G. subsulcatus. Brown, Tr. Man. Geo. Soc. I. p. 214, pi. 7, 
figs. 9, 10. 
Sub-rotund; ambit broad, sub-depressed, with a deep sulcus 
in its centre; constrictions w r ide, nearly equi-distant, rather 
deep, plain, rounded, narrow, below them on the surface smooth, 
and arcuated as they pass over the ambit; surface covered with 
transverse, strong, bifurcate, gently bending striae, which ema¬ 
nate from the umbilicus, where they are strong, the bifurcations 
terminating on the margin of the dorsal sulcus; umbilicus 
rounded, rather wide; aperture semi-lunar and rather small ; 
dorsal lobe short, the whole lateral lobes rounded. Diameter 
five lines, thickness three lines. 
Found in nodules of Limestone Shale, in the neighbourhood 
of Hebden Bridge. Bare.

G. Dorsalis. Brown, Tr. Man. Geo. Soc. I. p. 214, pi. 7, 
figs. 11, 12, 13. 
Discoidal, sub-compressed; ambit somewhat flattened, and 
sub-carinated in the centre ; aperture longer than wide ; whole 
shell covered by numerous, fine, acute, transverse striae, thick 
as they emanate from the umbilicus, and become bifurcate as 
they diverge outwards, and are abruptly arcuated as they pass 
over the side towards the ambit; these are crossed by rather 
wide-set, spiral, and nearly obsolete striae; constrictions irregu¬ 
lar, shallow, and striated, and considerably arcuated, as they 
approach the ambit; septa with two rounded lateral lobes; one 
pointed lateral sinus, and a simple, rounded, central dorsal 
lobe. Diameter seven lines, thickness about one line and a half. 
Found in nodules of Limestone Shale, at High-Green Wood, 
Yale of Todmorden. 
5. Goniatites jugosus. —The Pddged Goniatites, pi. 
XXI.* figs. 14, 15. 
G. jugosus. Brown, Man. Geo. Tr. I. p. 215, pi. 7, f. 14,15. 
Discoidal: with five gradually enlarging volutions, crossed 
by numerous, elevated, sharp, strong, oblique ribs, which ema¬ 
nate from the umbilicus, and become bifurcate, or trifurcate, 
gradually thickening as they approach the ambit, terminating 
in a gentle curve on the margin of the broad, smooth, dorsal 
sulcus with which the slightly-rounded ambit is invested ; the 
sides of the shell rise abruptly, and have a carinated aspect; 
constrictions irregular, shallow, and partaking of the same cur¬ 
vature as the ribs ; aperture compressed and semi-lunar; um¬ 
bilicus very small and shallow; dorsal lobe of the septa narrow, 
truncate, with parallel sides, lateral lobes, and sinuses rounded. 
Diameter three lines, thickness one line and a half. 
This species has somewhat the aspect of G. Gibsoni, but differs 
in the dorsal groove being smooth, and in the form of the septa. 
A rare species, found in the Limestone Shales in the neigh¬ 
bourhood of Hebden Bridge. 
G. Goniatites splendidus. —The Splendid Goniatites, pi. 
XXL* figs. 10, 17, 18. 
G. splendidus. Brown, Mau. Geo. Tr. I. p. 215, pi. 7, figs. 
1G, 17, 18. 
Discoidal, smooth, glossy; inner volutions enveloped in 
the outer one; umbilicus minute; ambit subacute; aperture 
large, wide, oblong-ovate; surface covered with sigmoidal strias; 
septa numerous, the dorsal lobe long and truncate, with the 
sides parallel; dorsal sinuses trifid, with the first lobe very 
long, and rounded; second acute; third short, and obtusely 
angular; lateral sinuses very wide, divided into two parts by a 
very deep acute lobe, the first part bifid, the second rounded. 
Diameter nearly half an inch, thickness a quarter. The young 
form is unknown. 
Found at High-Green Wood, near Hebden Bridge, and is 
in the cabinet of Mr. Gibson. 
7. Goniatites Kenyoni. —Kenyons Goniatites, pi. XXI.* 
20 . 
G. Kenyoni. Brown, Tr. Man. Geo. Soc. I. p. 216, pi. 7, 
figs. 19, 20. 
Somewhat ovate, compressed, smooth, the outer volution 
enveloping the others; ambit rounded, with a thin sharp carina 
along its centre; umbilicus small, shallow; surface covered 
with very minute, spiral striie, which can only be detected by 
the aid of a strong lens ; septa numerous, with rounded lobes 
and sinuses; lateral sinus wide, double; dorsal sinus simple. 
Diameter two lines and a half, thickness a third less. 
This species differs from G. Looneyi in its dorsal sinus being 
simple; and from G. Gilbertsoni in having double lateral 
sinuses, and in the dorsal sinus being simple; and from both 
in being spirally striated. 
Found in the Limestone Shales, near Hebden Bridge. 
8 . Goniatites paradoxicus. —The Paradoxical Goniatites, 
pi. XXL* figs. 21, 22. 
G. Paradoxicus. Brown, Tr. Man. Geo. Soc. I. p. 216, pi. 
7, figs. 21, 22. 
Elliptical, sub-depressed, smooth, shining; aperture sub¬ 
rotund ; umbilicus of moderate size, shallow, the sides gradually 
rising from it; ambit sub-compressed, gently rounded ; surface 
covered with very minute spiral stride; septa with rounded 
lobes and sinuses; the dorsal sinus double, lateral sinus simple. 
Diameter two lines, thickness a line and a half. 
Distinguished from the G. Kenyoni by the form of its septa; 
and from the G. Gilbertsoni in being spirally striated. 
Found in the Shale at the bottom of High-GreenWood, Vale 
of Todmorden.
