To the distribution of the family thus shown, must be added from other sources the 

 Indian Ocean, the Mediterranean, the Caribbean Sea, and New Zealand. The range 

 may therefore be considered to encircle the globe from east to west, but, so far as at 

 [resent known, not to extend into the colder waters either north or south.
