tany, 20 metres. 
* Haeckel has described several of these before in^his Prodrom. System. Medus. 
1877, but in almost every case either the generic or specific name, or both, have 
been changed. The 83 new' genera contain 94 new and 59 known species. 14 
of the new genera are founded for 21 species, all previously known ; and consider- 
ing that the “ system ” will in all probability be very widely adopted, the Eecorder 
has thought it advisable, for purposes of reference, to give all the species for 
which new genera have been founded, with a complete synonymy.
