8p. char. The very full and comprehensive description given 

 by Prof. M'Coy renders it unnecessary to redescribe 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. unioniformisj 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
