PLATE XVI. 



FIG. 1. Part of the vertebral column of the pear encrinite of Bradford. 



2. The superior vertebrae, gradually increasing in their diameter. The granulated 



appearance at the inferior part of this specimen proceeds from the attachment 

 of some coralloid body, which has become petrified with the encrinus. 



3. One of the vertebrae, last described, seen detached. 



4. The clavicle, which is seen attached to the other parts, Fig. 6, 7, and 8. a, 



shewn separate. 



5. Part of the vertebral column, which has acquired an additional covering of a pur- 



plish hue. 



6. One the most perfect specimens of this encrinite that I have seen. Here all the 



parts, particularly pointed out, Fig. 8, are again seen in their natural situation, 

 and connected with the first joints of the fingers of the animal. The existence 

 of the first bones of the fingers was ascertained by careful examination, after 

 a farther clearing of the specimen, but not until the account of this specimen, 

 page 211, had passed the press. 



7. In this specimen the vertebrae are seen in connection with the clavicle and 



scapulae. 



8. A specimen * shewing the several parts in connection : 



a, the clavicle. 



b, the scapulae. 



c, the bones of the arms. 



d, the last series of the bones of the arms, the superior surface having two 



concavities for the reception of the bones of the fingers. 



9. Part of a vertebral encrinal column, with digitated processes passing out of each 



vertebra. 



10. Part of a pentacrinal vertebral column, in the superior vertebrae of which are de- 

 pressions for the insertions of the vertebral processes.

* A variety of formation seems to be observable between this specimen and the one, 

 Fig. 7, in the line connecting the clavicle with the superior vertebrae : in the former a body 

 is discoverable bet ween the last vertebrae and each of the inferior convex points of the body, 

 which I have considered as the clavicle. The admission of these bodies as ribs would render 

 the analogy complete: and sufficient reason seems to exist for this admission j since the 

 specimen, Fig. 7, is much more distinct in its markings than is either of the speci- 

 mens, Fig. 6, or Fig. 8, both of which have a hacked surface, from the spathose crystallized 

 substance.
