Figure 2. represents a fine specimen in my possession. I have indicated the probable 
form of the fingers by dotted lines, having only seen portions of them, but none that 
could furnish full information of their complete outline. I have indeed seen fingers made 
up by gluing together finger-joints found at various distances from cach other in the 
Bradford clay, and arranged in a decreasing order ; but as in the Crinoidea each finger- 
joint is not distinguished by an essential character as in those of Mammalia, such a 
representation may prove only deceptive.

, exception of the reproduced arm.
