11. Contributions to the Crustacean Fauna of South Africa. By 

 K. H. BARNARD, M.A., Assistant. 



(Plates XV-XVII.) 

 No. 6. FURTHER ADDITIONS TO THE LIST OF MARINE ISOPODA. 



THE present report deals with 73 species, of which 45 are described as 

 new to science and 12 have not hitherto been recorded from South 

 African waters. 



The greater part of the material is derived from the rich collections 

 made by the Cape Government trawler s.s. " Pieter Faure." That the 

 material has not been available sooner is due to the fact that many 

 large bottles labelled " Varia to examine " had never been examined, 

 and consequently contained a mixed assortment of Sponges, Hydroids, 

 Alcyonaria, Polychaets, Crustacea, etc. 



Moreover, while going through the collection of sponges for the 

 purpose of extracting the spongicolous barnacles (Acasta and Balanus 

 spp.) many Isopods and Amphipods inhabiting galleries and burrows 

 in the sponges were brought to light. 



The Amphipods cannot be dealt with on this occasion, but so far as 

 the Isopods are concerned this paper may be regarded as a final report 

 on the " Pieter Faure " material preserved in the Museum. 



The fauna-list of South African marine Isopods now includes close 

 on 170 species, so far as recorded in the reports of Mr. Stebbing and 

 myself, including the present paper. But that this is not a complete 

 list of the fauna is shown by the fact that the German South Polar 

 Expedition,* during its very brief stay in these waters, captured the 

 following 5 additional new species : . 



Heterotanais (?) capensis. 



Eurydice natalensis. 



Astacilla setosa. 



Antias uncinatue. 



Microniecus ornatus. 



Moreover, it is probable that the list will be further increased when 

 the report on the Isopods collected by the German Deep-sea Expedition 

 is published. For in other groups of marine animals the " Valdivia " 

 collected material of great importance for the study of the South 

 African fauna. Other reports dealing with the Isopodan fauna, which 

 may be expected to follow, are those on the collections of Dr. L. 

 Schultze and Dr. W. Michaelsen.
