copies, Plate I. Fig. 19 and 20, were made, having been originally in 
Mr. Strange’s museum, was most probably obtained, with the former, 
from Verona. 
Plate I. Fig. 20, exhibits the interior part of the fossil. The radii 
are connected at their sides by a substance, which, in the recent 
animal, was doubtlessly membranaceous. The mouth is surrounded 
by five sub-cordiform substances, disposed between the central ter- 
minations of the radii. 
Plate I. Fig. 19, represents the superior surface, which appears to 
have been smooth. The radii, however, are here unexpectedly sul- 
cated ; a circumstance which, however, may have proceeded from the 
contraction of the membrane over them, in its dried state. 
In its general appearance, this stellite resembles the Stella cartila- 
ginea of Aldrovandus ; or Stella membranacea, as Linck would rather 
call it. But its great degree of comparative thickness, and a curi- 
ously-figured process on its sides, mark an essential difference 
between the two, besides that of their size. 
You have perceived, by the preceding account, that the fossil 
remains of these animals are rare. But you will also discover, that 
as far as my reading and observations extend, that the difference 
between the fossil remains and the recent animals does not appear to 
be so great as was observable, whilst examining the fossil animal 
remains noticed in the former volume.
