bafes of fix dichotomous teflaceous arms, or branches, 
(perhaps five is the natural number, for one feems 
irregularly placed.) Thefe lower parts, or bafes of 
the branching arms, confifi of three joints each, and 
furround the cup, to which they feem united : each 
of thefe divide into two other jointed branches, that 
are round or convex on their under fide, but fiattifh 
on the upper, with a deep groove running along the 
middle, which is furnifhed with two rows of fuckers, 
as in the fepiaa and afteritE. From the upper edges 
of each alternate joint of thefe branches, arife two 
rows of fmail jointed claws, like fingers ; thefe two 
oppofite rows bend in towards each other : each fmail 
branch, or finger, is about half an inch long, and 
one twentieth of an inch broad j the fize of thefe 
joints diminifh a little, till you come to the laid joint, 
which ends in a point. Each of thefe joints is pointed 
at top, and being concave, embraces the lower con- 
vex part of the next above it ; thefe are likewife fur- 
niihed on their concave fide with two rows of fuckers, 
clafping together j they fecure their prey with thefe 
oppofite claws, or fingers. 
As the finer and more fubdivided branches were 
broken off, when I received this fpecimen, I fhajl, 
in order to give fome idea of them, lay before the 
Society drawings from two curious fofiils, belonging 
to the excellent cabinet of Mr. Francomb. One of 
them (B) fhews all the ramified arms of the head 
dofed up together, and the other (C) plainly fhews 
the fmail internal claws, or fingers, proceeding from 
thefe arms. Thefe were found at Pyrton-paffage in 
Gloucefterfhire, The fofiils themfelves, with that of 
Vol. LII. A a a the
