and a Briarean Pentacrinus .

&INCE my last communication, a singular variety of Pentacrinus 
having been discovered near Lyme, of which I had the good for- 
tune to procure a specimen, it is with pleasure I transmit drawings 
to the Society taken from my own specimen, as well as from some 
fine ones belonging to Mr. De la Beche. 
Fig. I, Plate 22, shews the branching arms, which have consider- 
able resemblance to the species found most commonly at the same 
place, and called by Mr. Parkinson, the Briarean. It differs from it 
however in being thicker in proportion throughout. 
Fig. 2 is the part from whence the arms spring, and the two out 
of the five processes to which they were attached, which are visible, 
are remarkably well preserved. This lies on the under side of the 
lower part of the stone, figured No. 1, and is in all probability the 
identical summit of the column to which the arms of that figure 
were attached. The stem or vertrebal column is peculiar, from being 
in its lower part so nearly circular, that at first it passed for an 
encrinus, (see fig. 1 & 3, Plate 22) but towards the head it ex- 
hibits, as one of the drawings will shew, a decided pentagonal form,
