met with, and which he had found in Caldey Island, he says, “ At 
originem, si attendamus, non aliud revera est, quam stellffi cujusdam 
fossilis modiolus.”* 
These fossils are found in great numbers in the mountains of 
Switzerland, particularly in those of the Canton of Zurich, and of 
Schalfhausen. The form which they bear certainly approaches very 
nearly to that of a clove. The lower extremity is pierced in its centre, 
with a small opening, which is surrounded by a crenulated surface, 
fitted for articulation with a trochital vertebrae. From this termina- 
tion the body of the fossil gradually enlarges, and is so extended, as 
to terminate in five points, with five intermediate circular margins; 
and to form, in the upper part, a slight concavity, answering to the 
pelvis in the larger encrinites, with a relieved stellated figure in its 
centre. In each of the circular margins are two depressions, in which, 
in all probability, were fixed the first ossiculae of the arms of this ani- 
mal. Viewing this body with a lens of tolerable power, it is seen, 
that a suture passes from each of the five points, just described, 
through the centre of the inferior extremity ; dividing this body into 
five ossiculffi, as we saw was the case with the Ossa Innominata of the 
lily encrinite. That this, agreeable to the opinion of Rosinus, is the 
central part of some species of encrinites, not yet known, is all that 
can at present be asserted of it. With respect to its vertebrse, it is 
observed by Mr. Walch, that one of the barrel-formed trochitae has 
been seen attached to the articular surface of this body. This obser- 
vation encouraged me to offer a conjecture that it may be the pelvis 
belonging to the barrel-formed vertebrae. Fig. 78, last described ; the 
organ of attachment belonging to which, I have ventured to suppose, 
was the body I'epresented Fig. 77- This opinion being correct, the 
appellation of The Clove Encrinite appears to be applicable to 
this species.
