LIST li. 



Turning now our attention for a moment to the genera represented at these eight 

 Stations in the Southern Indian Ocean, we find that out of the total number of genera 

 (186) 30 genera (or 16 per cent.) are known up to the present time only from the region 

 under consideration. We give here a list of these 30 genera, from which it will be 

 observed that the great majority include only a single species, there being in fact only 

 2 genera (Ophioplinthus and Abyssascidia) each containing 2 species, and that the 

 great majority occur at a single Station ; 3 of the genera, were, however, represented 

 each at two Stations, while 1 genus (Grubianella) was found at three Stations. 



Meliiderma (contains 1 species taken at a single Station). 

 Balanella (contains 1 species taken at a single Station). 

 Pleorhahdus (contains 1 species taken at a single Station). 

 Callozostron (contains 1 species taken at a single Station). 

 Tealidium (contains 1 species taken at a single Station). 

 Halisiphonia (contains 1 species taken at a single Station). 

 Pedis (contains 1 species taken at a single Station). 

 Periphema (contains 1 species taken at a single Station). 

 Tltamnostylus (contains 1 species taken at a single Station).
