Harris and Crawford : 



is responsible for the south bank of the stream being littered', 

 with angular fragments, which yielded crinoid remains, brachio- 

 pod fragments, polyzoa, and, strange to say, Diplograptus. 



(vii.) Other Localities. 



On the Romsey Road (Sect. 11, Kerrie) the Grits and asso- 

 ciated shales are alone visible. (See Fig. 3.) 



At the head of Evans Creek, Grits outcrop, and have al- 

 ready been mentioned. Their relation to Nemagraptus — Dicello- 

 graptus shales lower down the creek is not clear. If massive; 

 sandstones just upstream from the shales belong to the Grit series 

 the two are in all probability unconformable. 



Other areas of Grit occur near Mount Holden, south and. 

 west of Red Rock, and at The Gap and Mount Tophet. South- 

 west of Mount Tophet we get Diplograptus-Climacograptus 

 shales, but their relation to the Grit is not evident. They may 

 be its associated shales. 



The close relation of the Grits tp the normal Upper Ordovician 

 will be at once seen from the following summary: —

III. Conglomerate Ck. and 

 Bracken Gully - 



Grits apparently bent in syncline overlying 

 Dicranograptus shales. Dip and strike 

 in agreement, and beds apparently con- 

 formable. 



Grits apparently overlying Dicranograptus 

 shales. Faulting. Junction not seen. 



Diplograptus shales in creek, then Grit band 

 and, after a considerable space,. 

 Dicranograptus shales. Relations not 

 shown. 



Grits apparently overlying conformably 

 Diplograptus shales and faulted with 

 them. 



Grits apparently forming syncline, overly- 

 ing Dicranograptus shales. Junction not 

 observed. On west passing to normal 

 Upper Ordovocian without any ob- 

 served unconformity. 



Grits and Diplograptus shales apparently 

 folded together. Some difference in 

 strike.
