Tertiary.'] PALEONTOLOGY OF VICTORIA. [Echinodermata. 



11 In the blocks between c and d are found the largest and most 

 perfect specimens of the Graphularia Robince (McCoy). 



"Perhaps the most interesting bed in the quarry is rf, at the 

 bottom of the marl, and on top of the limestone. There is a 

 deposit there of immensely hard and most irregularly-shaped 

 nodules of limestone. In or about this stratum have been found 

 the Cetotolites Leggei (McCoy), C. Pricei (McCoy), and C. 

 Nelsoni (McCoy) ; the various teeth of the Squalodon Wilkinsoni 

 (McCoy) ; vertebral and flattened bones, small Echinoderms, and 

 the largest of sharks' teeth. 



"Although fossils are to be found in almost any part of the 

 quarry, the four beds which I have described are the places to look 

 in order to see them in profusion."
