Sp. char. The very full and comprehensive description given 

 by Prof. M'Coy renders it unnecessary to redeseribe this shell. 

 The specimen figured appears to be a somewhat more elongate 

 variety of this species than the generality of specimens met 

 with. It is from the " Encrinite-bed," cement-stone group of 

 the Lower Carboniferous rocks at St. Andrews, cabinet of Dr. 

 Traquair. 



Obs. I wish more particularly to note the extensive range 

 of E. unioniforrnifi^ both geologically and geographically. 

 From the Lower Carboniferous or Calciferous Sandstone beds 

 of Cove Harbour, Cockburnspath, Haddingtonshire, it has 

 been recorded by the late Mr. Salter* ; it occurs here, accom- 

 panied by other marine shells, in an impure limestone above 

 the coal-beds and sandstones of that locality. We next have 

 the present example from the Encrinite-bed at St. Andrews, 

 of the Fifeshire Lower Carboniferous series, not far from the
