These specimens seem to me to be indistinguishable from a rather small example of the uncommon deep water European species. Augener and Fauvel give the length as between 60 and 150 mm.

These specimens seem to me to be indistinguishable from a rather small example of the uncommon deep water European species. Augener and Fauvel give the length as between 60 and 150 mm. Fauvel gives the number of gill filaments in a fully developed branchia as between 8 and 17, and Augener as between 10 and 22. In these specimens 8-15 is the maximum. Fauvel states that the gills cease between the 30th and 46th segments and Augener about the 60th segment. In these specimens they usually cease between the 40th and 45th segments. This species is closely related to E. atlantica, Kinberg. Ehlers (1901, p. 125) gives an account of a small example of the latter species mea- suring 41 mm. long and with 124 chaetigers. In this the median tentacle reaches back to the 9th segment (7th chaetiger) and the first and second segments are together equal.
