Didymograptus bifidus, J. Hall. 



Didymograptus caduceus, Salter. 



Phyllograptus cf. typus, J. Hall. 



Tetragraptus serra, Brong. 



Dichograptus octobrachiatus (juv.), J. Hall. 



Goniograptus crinitus, T. S. Hall. 

 From Basin Creek, south of this last locality, Dr. Hall* has re- 

 corded graptolites belonging to the same zone. 



Middle Castlemaine beds with Phyllograptus and D. caduceus 

 occur along the Upper Pyrete. 



Upper Castlemaine and Darriwil graptolites are found in many 

 parts of the district, west of Glendoon Creek, on the Glendoon 

 Spur, and at the new but now abandoned slate quarry south-west 

 of Slocombe's Corner, but particularly along Goodman's Creek 

 (Upper Castlemaine), in Cockatoo Gully, and between the 

 Bacchus Marsh Road and Woodend. Along Jackson's Creek, 

 above Gisborne, slate bands are common. At localities like the 

 old slate quarry on the creek north-west of Gisborne, a good 

 collection of Upper Castlemaine forms may be obtained, while 

 further down the creek near Ba 69 and Ba 71, and north of 

 Ba 70, Lower Darriwil forms occur, the following being re- 

 corded : —
