3. ADDITIONS TO THE MARINE ISOPODA, WITH NOTES ON SOME 

 PREVIOUSLY INCOMPLETELY KNOWN SPECIES. 



(Plates XXVII.-XXXVIII.) 



THE following paper is the result of the examination of a large 

 quantity of Marine Isopods collected at various times partly by the 

 Cape Government trawler s.s. " Pieter Faure " and partly by 

 members of the staff of the South African Museum. It contains 

 descriptions of 8 new genera, 42 new species, and one new variety. 



These numbers, though somewhat surprising, are but evidence of 

 the richness of the South African crustacean fauna : a fauna which 

 has only in recent years been systematically explored. Even so it 

 is safe to say that only the fringe has been touched, and that there 

 is still much to be done, especially as regards the minuter forms. 

 Of the latter, those described in the following pages come exclusively 

 from the littoral region of Table Bay and False Bay. With the 

 exception of these two localities and the Natal coast the littoral 

 region has been scarcely examined, even superficially. As an 

 example of the results of older methods of collecting, it may be 

 mentioned that Krauss, the pioneer of South African Carcinology, 

 obtained only 19 specimens of Sphaeromids from Table Bay and 

 the Natal coast. 



The remaining 25 species consist of species either hitherto 

 incompletely known or not recorded from South African waters. 



Through the kindness of Dr. Lampert, Director of the Stuttgart 

 Museum, I have been permitted to examine the specimens of 

 Sphaeromids collected by Krauss in 1838-42. The specimens have 

 been preserved dry, but otherwise they are in excellent condition 

 and leave no doubt as to their identity with the fresh spirit specimens 

 at my disposal. The result of this examination has been to exclude
