it is quite certain that it has no relation to the true Eifel species of Goldfuss, which is common in the 
Devonian limestone of Newtown, Bushel, Torquay, Plymouth, &c. (which see below) which has slender, 
even, dichotomous branches and broad transverse diaphragms, We. 
Position and Locality—Wenlock limestone of Wenlock, Shropshire, and near Aymestry, Herefordshire. 
Explanation of Figures —Plate 1. B. fig. 22. Portion of large group, natural size, from near Aymestry, 
shewing the form of the deep cups lined with strong lamellae, and the latter becoming obscure on the 
thick obtuse margin—Fig. 22 a. Ditto, portion natural size, vertical and horizontal sections, the former 
shewing the very loose vesicular tissue of the central area and wide lining of the walls with nearly solid 
sclerenchyme, the latter shewing the primary radiating lamellze extending to the centre, and the secondary 
ones barely projecting within the wide sclerenchyme lining, through which the lamelle may be obscurely 
discerned. 
Genus. CYSTIPHYLLUM (Lonsd.) 
Gen. Char.—Corallum turbinate, or subcylindrical, outer wall thin, marked with longitudinal lamellar 
strie ; radiating lamelle quite obsolete, or only extending a short way from the walls; horizontal and 
vertical sections shewing a vesicular structure throughout, the obscure rows of cells, curving regularly from 
the walls under the centre, where they are rather larger than at the circumference, where some species 
shew short radiating lamellee. 
The obsolete character of the lamelle, their frequent absence, and never approaching the centre, dis- 
tinguish this genus from Strephodes, and the absence of a prominent boss in the centre of the cup, and 
corresponding upward curvature of the rows of cells in the middle of the vertical section, separates it 
from Clisiophyllum. 
CyYsTIPHYLLUM BREVILAMELLATUM (J/°Coy). Pl. 1. B. fig. 19. 
Ref—Ann, Nat. Hist. 2nd Series, Vol. VI. p. 276. 
Sp. Ch.—Corallum elongate, subeylindrical, preserving for several inches a diameter of little more than 
an inch, slightly tortuous, and with obscure, irregular swellings of intermittent growth; outer wall extremely 
thin, strongly ribbed, with alternately larger and smaller vertical lamellar sulci, about four larger and three 
smaller in the space of three lines, at the diameter of one inch (or eighty-four all round), terminal cup 
with a circular depressed centre, equalling rather less than half the diameter, surrounded by an inclined 
outer area: horizontal section, outer area composed of forty-two radiating lamellz (corresponding to the 
stronger external sulci) extending from the walls about one-fifth of the diameter, connected by close 
numerous transyerse vesicular plates, having at the margin an equal number of extremely short lamellz 
(corresponding with the smaller external ridges), internal area broad, formed of large vesicular plates 
irregularly arranged: vertical section composed of arched irregular vesicular plates, curving gradually from 
the walls under the centre, small and numerous at the sides, considerably larger in the middle. 
It is possible that Mr Lonsdale’s second figure of Cystiphyllum Siluriense, t. 16. bis f. 2, may be a 
young group of this species; as this figure by its narrow form, radiated cups, &c. seems totally distinct 
from his fig. 1, which is the true type of his species, a new specific name would be required for it in 
any case. 
Position and Locality—Wenlock limestone of Wenlock, Shropshire. 
Explanation of Figures.—Plate 1. B. fig. 19. Natural size from Wenlock.—Fig. 19a. Ditto, vertical 
and horizontal sections, the former shewing the loose vesicular tissue in rows, gradually curving downwards, 
the cells being much larger in the middle than at the sides, where they correspond to the small lamel- 
liferous area of the horizontal section.
