Affinities of the Zo7ie A Fauna. — Of this list 62 per cent oc- 

 cur in Bluff 1, 58 in Zone B, 41 in Bowden, 29 in Bluff 3, 12 in 

 H, 12 in I. The reciprocal percentages are 19 to Zone B, 14 to 

 Bluff 1, to Bluff 3, 1 to Bowden, .7 to Zone G, .5 to Zone I, .4 

 to Zone H. It should be noted also that the few species A has 

 in common with H and I, are those with considerable vertical 

 range. 



Flora of Zone B. — The top of Zone B contains wood and 

 leaves of the Myrtle, Laurel and Mimosa families. Professor E. 

 W. Berry was so kind as to identify them generically for me but 

 their state of preservation was not good enough for determining 

 the species. The genera represented are Eugenia, Nectranolra 

 and Inga. The various woods Dr. Berry remarks are almost 

 surely new species. The range of the genera is such that no 

 special stratigraphic meaning is implied by their presence. 



Fauna of Zone B.— The following molluscs were found :
