“Milnesium tardigradum DOYÈRE, 1840 (fig. 33)

Length 310-880 µm. Specimens from King George Island are typical (comp. RAMAZZOTTI, 1972; PILATO, 1973), those from Antarctic Continent belong to the form (or geographic race—according to MARCUS, 1936) having variable middle branch of claw. That branch is single in typical specimens (fig. 33e), in mentioned form it is divided into 2-5 teeth, mostly 3-4 (fig. 33a-d); one specimen even had it reduced (fig. 33a). A number of teeth is different within this species, often even on one leg (fig. 33a-c). The form is widely distributed; from Antarctic Continent recorded by SUDZUKI (1964).

Localities. Typical specimens: King George Island—13(1), 19(4). The form: Enderby Land—2(9).

A cosmopolitan species.”
