Space the Body regularly divides into five Parts fi- 
gured like Leaves to the Edge. Thefe Leaves are 
narrow at the Apex, greatly widen toward theBottom, 
and narrow a little again at theirEnd. Each Divifion or 
Leaf is bounded on each Side by a Row of parade! 
Ridges, which are accompanied alfo on each Side 
of every laid Row, with two other Ranges of Points 
or Knobs ; all which Rows do not meet or clofe 
together at the lower End of the Divifion, but Lave 
a void unwrought Space : A Row of larger irregular 
Knobs runs through the midft of each Leaf. From 
the Divifions between each Leaf runs a rugged knobb’d 
Pillar, which is join’d to the Edge : The other Parts 
between the Leaves and the Edge are Hollows, or 
void Spaces. The Edge or / imbus is of a thick 
cylindric Make, runs quite round the who e Body, 
and only has fome Signs of being disjoined at the 
one Extreme of the Length, or where the Aperture 
was j the Stone anfwering which is here extended a 
little cylindrically outward like an Appendage, and 
was fo formed by the ftony Matter being too much 
in Quantity for the Shell, and fo was protruded 
through the faid Foramen. On the outer Edge of 
the Limbus are fome few irregular ftony Con- 
cretions. The Bafis is flat, and is likewife divided 
into five Parts from the Center, which is one of the 
Foramens ; the other Fcramen (as has been above 
delcribed) being placed at one of the Extremes of 
the Length. This Foramen or Center is about the 
Size of a Shilling. The five Divifions extend to the 
utmoft Edge of the Body, or quite over the Limbtis , 
contrary to the Divifions on the upper Part, which 
extend only to it. Each Divifion is formed by a 
ftony Line edged on each Side with ftony cylindrical
