404 Mr. Giveon Manteur’s Description 
The preceding remarks demonstrate that much analogy exists 
between the Alcyonium Chonoides and the “ funnel-formed fossils” 
described by Mons. Guettard and Mr. Parkinson. Figure 5, 
Tab. xi. of the second volume of Organic Remains, approaches 
very nearly to this species. At page 127 it is mentioned as “ be- 
ing of a funnel-shape, and formed of innumerable tubuli extend- 
ing horizentally from the inner to the outer surface; their bases 
being on the outer, and their other the open terminations, being 
on the inner surface." "The characters of the specimen noticed 
p. 125 of the same volume accord very much with those of our 
fossil. “ It was originally of a funnel-form, but has the appear- 
ance of having suffered compression, the sides of the cone being 
brought nearly within half an inch of each other. The texture of 
the external surface appears to have been very close, and without 
any openings, except the very minute foramina resulting from a 
spongeous texture. The internal surface differs much from the 
external, being so remarkably smooth and regular as to have the 
appearance of the pile of velvet. On being viewed with a lens, 
it is seen that the villous appearance is produced by the infinite 
number of minute openings, arranged as close by each other as 
possible over the whole surface.”—The fossil represented in the 
frontispiece of the same book bears a striking resemblance to 
the Alcyonium Chonoides. It is, however, impossible to decide as 
to the identity of these fossils, without an actual inspection of the 
different specimens. 
The annexed sketches, it is hoped, will satisfactorily prove, that 
nothing has been advanced respecting the structure and physiology 
of the Alcyonium Chonoides whieh is not fully authorized by its fossil 
remains. ‘The substance of the reliquize is generally either calca- 
reous or siliceous ; sometimes it consists of an intermixture of both. 
The specimens are from Bridgewick chalk-pit, near Lewes.
