Record of the occurrence in Australia of Ligia exotica Raux (Crustacea, Isopoda, Oniscoidea)

In all but one instance, examples of genus Ligia Fabricius reDorded from AustraUato date have been assigned to L. australiensis Dana, 1853. The one exception is a record by Jackson (1922, p. 697) of L. novae-zealandiae Dana, 1853, from Sunday Island, Victoria. Specimens of Ligia from Bobbin Head, New South Wales, which were presented to me by Dr. J. Ie Gay Brereton, differ from both of these species. A comparison of their characters with the descriptions of L. exotica Raux, 1828, given by Chilton (1916, p. 462), Jackson (1922, p. (93) and Verhoefi' (1928, p. 116) shows that they should be assigned to L. exotica.
