Zoopuyta. | UPPER PALAZOZOIC RADIATA. 93 
The tubes being rarely in contact, and often cylindrical and flexuous, distinguish this species from its 
congeners. The transverse diaphragms, and absence of radiating lamellie, will serve to separate prismatic 
portions from the other basaltiform corals found with it. 
Position and Locality —Not uncommon in the carboniferous limestone of Derbyshire. 
Explanation of Figures—P1. 3. C. fig. 11. Portions of large mass, natural size, shewing the loose mode of 
growth, and the variation of the columns from round and nearly smooth, to prismatic and longitudinally sul- 
cated ; the tops, by rough fracture, exhibiting the transverse undulated diaphragms with their crenulated edges.

Sp. Ch.—Elongate conic, very gradually tapering (generally about five inches long, with a diameter 
of about one and half inch at the termination) ; terminal cell oblique, oval, the short axis about one-fifth less 
than the long; surface regularly girt at about every quarter of an inch with slightly oblique, strong, cup-shaped 
rims of growth, concave above, and produced by the successive growths from the centre leaving the prominent 
edges of the previous cells; weathered surface finely striated by the edges of the vertical lamelle, of which 
there are about twelve in a quarter of an inch; the horizontal oval section shews the centre to be eccentric, close 
to one of the broad sides, and formed by the slight twisting or complication of the radiating lamellz about an 
imaginary axis ; radiating lamellee very thin, of equal thickness, from one hundred to a hundred and thirty at 
the margin, some stopping and some uniting as they approach the centre, in parcels; all the lamellze connected 
throughout at regular intervals by minute transverse vesicular plates; internal structure exposed by hori- 
zontal and vertical sections uniformly and minutely cellular. 
The great number and closeness of the lamellze distinguish this species from those published forms allied 
to it. 
Position and Locality —Rare in the lower carboniferous Jimestone of Arnside, Kendal (and Lisardrea, 
Boyle, co, Roscommon, Ireland). 
Explanation of Figures—PI. 3. C. fig. 3. Natural size, from Arnside (the top has been ground more 
nearly at right angles to the axis than the true opening of the cup, which latter is indicated by the direction of 
the rings of growth).—Fig. 3a. Do. Horizontal section magnified one-third linear.

Sp. Ch.—Very elongate conic, nearly cylindrical, with a diameter of one and a quarter inch for the 
greater part of its length; strongly and regularly striated externally (about five strie in one fourth of an 
inch) ; external strize corresponding in number to the radiating lamelle; in the transverse rough section the 
central area is rather more than one-third the whole diameter, composed of the edges of confusedly blended 
vesicular plates, crossed by a few faint extensions of the radiating lamellee, and divided into two symmetrical 
portions by a strong median fissure; the space between this inner area and the outer wall is narrow and 
regularly radiated with about fifty-eight equal, thin, rather distant lamellze, connected by numerous delicate, 
transyerse vesicular plates; between each pair at the circumference, a shorter radiating lamella occurs, 
which only reaches half way to the axis, and where they occur, the connecting vesicular plates are smaller 
and more numerous than from thence to the axis, the intermediate open cellular space less than the outer 
one in width ; vertical section indistinctly tri-areal; outer area defined, about one-sixth of the width on each
