of the left hand branch shews a portion of a terminal cup with the broad, smooth diaphragm forming its 
bottom.—Fig. 104. Do. Horizontal section, magnified three diameters, the outer vesicular area forming two 
rows of small connecting plates between the lamellze at their origin. 
Genus, CANINIA. See page 28, 
CANINIA GIGANTEA (Mich.) 
Ref. and Syn.—Michelin, Iconog. p. 81. = Siphonophyllia cylindrica, Se. M°Coy, Carb. Foss. Irel. t. 27. f. 5. 
Sp. Ch.—Corallum simple, nearly cylindrical ; a specimen five inches long, imperfect at each end, two 
inches three lines in diameter at the larger, being one inch ten lines in diameter at the smaller; girt with 
nearly regular obtuse rings of growth about four lines apart; the above greater diameter shews the lamel- 
liferous cylindrical area, one inch six lines in diameter, radiated with about sixty-nine strong, subequal, 
biplated lamellze, with smooth sides, reaching rather more than half way to the centre, where they sink 
to the level of the smooth, nearly regular, horizontal diaphragms, the flattened part of which is about ten 
lines in diameter, surrounded by a margin, abruptly deflected at an obtuse angle to the boundary of the 
inner area; two or three of the lamellz nearly obsolete at the siphonal depression; lamellae connected by 
numerous close, curved, oblique, vesicular plates; outer or perithecal area, surrounding the inner or lamel- 
liferous area, increasing in width by age, formed of nearly uniform strong cellular tissue, composed of very 
numerous curved, oblique, vesicular plates, faintly, or not at all, radiated by delicate costal prolongations 
of the radiating lamellze. 
Position and Locality.— Common in the impure carboniferous limestone of Castle-town Bay, and 
Searlet, Isle of Man. 
CANINIA SUBIBICINA (J/°Coy). (Not figured). 
Ref.—M°Coy, Ann. Nat. Hist. 2nd Series, Vol. VII. 
Sp. Ch.—Corallum much curved, increasing, when young, at the rate of six lines in one inch to a 
diameter of one inch three lines ; after which it remains nearly cylindrical for two or three inches more; 
surface with a thin, nearly smooth, epitheca, marked with obsolete transverse undulations of growth ; when 
the epitheca is removed, the very fine, equal, costal strize are brought into view, five in two lines at a diameter 
of one inch two lines; the outer, small, vesicular area is rather more than a line wide, within which the 
sixty-five thick primary radiating lamellze extend, about four lines towards the centre, leaving the broad, flat, 
smooth, slightly undulated central portion of the diaphragms about six lines in diameter in parts of the cireum- 
ference ; short secondary lamellee appear one between each of the primary ; lateral siphonal depressions strongly 
marked ; vertical section shews the outer vesicular area (at about the above diameter) one and half line 
wide, composed of about four very oblique rows of small rounded cells, extending upwards and outwards, 
from the broad deflected edges of the diaphragms, which latter are thick, tolerably regular, nearly hori- 
zontal in the middle, about three interdiaphragmatal spaces in two lines. 
This species is most nearly like Fischer de Waldheim’s figure of his Turbinolia (Caninia) ibicina, 
from which it differs in the greater number of the lamelle, &c. It differs from the C. gigantea in its smaller 
size, slender form, more regular and smoother surface, much finer cells of the narrow outer area. I suspect 
this may be the coral quoted occasionally by authors from mountain-limestone, under the name of the 
Devonian Cyathophyllum flewuosum, to the figures of which it bears some resemblance in external form, 
but from which it differs in its greater size, coarser lamellar striz, deflected edges to the diaphragms, siphonal 
depression, &e. 
Position and Locality—Not uncommon in the carboniferous limestone of Kendal. 
Genus. CYATHOPSIS (D’Or¢.) 
Ref—Prodrome, p. 105. 
Gen. Char.—Corallum simple, elongate, conic, outer wall thin; radiating lamell strong, reaching the 
walls, but not reaching the centre ; no outer perithecal vesicular area between the ends of the lamellze and the
