lobsters. Lastly, some of these wyers are knotted, and others of them 
fairly subdivided or branched.”* * * § 
Besides the several species of these animals, which have been 
spoken of in the foregoing pages, some others have also been described, 
which differ sufficiently from these to allow of their being considered 
as different species. 
Mons. Davila has given a plate, representing a dark schist from 
the Duchy of Wirtemberg, on which appears a group of articu- 
lated tentacula, adhering to a calyx-formed basis.-f* This, in Mr. 
Walch’s opinion, is one of the terminations of a pentacrinite, disco- 
vered by Gmelin.J, This, however, does not differ in the least from 
the remains of these animals, which are constantly observed in the 
slabs from Dorsetshire. In the same work a specimen is represented, 
which is a piece of the yellow fissile stone from Pappenheim, bearing 
on its surface the remains of some animal, in many respects analagous 
with the pentacrinites. Ten arms, rather thinly beset with jointed 
tentacula, are discoverable ; but no traces are seen of the trunk of the 
animal, nor do the parts, which are here preserved, bear a resemblance 
to any species of this animal which has been hitherto noticed. This 
specimen belonged to Professor D'Annone.§ A specimen of part of 
a vertebral column, formed of four sides, has been represented, Plate 
XIII. Fig. 59} similar to what has also been remarked by Rosinus. 
Mons. Schultz describes one of these animals as having a quadrangu- 
lar base and eight rays.|| Mons. Guettard also describes one of these 
animals, the pifimary rays of which are four, and dividing repeatedly 
dichotomous, terminate in numerous small branches.^
