Echinolampas (Palaeolampas) crassa: Clark & Courtman-Stock, 1976: 244   .

Material examined. A22340; MBC-A 022340; MBC-A 022341; MBC-A023373; MBC-A077887; MBC- A077885; MBC-A077886; A22267; A22268; A22272; A22270; A23433; A22292.

Identification. Test moderate to large, aborally raised, and slightly elongated. Apical disc anteriorly positioned, monobasal, with four gonopores. Peristome wider than long, sub-centrally positioned; bourrelets and phyllodes distinct; five well-developed petals, extending to edge, distally opened; anterior-lateral petals being the shortest, sub-equal. Posterior interambulacrum sometimes having a naked space, not raised towards peristome, tuberculation and spines dense, uniform, and becoming sparse towards peristomial area. Test and spine both brown.

Global maximum size. Maximum test length 125 mm.

Global distribution. Endemic to South coast of South Africa, at 15–500 m depth ( Döderlein 1910; Clark & Courtman-Stock 1976).

Remarks. The most stricking feature that distinguishes Echinolampas crassa   and Tropholampas loveni   , is the lack of obvious sexual dimorphism in Echinolampas crassa   .
