. Text-fig. 8. Tomopteris septentrionalis: parapodia of specimens from (a) St. 250, (b) St. 2017. Discussion. The diffuse chromophil gland in T. septentrionalis might cause it to be confused with both T. planktonis and T. elegans. T. planktonis however has a compact chromophil gland in the adult and it is only in young specimens that any similarity between the two exists; as noted above (p. 174) Monro's (1936) specimen of T. septentrionalis from St. 41 A, is T. planktonis. The presence of the first pair of chaetigers in T. elegans serves to separate it from T. septentrionalis. General distribu
