535. 2. CALLOPORA FLORIDA (n. sp.). 
Pl. XL. Fig. 2 a -/. 
Coral explanate or incrusting, scarcely ramose, often fixing itself upon or incrusting other 
corals j cells tubular, opening upon the surface by floriform apertures, the margins of which 
appear as if formed by segments of six or seven smaller curves ; in perfect specimens, each 
angle of the aperture is furnished with an elevated papillose point. Intercellular spaces with 
one or more rows of angular openings upon the surface; vertical section showing the cells 
tubular, with the intermediate spaces septate. 
This species differs from the preceding, both in the form of the apertures of the cells, and 
in its habit of growth : the general aspect of the surface in other respects is not much unlike. 
It rarely grows in extended branching forms, but the branches are flattened or palmate, and 
end in thickened terminations, in which character it differs widely from the preceding species. 
Its more common habit is that of growing upon or enveloping some other coral, and in this 
condition takes on somewhat the form of the body on which it grows, and rarely attains to 
large dimensions. The surface has a coarser aspect than the preceding or following species, and 
there is no difficulty in distinguishing it from those. 
Fig. 2 a. An enveloping mass, consisting of several distinct layers, which, at the commence¬ 
ment of growth, attached itself to a branch of C. elegantula. During a cessation of 
growth in one part, another species of the same genus commenced growth upon 
the surface of this species, which is again partly overgrown by it at a subsequent 
period, and thus we have the three species in one specimen. 
Fig. 2 b. A portion of the surface enlarged, showing the form of the apertures and of the inter¬ 
cellular spaces. 
Fig. 2 c. A portion of a more perfect specimen, showing the elevated points at the angles of the 
cells. 
Fig. 2 d. A section enlarged, showing the tubular structure, its connexion with C. elegantula, and 
the surface of C. aspera in its connexion with the other two. 
Fig. 2 e. A fragment giving some appearance of branching in a palmate form. 
Fig. 2 /. A section showing the septate character of the intercellular spaces. 
Position and locality. In the decomposing calcareous shale at Lockport. 
536. 3. CALLOPORA LAMINATA ( n . sp.). 
Pl. XL. Fig. 3 a - e. 
Coral massive, irregular in form, composed of thin* solid concentric lamina; penetrated by 
minute tubular cells, which open upon the surface by floriform mouths; spaces between the 
tubes appparently solid, equal to or greater than their diameter ; lower surface covered by a 
concentrically striated membranous expansion.
