This talilc clearly indicates that the Scleraxonia are essentially Indo-Pacific in distribution, 

 luit live species being found so far north as Japan, four extending south to Australia and one 

 ti> the Tonga Islands. Wrighiella coccinea strays as far from the type locality as the Cape of 

 Good Hope. Fourtcen of the twehty one hitherto described species are found in the Indian 

 Ocean, which seems the centre of distribution lor the group, and not a single species is surely 

 known to occur in the Atlantic < )cean. 



In bathymetric distribution this suborder is mainly from shallow water, thirty six of the 

 thirty nine species in the collection bein^ found at less depths than 100 nieters, and but t< n 

 ies reaching a depth of over 500 meters. It is a remarkable fact that eight of the ten 

 species referred to are also found at depths of less than 100 fathoms. The paucity of forms 

 found between 100 and 500 meters is doubtless mainly accidental, as it is reasonable to suppose 

 that the eight species found at less than ioo meters and over 500 meters really occur at 

 intermediate depths. 



The deepest dredging at which a species of this suborder was secured in 2264 — 1165 

 rs, where Suberia tnacrocalyx was taken. Next to this comes Solenocaulon querciformis 

 from a depth of 828 meters. But the identification of this specimen is somewhat doubtful.
