(Janjukian) beds. This is especially seen in such species as 

 Amphistegina lessonii and Pentellina angularis, which are 

 present in considerable numbers both in the Muddy Creek and 

 Lilydale material, as well as by Polystomella verriculata, in 

 lesser numbers, none of which species has been recorded from 

 the beds in the Adelaide district. Muddy Creek lies on the 

 eastern side of the Murray Basin and Lilydale is situated 

 almost on its extreme western limits, yet this agreement in the 

 foraminiferal fauna of the two localities may indicate a strati- 

 graphical co-ordination and similar geological horizon for 

 the respective beds. 



The height of the Lilydale bores above sea-level has not 

 been accurately determined, but Yunta, the nearest railway 

 station, at a distance of forty-two miles, is 992 feet above the 

 sea. Lilydale is probably a little lower than that.
