the continental Australian Goniocidarls Jlorigera, and perhaps of the Southern Ocean 

 Porocidaris elegans. 



WhUe of the abyssal species common to the Atlantic and Pacific we have Salenia 

 hastigera, Aspidodiadema tonsum, Aerope rostrata, Periaster limicola, and Aceste 

 bellidifera. 



As strictly Pacific representative abyssal species we can enumerate Asthenosoma 

 coriaceum, Phormosoma tenue, Phormosoma luculentiim, PJiormosoma hursaria, Trigono- 

 cidaris monilini, Prionechinus sagittiger, Pcdeotropus loveni, Pourtalesia laguncula, 

 Pourtalesia rosea, Homolampas fidva, Cionobrissus revinctus, and ArgojKitagits vitreus, 

 the Southern Ocean species extending only into the southern part of the Pacific, as in the

 than we find going northward in the Atlantic.
