PLATE' 



Genus. Apiocrinites to face page 17. 



I. Apiocrinites rotundas, p. 19. 



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 each 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. 



II. Apiocrinites rottindus, p. 21. 



III. Apiocrinites rotundus, p. 25. 



IV. Apiocrinites rotundus, p* 26. 



Fig. 14. 20. and 21. arc magnified representations. 



V. Apiocrinites rotundus, p. 27. 



VI. Apiocrinites rotundus, p. 28. 



VII. Apiocrinites rotundus, p. 32. 



Fig. 13. shows the supposed aperture of the ovaries in a specimen drawn on an 

 extended line. 



Apiocrinites eliipticus, p. 34. 



I. Encrinites moniliformis, p. 39. 



Smaller than natural. 



II. Encrinites moniliformis, p. 40. 



Larger than natural. 



III. Encrinites moniliformis, p. 41. 



Genus. Pentacrinites vel Peutacrinus, p. 45. 

 I. Pentacrinus Caput Medusae, p. 48. 



Represents the upper part of Mr. TOBIN'S specimen rather larger than natural size, 

 with its fingers and arms affixed. In the specimen these are broken off with the 

 exception of the reproduced arm.
