Fig. 19

Scalpellum abyssicola Hoek 1883: 114, pl. VI, fig. 12; Stubbings, 1936: 20, fig. 8; Nilsson-Cantell, 1938: 7; Zevina, 1969: 67. Catherinium abyssicola: Zevina, 1981a: 251–252, fig. 187.

Material examined. Holotype NHM UK 2013.1096 and additional specimen NHM UK 2013.1097, Stn 24: Pacific, North West (Middle of); 3752 m.

Supplementary description. Zevina (1981a).

Distribution. Pacific, Northwest and Eastern Central; Indian Ocean, Western. Known depth range 2000 to 5540 m.

Remarks. The second specimen (Fig. 19B) was not listed or explicitly mentioned by Hoek (1883) in his original description of the species. The specimen is smaller, with the estimated capitulum length significantly less than the 8 mm stated by Hoek for the holotype. We, therefore, consider it to be additional material and not of paratype status.
