The Fosstz Remains of this species occur in the lyas near Bristol, at 
Keynsham, Hengrove, &c. 
Description. 
Through the favour of Wm. Crayrietp, Esq. I have been enabled to ex- 
amine the fine specimen once in the possession of the late James (not JoHNn as 
stated erroneously page 11.) Tosin, Esq. In the drawing it up from the bot- 
tom of the sea near the Island of Nevis, in the West Indies, the animal has 
clearly been broken off, leaving its posterior portion behind ; thus we have lost 
the chance of ascertaining the fact, whether it adhered by a fixed base or hada 
locomotive power. The same accident has befallen the other recent individuals 
that have been mentioned when speaking of the locality of this species. How- 
ever, judging from its analogy to the encrinus moniliformis, from its long 
column, numerous auxiliary side arms, and the associated manner in which 
groups of the following species are sometimes found preserved on the surface of 
a single slab, with the columns all tending towards the same point, as if issuing 
from a common base, I conceive that this species also adhered by a base to exe 
traneous matter. This idea gains some further ground, from all the recent 
specimens hitherto found having broken abruptly off in the endeavour to re- 
move them, as not being able to free themselves from the points of adhesion, 
which certainly would have been the case, had the animal possessed a loco- 
motive power. This inference acquires additional confirmation from the ob- 
servations made by the late J. Tozin, Esq. on another specimen, viz.—‘ Some 
“ years ago I was in possession of a larger pentacrinite, which was brought to 
«me so fresh out of the sea that at the bottom (where it plainly appeared to 
«« have been broken off from the rock to which it was fixed) the blood* was 
“ actually oozing from the vertebrae. This specimen I endeavoured to pre- 
“ serve, but it was totally destroyed by the ants, who eat every cartilage, so that 
“it fell to pieces.” 
I cannot admit the assertion of Watcu, that the pentacrinite is an animal 
crawling along the bottom of the sea; but conceive it to have generally stood 
more or less erect in its watery element, yielding to the fury of the storm by 
bending down, and adhering for additional security with its side arms to ex- 
traneous matter, or closing them to the column, and thus offering the least sur- 
face possible to the element. The latter is the most probable idea, since I have
