Abstract / Notes
The author compares morphologically forms of the rhabdocoel species Dalyellia sibirica (Plotn.) from various authors collected in Siberia, Russia, and Finland with those found by himself near Warsaw. His observations on Dalyella rossi Graff, D. fairchildi Graff, and D. nanella Bekl. are compared with related forms from N. America and Europe. Further details with plates are given for 3 marine forms, D. picta, D. panicilla, and D. scoparia. The descriptions of Castrada hofmanni and Castradella granea are further amplified and a new species, Castrada variodentata, is described.
