Graptolite Beds at Ddi/lesford. 283 



The bifidus-heds at 42 and 43 are east of the fruticosus beds 

 at 41, with some excess of easterly dips intervening. 



In ever}' case, then, where the rehitions of the bifidus and 

 fruticosus beds are observed, the bifidus beds are the newer. 



The field relations of the caduceus beds were not so well 

 observed, but the fdUowiiio^ points seem important: — 



D. caduceus was never conspicuous in the localities in which 

 D. bifidus is abundant, and was never noticed present with T. 

 fruticosus. Easterly dips prevail east of the anticline at 18 to 

 the head of Smith's CYeek. Anticlines and synclines near here 

 have a distinct and consistent southerly pitch. The caduceus 

 localities 44 and 45, and Mr. Baratrwanath's locality lie to the 

 south-east from here. 



No re2>etition of the fruticosus beds occurs between the 

 eastern localities with caduceus, and the furthest east localities 

 with abundant bifidus. 



Xo repetition of the caduceus beds occurs to the far west in 

 any of the localities examined. 



The caduceus beds without typus certainly cannot be placed 

 between the bifidus and fruticosus beds, in both of which typus 

 is abundant, and the field evidence is too complete also to sup- 

 pose they had been overlooked in this po'sition. They must 

 either be below the fruticosus beds or above the bifidus beds. 

 All the field evidence favours the higher position. 



Of the three groups of beds the order then is: — 

 3rd. Beds with abundant D. caduceus, newer than 

 2iid Beds with abundant D. bifidus and with P. typus, 



newer than 

 1st Beds with 7'. fruticosus and P. typus. Oldest here 

 obseiwed. 



This is in agreement with the determinations at Castlemaine 

 already refeiTed to, but I have not here collected in beds which 

 can be decisively referred to that part of the series in which D. 

 caduceus has begun to be common and P. tyjnis has not yet 

 distippeared. On the other hand, there are apparently beds at 

 Daylesford, above the horizon at which T. fruticosus ceases to 

 be common, but older than the beds with abundant D. bifidus. 

 Tliis may be o^nly a local unimportant peculiarity of the bed in 

 which the fossils were collected at locality 22.
