ICven if not the Juan r'ernandez Hepatics are almost entirely Antarctic as 

 Hkr/jx; thinks, the Antarcto-tcrtiary element is proportionally larger than in any 

 other grouj), and it is not imj)ossible that genera like Megaceros or Harpalejeunea, 

 the island species of wiiich were referred to the neotropical element, are Antarctic, 

 and that this is true also of JUizzaiiia, represented in I and II, but on the other 

 hand we must admit that pantropical genera like Riccardia, Anthoceros, Mega- 

 ceros, Hazzaiiia, Lepidozia, Radula, Madotheca, FruUania etc, may have extended 

 far south during a warmer period and given rise to important groups all around 

 the circumpolar belt, and that we have to show that such disjunct southern groups
