The Crustacea referred to in this short paper were collected 

 by Professor F. Wood Jones, of Adelaide University, in an 

 expedition made towards the end of 1920 to the Investigator 

 Group and the Nuyt's Archipelago, lying to the west of Eyre- 

 Peninsula, South Australia. The whole of the species here 

 mentioned were, however, obtained at the Nuyt's Archipelago, 

 most of them in Smoky Bay. They are all referred to species 

 already known, though in some cases they have not been 

 hitherto recorded from South Australia. , 



In addition to these species numerous specimens of 

 terrestrial Isopods, belonging to Cuhoris and allied genera, 

 were collected from several localities. These have been sent 

 for determination to Dr. W. E. Collinge, York Museum, 

 England. Several shore Amphipoda fOrcliestia, etc.) were 

 obtained at various places, but they are all too immature for 

 determination. 



AMPHIPODA. 

 Leucothoe spinicarpa (Abildg.). 



Leiicothoe spinicarpa and L. miersi, Stebbing, 1906, p. 165. 



Leucothoe comni en sails, L. dicmenensis, and L. gracilis. 

 Stebbing, 1910, p. 636. 



Leucothoe spinicarpa, Chilton, 1912. p. 478, and 1921, p. 59; 

 Barnard, 1916, p. 148. 



Locality. — Smoky Bay, South Australia, 3*5 to 4 fms. 

 Two specimens; length, 10 mm. 



In my report on the Amphipoda collected by the F.I.S. 

 "Endeavour," I have given reasons for considering all the 

 forms mentioned above as belonging to the cosmopolitan 

 species, L. spinicarpa (Abildg.). The species seems to be com- 

 mon at numerous places on the Australian coasts. Barnard 

 has given some further particulars of specimens from South 

 Africa, and has added L. miersi^ Stebbing, to the list of 

 synonyms, as I had already done in my MS. notes.
