In the family Lycoridea, only 5 genera are recognized by Grube (8) : 
Lycastis, Sav., Nereis, L., Ceratocephala, Mgr., Tylorrkynchus, Gr., and 
Dendronereis, Pet. {Micronereis, Clap., is added, op. cit. 1874, pp. 79-80). 
The. genus Nereis is subdivided after characters offered chiefly by the 
paraguatha as follows : — Leptonereis, Kb. [^Nicon, Nicomedes\ Leon- 
nates, Kb., Ceratonereis, Kb., Platynereis, Kb. [^=Leontis, Pisenoe^, 
Lycoris, Sav. [= Nereis, Nereilepas, Cirronereis, Thoosa, NeantJies, Kb., 
Alitta, Hediste, Praxilhea, Mgn., Mastigonereis, Schm.], and Perinereis, 
Kb. [= Lipephile, Mgn., Arete, Pseudonereis, Paranereis, Perinereis, 
Nanmackius, Kb.]. All genera based upon a Nereilepas-, or a Iletero- 
tiereis-Bia.iQ, e.g., Eanereis, Ilcdyle, IpTiinereis, Heteronereis, Nossis, are 
of course rejected.
