooth to denticulate oral rim; one or two collars; some species with agglutinated coccoliths; all forms marine (mainly eupelagic); no fossil species.

[I am indebted to Mme. Laval-Peuto (personal communication) for suggestions that this family be split off from the (former) Petalotrichidae and that Petalotricha is confamilial with Cyttarocylis (with Cyttarocylididae having priority over Petalotrichidae): see preceding family.]
