One other specimen is quite free from, or destitute of a 
disc—the stolons and fupicle being quite naked. The 
funicle is straight and narrowly cylindrical. forked at each 
extremity, each fork making an angle of 135°—a right 
angle and a half. The fow branches or stolons thus 
produced, give rise to the four zigzag or goniate arms of the 
polypary by a continued process of gemmation and bifur- 
cation at regular intervals. The angles formed by the 
zigzag or goniate stolons become more obtuse as the distal 
extremity of the polypary is reached, where they form 
a nearly right line. 
At each one of the re-entrant angles, there arises one 
simple celluliferous stipe of greater or less length, according 
to the size and age of the polypary, and according to the 
proximity to, or distance from the funicle. These fossili- 
ferous stipes are disposed in alternating manner on each 
side of the arm, and making right angles one set with the 
other. In the specimen under examination, these celluli- 
ferous stipes vary from a little over one inch in length, at 
the distal extremity of the arm, to more than three inches 
near the proximal end of the same. 
The arm itself is a little in excess of two inches in length, 
and all four are sub-equal, disposed regularly and symmetri- 
eally so as to form a large + shaped figure, or cross with 
equal (sub-equal) arms, but bearing celluliferous stipes in 
such a manner that they form two similar series of parallel 
lines occupying two vertically or diagonally opposite areas. 
The angles which these celluliferous stipes make with 
the general direction of the arm is generally 450°, but in’ 
most of the examples the angle diminishes gradually 
towards the distal extremity where they make an angle of 
10° only. The most perfect arm contains twenty-one celluli- 
ferous stipes , tev on one side and eleven on the other side of 
the arm. The arm, diagonally opposite, exhibits nine 
celluliferous stipes on each side: eighteen in all. 
The third arm whose apex is twisted and somewhat 
crushed holds seventeen arms; eight on one side and nine on 
the other. This arm is somewhat shorter than the two 
preceding, whilst these first three are complete.
