To these 12 species must be added Dytastcr exilis, the type form of which was taken 

 in the South Pacific and the variety gracilis in the South Atlantic. 



Turning now our attention to the genera represented at these twenty-nine Stations 

 in the Southern Hemisphere, we find that out of the total number (182) 19 genera (or 

 1 per cent. ) are known up to the present time only from these Stations. 



LIST II I. 



We give here a list of these 19 genera, the great majority of which include only a 

 single species taken each at a single Station, but two of the genera (Ophiodiscus and 

 Parelpidia) each contain 2 species, each species being represented at a distinct Station. 



Axoniderma. 



Caulocalyx. 



Hyalostylus. 



Trachycaulus. 



Aulorchis. 



Ophiodiscus. 



Polyopis. 



Polystomidium. 



Nauphanta. 



Tesserantha. 



Pythonaster. 



Ophiotholia. 



Enypniastes. 



Parelpidia. 



Samythopsis. 



Crossophorus. 



Camaclw. 



Tylaspis. 



Histiopsis. 



To these 19 genera may be added the genus Acanthomunna with a single species, 

 which was taken at two neighbouring Stations near New Zealand, one of them being, 

 however, under 1000 fathoms (viz., Stations 168 and 169, 1100 and 700 fathoms).
