Psolicrux coatsi ( Vaney, 1908)

Figure 2 d; table 1.

Remarks. Ekman (1925) synonymised Cucumaria aspera Vaney, 1908 with Psolidium (Cucumaria) coatsi Vaney, 1908 . This synonymy was not recognized in the Psolicrux coatsi ( Vaney, 1908) synonymy in O’Loughlin (2002). That omission is supported in this work. The small type specimen (11 mm long) of Cucumaria aspera Vaney, 1908 belongs as an additional species in the “ Cucumaria georgiana ( Lampert, 1886) group” created by Gutt (1988) and adopted by Massin (1992), based on the following characters described by Vaney (1908): tube feet confined to radial series; eight and two small ventral tentacles; irregular perforated plate ossicles, with some knobs.

Cucumaria conspicua Vaney, 1908 is removed from the Psolidium (Cucumaria) coatsi Vaney, 1908 synonymy by O’Loughlin (2002), and referred above to Cucamba psolidiformis ( Vaney, 1908) .
