“Genus Malmgreniella, new genus
Type Malmgreniella dicirra, new species
The body is long, linear, depressed; segments are variable, ranging from 41 to 56. Elytra number 15 pairs, are inserted as in Harmothoe to segment 32, and this region is followed by a posterior one with dorsal cirri instead of elytra. Palpi and dorsal cirri are smooth. Dorsal cirri are of two kinds; their appendages are either long and cirriform or short and proximally expanded. The prostomium is lepidonotoid, with the paired antennae inserted terminally but not continuous with the prostomium. The pelagic Drieschia Michaelsen also has alternating long slender and short thick dorsal cirri but in this genus the cirrophore, not the appendage, is inflated.”
