PEAR ENCRINITE OF BRADFORD. 



653 



siderable numbers in the oolite near Bradford in Wiltshire, 

 under the interesting circumstances already mentioned 

 (p. 505). 



The receptacle of this En- 

 erinite is very smooth, and 

 crossed transversely by fine 

 lines where the plates of which 

 it is composed unite. The 

 stem is short, smooth, and 

 strong; the arms are simple, 

 and bear considerable resem- 

 blance to those of the Marsu- 

 pite. In this drawing (Lign. 

 IAS, Jig. 1), reduced from Mr. 

 Miller's beautiful work on the 

 Crinoidea, a group of these 

 animals is represented as if 

 alive in the water. A few 

 perfect specimens have been 

 obtained ; but the body is usu- 

 ally found deprived of the 

 arms, and broken off at the top 

 of the column (Jig. 2): the 

 vertical polished section (Jig. 

 3), shows the form and ar- 

 rangement of the plates com- 

 posing the receptacle. 



A small species of this 

 genus is found in the white 

 chalk, t
