174 Mr. H. Seeley on new and little-known Fossils 
The column, which is about half the diameter of the calyx, 
slightly enlarges for four or more times the length of the cup, 
and, then contracting a little, terminates in a hollow cone. There 
is also one reinarkable specimen, unfortunately imperfect, which 
appears to show a branching division in the column. 
The dase varies; but in all specimens it expands near the bot- 
tom as it descends, either conically or into a thin plate like the 
base of a Gorgonia. The upper columnar end, at a variable length, 
seems to terminate in a conical cavity like that of the headpiece, 
with which the cylindrical stem corresponds in diameter. In 
this cavity I notice a circlet of twenty-five granules. The ordi- 
nary plates of the column are twice as wide as high, but near 
the articular end get deeper. There is nothing to indicate how 
the two parts were connected, or how the dichotomous part of the 
column came on. 
On the whole it seems most nearly related to Millericrinus. 
The species may be marked Torynocrinus canon. It is the 
Koninckocrinus Agassizi, mihi, of my list in the ‘Annals’ for 
Oct. 1864. 
Another species from Hunstanton, which is doubtfully placed 
in the same genus, should be named ?Zorynocrinus variolarius. 
It is the Apiocrinus of authors, the Bourguetocrinus ellipticus 
(Mill.) of Mr. Rose [Ann. Phil. 1836], Bourguetocrinus rugosus 
(D’Orb.) of Mr. Wiltshire [Geologist, 1859], and the K. rugosus 
of my list [Ann. Nat. Hist. 1864]. 
Of this 1 only know the base and parts of the column. The 
base is an expanded plate contracting conically to the size of 
the thick cylindrical cheese-like pieces forming the column. 
These vary in thickness, but are rarely more than half as high 
as wide. The articular surfaces are ornamented with concentric 
rows of pustules, generally very close together; the outer sur- 
face is smooth. 
Ammonites ochetonotus (Seeley). 
A compressed shell with subparallel sides, a back widely chan- 
nelled, and moderate umbilicus. It is often a foot in diameter. 
The umbilicus is as high as the mouth is wide, moderately deep, 
varying with the variety, flat at the periphery and oblique, 
making an obtuse angle with the side. It commonly shows at its 
outer limit a few large tubercles, in which in the young state the 
close, rounded, flexuous ribs which then ornamented it were 
knotted. 
The ratio in which the height of the side increases, taken at 
each half whorl, is 15: 2:8; and the whorls are coiled nearly 
parallel to the back. In large specimens the sides are smooth, 
gently inflated, shghtly converging, and round rapidly on nearing 
the back.
