F2d Second crinoidal bed. This is 

 D2d 



The following" fossils were found : 



lithologically similar to 

 I foot 



2 Stromatopora coiicentrica? Gold- 

 fuss r 



6 Favosites helderbergiae Hall C 



7 F. sphaericus? Hall 



F2e Iron stain. Though other iron stain lines are noticeable at 

 intervals, one can not mistake this one as it is the most continuous 

 and most pronounced. 



With the exception of W h i t f i e 1 d e 1 1 a ? n u c 1 e o 1 a t a , 

 brachiopods seem to be entirely wanting in the Favosites bed, but 

 immediately above they are very abundant. This is the more notice-

able since the lower part of F3 and the upper part of F2d have the 

 same lithic characters and often weather as a single bed. 



F3 An alternation of coarsely and finely crystalline limestone.

The following is a list of the fossils found here :

This bed is subdivided as follows: 



F3a A coarsely grained limestone mostly composed of crinoid 

 joints, which seems to be a modified continuation of F2d. A few 

 brachiopods were noticed 1-3 inches 



F3b This is of the same lithic character as F4 and doubtless rep- 

 resents the beginning of the latter bed, but the conditions changing 

 brought the typical F3 sediment in again, for at the northern end 

 of the quarry, F4 rests on F3a but as we follow F4 southward, we 

 find it penetrated by a more coarsely grained layer which at the 

 southern end of the quarry attains a thickness of 3 inches. This is 

 represented in the preceding figure [fig-6] 1-3 inches
