Astrothamnus Matsumoto, 1915

Astrothamnus benhami (Bell)

• Astrotoma benhami. Mortensen, Th., 1924. Vid. Medd. dansk naturh. For., 77, p. 104–6, Pl. IV (6–7).

Material Examined: None.

This species is still known only from the original type material taken in 300 fathoms off North Cape, by the Terra Nova. The presence of 3 or more secondary teeth on the girdle hooklets, and thorny granules scattered among the disc granules, indicates that the species should be transferred to Astrothamnus.
