Gen. Char.—Elongate conic, simple ; an outer variable area of loose vesicular structure ; an inner area of 
broad transverse diaphragms, supporting at their circumference a series of short vertical radiating lamellze which 
do not reach the centre, one or two are deficient at one point of the circumference, and there the transverse 
diaphragms are each prolonged downwards into a sort of siphon; edges of the diaphragms at the circum- 
ference bent downwards, forming a narrow intermediate area. 
I suspect all the simple Cyathophyllw may belong to this genus. In some species the outer vesicular 
area is only added when near its adult diameter, and in all increases proportionately with age. The inner 
edges of the lamell often exhibit the tubular papilla, supposed by Mr Lonsdale to characterise his genus 
Tryplasma.

Sp. Ch —Young corallum very widely conic, attaining the adult diameter of three inches at a height 
of about two inches, after which it remains cylindrical for a height of several inches, marked with irregular 
concentric obtuse undulations and small fimbriated edges of growth; in the young the radiating lamellee 
are alternately longer and shorter, but before reaching the adult diameter they are all thin and nearly 
equal, four or fiye’in a space of three lines at a diameter of two inches nine lines (or a hundred and ten 
to a hundred and sixteen all round) connected by numerous transverse curved vesicular plates ; inner area 
formed of broad horizontal simple diaphragms, which at a diameter of an inch, extend almost across the 
corallum to the exclusion of the outer vesicular and radiated layer, at a diameter of two and half to three 
inches, they maintain a diameter of about an inch, the outer lamellated and vesicular zone having pro- 
portionately increased ; each of the diaphragms is strongly bent downwards at one point of the circumference 
forming a distinct siphon; outer wall extremely thin, forming a few root-like tubercles on the conical 
young ; terminal cup with a depressed flattened centre, and very convex outer area. 
Position and Locality—In the Wenlock limestone of Wenlock, Shropshire. 
Explanation of Figures—P1. 1. C. fig. 12. Part of old terminal cup, natural size, from near Wenlock, 
shewing a portion of the very thin epitheca on one side ——Fig. 13. Do. Natural size, shewing the form of the 
young cup, with one of the diaphragms exposed at base, with the deep siphonal inflection, and a few radiciform 
tubercles from the surface.

Sp. Ch.—Corallum simple, conic, slightly curved, averaging three and half inches long, and varying at that 
length from one inch ten lines, to two inches three lines in width at large end; adult cup deep with highly 
inclined walls, sulcated by the radiating lamellze, which are about ninety-six, alternately longer and shorter, 
nearly equal at the edges, and a broad flat, circular, smooth diaphragm forming the bottom ; vertical section, 
inner area about one-third of the diameter at top, of nearly equal width from base to top, composed of 
very close, irregular transverse diaphragms, about nine in three lines throughout, bending down at one 
point of the circumference to form a thick siphonal inflection; outer area of large curved vesicular plates, 
forming very highly inclined rows of elongate cells, averaging one-third the diameter on each side in adults, 
but gradually narrowing towards the apex, where it almost disappears; outer surface with a very thin outer 
wall, longitudinally marked by equal lamellar sulci, five or six in three lines at the large end; irregularly 
wrinkled concentrically and with occasional irregular papillate protuberances towards the smaller end. 
Although agreeing with M. d@Orbigny, that this is not the Devonian Cyathophyllum turbinatum of
