The genera of this division stand greatly in need of 

 revision. Since Malmgren's publication in 1865 of his 

 valuable Nordiska Hafs-Annulater, with the erection 

 therein made of many new genera, there has been great 

 confusion and changing of boundaries. Indeed when a new 

 species turned up, it was almost certain not to fit with any 

 of Malmgren's narrow generic definitions, and consequently 

 had to have a brand new genus formed for its special 

 reception. In my belief, Malmgren, misled by his great 

 capacity for perceiving minute differences, attached too 

 much generic value to what were often altogether second- 

 ary divergences — the result being that he erected a host 

 of needless new genera. To this class, I am of opinion, 

 belong the genera Lagisca, Harmothoe, Evarne, and 

 Lcenilla. All are characterized by the possession of 15 

 pairs of elytra, stout notopodial setae, and bidentate apex 

 to the setae of the neuropodium. J These I have placed

J As Moquiu-Tandon remarks (Claus " Traite de Znnlogie"), great con- 

 fusion reigns in the nomenclature of the appendages of Polychsetes, and as a 

 guide I now apppend the following list of synomyms : — 



Huxley. M'Intosh & Malmgren. Grube. 



Parapodium = Foot 



Neuropodium = Ventral branch of the foot 



Xotopodium = Dorsal Branch of the foot 



Prsestomial tentacle = Tentacle = Unpaired tentacle 



Superior preestomial cirri = Antennae = Middle tentacles 



Inferior ,, ,, = Palpi = Lateral ,, 



Peristomial cirri = Tentacular cirri = Tentacular cirri
