The maximum lengths of the specimens (60 mm) and ossicles (150 µ m) (from Théel 1886, Pawson, 1971, Rowe & Clark 1975) support the recognition by Théel (1886) of this variety.

In discussing the holothuroids of Marion I., Rowe (in Rowe & Clark 1975) affirmed the Ekman (1927) synonymy of Cucumaria serrata var. marionensis with Pseudocnus laevigatus . Rowe reported the largest specimen as 60 mm long (55 mm in Théel 1886), and largest pear shaped ossicles as 150 µ m long (same as Théel 1886). The material examined by Pawson and Rowe appears to be conspecific with Theel’s variety. These sizes are significantly smaller than for the Kerguelen specimens of P. laevigatus (130 mm, 200 µ m) and P. intermedia (80 mm, 176 µ m) discussed above. While recognizing the Théel variety I do not reject the possibility that Pseudocnus laevigatus also occurs on the Marion Is, as both P. laevigatus and P. intermedia both occur on the Kerguelen Is.
