General Catalogue of South African Crustacea. 571 



species all from the Cape of Good Hope ; one lot was collected 

 by Dr. Krauss, at Algoa Bay, and I strongly suspect is the 

 species described by him in his ' Siidafrikanischen Mollusken' 

 as Conia porosa." Asemus porosus is the name used by 

 Krauss. 



1848. Asemus porosus Banzani, Krauss, Die Siidafrikanischen Mollus- 

 ken, p. 136. 

 From Algoa Bay. 

 1897. Tetmclita serrata, Weltner, Arch. Naturg., vol. Ixiii., pt. 1, 



p. 258. 



Weltner reports it from Port Grosvenor, in Pondo Land, 

 South Africa, as found by Bachmann, "in great numbers on 

 ledges of rock, bare at ebb-tide, especially on places where the 

 surf splashes violently." 



TETBACLITA EOSEA (Krauss).

Darwin says : '' I am greatly indebted to Professor Krauss 

 for having sent me, for examination, the unique specimen 

 collected by himself in Algoa Bay. There can be no doubt 

 of the identity of the African and Australian specimens. It is 

 a singular circumstance that the same species should occur 

 in these two distant places, and, as far as at present known, 

 not in the intermediate, more tropical coasts."
