Affinities of the Zone D Fauna. — Of this list 28 per cent oc- 

 cur in Zone E, 24 in Bowden, 15 in Bluff 1, 14 in Bluff 3, 10 in 

 H, 8 in F, 7 in I. The reciprocal percentages are : 10 to E, 2 

 to Bluff 1, 1 to F, 1 to Bowden, .8 to H, .7 to Bluff 3, .4 to I. 

 The strong bond is with E. The genus Cerithium is so abundant 

 that we called D the Cerithium zone in the field. Both D and E 

 contain the striking species Costellaria Bicllennewtoni which we 

 found nowhere else. 



Fauna of Zone E. — The following molluscs were collected :
