Phylogeny and origins of Enchytraeidaee analyses as evolutionary or phylogenetic groups. Five are substantiated as monophyletic: ., and .. In addition to most of the achaetine genera, . is shown to be in great need of revision. Its recognition is a continuing source of confusion to taxonomic resolution of Enchytraeidae.

Biological studies upon , Bouguenec & Giani 1987 in breeding culturesltures were carried out to determine the structure, density and biomass of the populations. A maximal density of 1396314 worms was recorded after 85 days of culture. Net production reached 21.48 g m. day. after 26 days in a culture initiated from cocoons.

Histophysiology of digestion and observations on the structure of the alimentary canal in the ectosyse activity appears in the intestinal margins during the alkaline phase of digestion. Scattered, pyramidal cells found only in the anterior intestine contain yellow refractile spheres. The spheres stain alcian blue pH 2.5 and bromophenol blue positive and exhibit a strong acid phosphatase activity a

The various enzymatic activities have been correlated with the ultrastructural data and a possible functional meaning of the different muscle layers has been proposed.
