Distribution (after Thandar 2008 ). Luderitz ( Namibia ) to Port Elizabeth ( South Africa ), 0– 110 m . Remarks. This is a well-known southern African endemic previously much confused with other congenerics but this controversy was cleared up by Cherbonnier (1952) and Thandar (1987) . Natasen Moodley (2000) , analysed the ossicles of several forms and this was summarised by Thandar (2008) . No brood pouches described for the species by Cherbonnier (1952) and Thandar (1991) were observed. A species of some contention is Cucumaria leonina var. africana described by Britten (1910) from Luderitz ( Namibia ) and assigned to the genus Pseudocnus by Panning (1949) . This species, never found again, was erroneously relegated to the synonymy of Pseudocnella insolens by H.L. Clark (1923) and this was reiterated by Deichmann (1948) , Cherbonnier (1952) and Thandar (1987 , 1991 ). It is here recommended that Panning’s (1962) re-description of Britten’s species as Pseudocnus dubiosus africanus , presumably from type material, must be upheld until a revision of the genus Pseudocnus , currently in progress, is completed.
