Comments by Cossmann & Pissarro, 1909, p. 50:

  • “Remarks. - We have referred this species to the section Seraphs of the genus Terebellum, although we have not been able to study the details of the aperture, especially the anterior extremity. Should this anterior extremity terminate in a sharp rostrum instead of being truncated like that of Terebellum, this shell would belong rather to the genus Semiterebellum related to Hippochrene, which it recalls, indeed, by the posterior channel of the aperture. At any rate, d’Archiac and Haime’s Memoir does not contain any forms referable to T. lanceolatum which is characterised chiefly by its acuminate spire: T. obtusum J. de C. Sow., for instance, has it rounded and short.”
