four species included hitherto in the South African fauna and to 

 fix the systematic position of the only species described by Krauss 

 as new. The following is a list of Krauss' names with their 

 equivalents : 



Sphaeroma savignii = Dynamenella kraussi, n. sp. 



Sphaeroma macrocephala, Krss. == Dynamenella macrocephala (Krss.). 

 Sphaeroma perforata = Parisocladus stimpsoni (Heller), 



n. gen. 



Sphaeroma jurinii - Exosphaeroma gigas (Leach). 



Sphaeroma tristense = Exosphaeroma kraussi, Tattersall. 



With regard to the last Tattersall (1913) has already suggested 

 that Krauss' tristense was not Leach's tristense, and described it as 

 a new species. 



Dr. L. von Lorenz, Director of the k.k. naturh. Hofmuseum in 

 Vienna, has also very kindly transmitted for my examination the 

 Sphaeromids collected by the " Novara " expedition in 1857-9 and 

 described by Heller. As a result, my identification of S. scabricula, 

 Heller, and <S. stimpsoni, Heller, have been confirmed, as also the 

 specific identity of certain Cape specimens with the S. perforata of 

 Heller, and also in all probability with the S. perforata of M. 

 Edwards. A few of Heller's mistakes in regard to S. stimpsoni 

 and S. perforata, which have caused trouble to previous workers, 

 have been corrected. Hansen's opinion (1905) that S. Integra, 

 Heller, should be referred to Isocladus is shown to be correct, and 

 at the same time the specific distinctness of S. integra, Heller, and 

 S. tristense, Leach. 



In the genus Cymodoce the difficulty of assigning the females to 

 their respective males, especially when not taken in the same haul, 

 is a recognized drawback to correct classification. In the present 

 collection C. acanthiger, umbonata, and unguiculata, n. spp., are the 

 only species of which both sexes were taken in the same haul. In 

 the case of the others the specimens were found to group themselves 

 around certain localities ; males being taken in one haul in one place 

 and females in another haul not very far away. Where in such cases 

 the males and females show a close agreement in the details of the 

 appendages, I have considered it not too great an assumption to 

 regard those males and females as belonging to the same species, 

 e.g., C. valida, Stebb., africana, n. sp., and comans, n. sp. 



As far as present knowledge goes there seems to be little difference 

 between the faunas of Table Bay and False Bay. There is, however,
