Mr. Guettard, that able and curious naturalid, has 
given, in the Memoirs of the Academy of Sciences 
at Paris, publifhed in 1761, for the year 1755, a 
mod: minute defcription and difledtion of an animal 
of this kind, from the curious cabinet of Madam 
Bois Jourdain of Paris; it was fent from Martinico 
by the name of palma marina ; the head of it, being 
more perfedt than ours, has fome refemblance to the 
branches of a palm tree. 
However, as there is fome little difference in the 
figure of both thefe animals, and as I, about a year 
ago, had the honour of exhibiting to the Royal So- 
ciety a curious drawing of it, which Dr. Gartner, 
of Stutgart in Wurtenburg, F. R. S. drew for me, 
I lhall give the defcription that occurred to me, upon 
the bed examination I could take of it, without dif- 
fering, or breaking the fpecimen. 
As it comes neared to the foffils called encrini, or 
lilii lapidei, I diall dill keep that name, and call it 
Encrinus, Capite dellato ramofo-dichotomo, 
Stipite pentagono equifetiformi. 
The dem and head of this animal, in its prefent 
date, meafures about fourteen inches. The dem is 
about thirteen inches in height, and about the third 
of an inch in diameter, ledening a little towards tne 
top : it is formed of pentagonous joints, or vertebrae, 
placed regularly over one another, which are of a 
tedaceous fubdance, and united by very thin carti- 
lages ; as appears, by examining minutely the bafe of 
the lowed vertebra, where it is fadencd to the darry 
indentures of the joint : this makes the vertebrae ca-
