Family JULIIDAE E. A. Smith, 1885

Hemiplicatula – Deshayes, 1861: 128-129. — Type species (M): Placuna solida “Deshayes in Melleville, 1843”, that is, Placuna solida Melleville, 1843 . Semiplicatula P. Fischer, 1886 , is an unjustified emendation. — Current status: valid genus.

Prasina – Deshayes, 1863: 25-29. — Type species (M): Prasina borbonica Deshayes, 1863 . — Current status: synonym of Julia A. A. Gould, 1862 ( Pease, 1871: 102). Type genus of Prasinidae Stoliczka, 1871 , a synonym of Juliidae E. A. Smith, 1885, which is conserved by tradition, pending an application to the ICZN ( Bouchet et al. 2017: 358, 383). Juliidae would inherit precedence from 1871. E. Lamy (1928) had speculated as to the relationships of Deshayes’ genus.
