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.
