Fig. 2, is well calculated to give a satisfactory notion of the form 

 which the arms, fingers, and tentacula assume in a contracted state. 

 In the middle of the lower part of this specimen, three of the sca- 

 pulae and the ramified arms may be seen ; the fingers and tentacula 

 closely filling every intermediate space. 



In the specimen from Charmouth, Plate XVIII* Fig. 1, a very beau- 

 tiful display of the arms, Sec. of this animal is exhibited. In this spe- 

 cimen, neither the arms nor tentacula are more than half extended ; a 

 tolerable notion may, however, be obtained, from this figure, of the ex- 

 tensive power which this animal possessed of collecting its prey, and 

 of directing it to its mouth. 



On viewing the numerous arms with which this astonishing animal 

 is gifted, you will, I trust, readily agree with me in the propriety of 

 distinguishing it as the BRIAR^AN PENTACRINITE. 



The finest specimen of this species which is, I believe, known, 

 is in the possession of Charles James Harford, Esq. of Stapleton, 

 near Bristol, a gentleman well known for the zeal and ability 

 with which he has prosecuted his researches in this Science. This 

 fossil was found in a quarry at Keynsham, on the spot where Mr. 

 Harford's extensive works are carried on. It was discovered eight feet 

 below the surface, and beneath one solid bed of stone, two feet eight 

 inches in thickness. By very great care in its removal, under the di- 

 rections of Mr. Harford, a slab upwards of five feet in length, and 

 four feet in width, entirely made up of the remains of this animal, was 

 taken up, and deposited in that gentleman's valuable collection. Five 

 or six of the vertebral columns of the pentacrinite traverse the length 

 of the slab, the remaining part of the surface containing the detached 

 as well as the connected pieces of the articulated vertebral processes, 

 and of the arms and tentacula of this astonishing animal. 



Having never seen, in any fossil, any body which could be consi- 

 dered as the lower extremity or organ of attachment of this species
