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

 Castlemaine 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 w^ork." 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
