bit or general appearance from the reft of their con¬ 
geners. Of thefe anomalous Pennatulae the fpecies 
here figured is one of the moft remarkable. It 
confifts of a lengthened cylindrical body, fomewhat 
thicker on the upper part than the lower, of a gra¬ 
nulated appearance, and thickly covered with val¬ 
vular tubercles, thro’ the orifices of which are pro¬ 
truded at pleafure the polype-like tentacula of the 
animal. The colour of this curious fpecies is com¬ 
monly a pale pink, and fometimes a bright purple, 
or crimfon. It is of a foft fubftance, but is fur- 
nifhed with an internal bone, and is fiightly hol¬ 
lowed or channelled on one fide. It is found in the 
Mediterranean fea.
