Middle Utica or Batostoma jamesi Beds. 
No sharp dividing lines can be drawn separating this series 
of beds from either the lower or upper Utica. The thickness 
is about 120 feet. This division has a somewhat less propor- 
tion of limestone than the other divisions of the Utica and is 
much less rich faunally. Exposures are not uncommon, but 
are rarely of a character to yield many fossils; that is, they 
usually show the edges of the outcropping strata, but are 
seldom thrown out and given a chance to weather. From 
the abundance of the bryozoan Batostoma jamesi (Nicholson) 
the beds may be known as the Batostoma jamesi beds. 
In addition to the fossils given in the list of those ranging 
through the Utica, the following occur, most of which are 
restricted to this division:
