do something towards a better understanding of the deposits. 

 That there are different horizons is what we should expect to 

 find, and though lithological and bathymetrical conditions will 

 constantly have to be kept in view as affording some explanation 

 of differences in the faunas of different localities, still to ascribe 

 everything to this and to "colonies," is surely asking more than is 

 likely to l)e granted. An examination of the published lists of 

 fossils from the lower beds of Muddy Creek,* Mornington, 

 Gellibrand, and Camperdown,t Lower Moorabool Valley (Fyans- 

 ford, etc.), J Belmont and Curlewis.i^ Bairnsdale,|| will show that 

 these beds are on much the same horizon, though the exact 

 relationships are not yet definitely fixed. Xo lists have been 

 published for Corio Bay, Altona Bay, Newport, or Mui'ghebolue, 

 but our knowledge of the desposits enables us to refer them to the 

 same series, as the number of fossils at present known to us 

 from these localities is as follows : — 



Corio Bay ... ... 150 species. 



Altona Bay ... ... 70 ,, 



Newport ... ... 115 „ 



Murghebolu*^ ... ... 102 „ 



From Hhelford we have over one hundred and fifty species, 

 gathei-ed by ^lessrs. Donald Clark, Betheras, and Alex. Purnell, 

 which show that this deposit also may be i-eferred to the same 

 group. 



We have shown that the clays at Curlewis^I overlie a polyzoal 

 limestone similar, lithologically, to that of Alaude, and the same 

 is the case at Batesfoi'd.*^ With regard to the latter place, it may 

 be mentioned as a further confirmation of our previous reading 

 of the section, that the work carried on at the " Filter Quarries " 

 has displayed a face showing the liu^estone capped by about ten 

 feet of eocene clay, rich in fossils, together with a thin clay band
