4 Darriwill series. The fauna of this series is said to differ from the 

 Castleraaine one by the almost entire absence of Didymograptus 

 caduceus and the appearance of Lasiograptus and Glossograptus ; 

 Trigonograptus and several species of Didymograptus and Climaco- 

 graptus occur, while Tetragraptus serra and Loganograptus still 

 persist. 



A comparison of these fossil lists with those from New York and Can- 

 ada leaves no doubt that the general sequence of the American and the 

 Victorian graptolites is the same, but as Mr Hall states " experience has 

 shown that it is unsafe to push the analogy too far and that'the only safe 

 method is that of detailed stratigraphic work." It is added by the same 

 author : " Thus we find forms here associated which elsewhere are separated 

 by intervening zones; and on the other hand, forms elsewhere associated 

 may be here separated." In this connection it is now extremely interesting
