It is at once apparent from this Table that by far the largest 

 number of species (64 in all) have been obtained from Torres Straits ; 

 that is, no doubt, partly due to the large number of dredgings taken 

 and the number of minor localities investigated here. The Eenieridse 

 are the only family of Silicea or Ceratosa which are not strongly 

 represented. The forms most abundant here a.T:e lotrochota purpurea, 



t It is uncertain to which variety the locality given by Hackel refers.
