Description. See Whitfield and Mackenzie (2011). The material examined matches the description well, and we make the following additions: Psolus salottii Whitfield and Mackenzie, 2011 , up to 71 mm length ( NIWA 40355), 54 mm wide, 29 mm high. Oral valves large and inconsistent in shape, ranging from rectangular with blunt ends to approximately triangular with pointed tips. Valves usually 10; always greater than 5.

Colour. Preserved: white.

Distribution. South Australia, Macquarie Ridge (Whitfield and Mackenzie, 2011) and this paper, 400– 600 m.

Remarks. The original description was based on one holotype specimen from southern Australia and four paratypes from Macquarie Island. We found an additional 46 specimens, confirming and extending the Whitfield and Mackenzie (2011) description. The dome-like lumps on the dorsolateral scales are not always visible, and they may only be on a few scales. The multilayered ossicles in the preparation are always distinctly dome-like and provide a useful diagnostic character for this species.
