XIL The Digitated Encrinite. 
Although the great difference observable between the specimens, 
represented Plate XVI. Fig. 9 and Fig. l6, is sufficient to 
warrant the supposition that there must be two distinct species 
possessing these digitated processes, I have not ventured to 
assume this as a fact ; choosing rather to wait for the discovery 
of specimens which may prove more illustrative of this particular 
circumstance. 
XIII. The Oval Encrinite. Both this fossil and the foregoing are 
described in Letter XXII. 
XIV. The Briarjean Pentacrinite, of Dorsetshire and Somer-
