II. SPECIES. CYATHOCRINITES TUBERCULATUS. 

 TUBERCULATED, CUP-LIKE, LILY-SHAPED ANIMAL. 



Specific Character. 



A'Crinoidal animal, having a column formed of round compressed joints 

 with radiatingly-striated articulating surfaces ; from each of the five scapulae 

 proceeds an arm supporting two hands. Externally tuberculated. 



Locality. 

 Probably at Dudley, in Transition Limestone. 



Description. 



The specimen (fig. 1 .) from which I have derived the specific character, 

 was presented to uiebyT. SMITH, Esq. of Easton Gray, Glocestershire, through 

 the hands of the Rev. R. HALIFAX, of Standish. 



It is very neat and small, indicating, however, that the species might pro- 

 pably increase to a considerable size. There is but little of the column left 

 which adheres to the pelvis. The costa and scapulae have each a double series 

 of tubercles, arising from the contraction of the muscular integument in such a 

 direction as might give motion to the arm, which is formed of two joints, a 

 common and a cuneiform one. From this two hands proceed, in which the 

 number of joints of the first series amount to two, supporting a cuneiform joint 

 which, on one side gives rise to a finger, and on the other, to four or five joints 

 continuing the hand and forming its second series, on whose summit a cunei- 

 form joint adheres and sends off two fingers. 



Externally the arms, hands, and fingers, are ornamented with four or five 

 longitudinal impressions, the result of contraction. 



C. STOKES, Esq. of London, had the kindness to send me a drawing (fig. 2.) 

 of the fingers of an Encrinite, from Dudley, which I apprehend belong to this 

 species, and as it conveys a correct idea of the manner in which the animal 

 contracted them, I have annexed a figure of it.
