the same letters as in Plate XVII. Fig. 15. The specimen, Plate XVIII. 
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, &c. of this animal is exhibited. In this 
specimen, neither the arms nor tentacula are more than half extended ; 
a tolerable notion may, however, be obtained, from this figure, of the 
extensive 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 ot 
distinguishing it as the BuiAiiiBAisr 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 earned 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 directions 
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-
