This is the fauna referred to by Vaughan at page 16 of his "Belgian 

 paper "^ as agreeing closely with the Petit Granit of the Ecaussines area. 

 It is therefore of C, age. 



The dip is slight, and a considerable area of each bed is exposed. The 

 surface of many of the lower layers is covered with large colonies of Syringo- 

 pora, weathered out in dome-shaped masses, very much as they must have 

 appeared on the ancient sea-bottom. In very many cases the clumps can be 

 seen to be attached to enormous valves of Conocardmm fusi/orme, McCoy (as 

 noted on the Survey Map). Shells may be found covered with the Aulopora- 

 like bases of colonies. 



The following points are noteworthy : — 



Chonetes is entirely absent. 



Caninia cylindrica is small and poorly developed, but appears to be at the 

 Mut. Z or Mut. -y stage. 



Schelwienella crenistria has not the Mut. C type of ribbing. 



' Poorly preserved. Convex brachial valve. Strong growth halts. Alternation of 

 ribbing rarely marked. Cardinal angles not seen.
