Genus Cuiaporora, Hall, p. 137.—Ramose or reticulate, ©. Z 
branches cylindrical or slightly compressed, terminations terete ; 
coral composed of a series of tubes or cells radiating equally on 
all sides from the axis, and opening upon the surface in rounded 
or subangular expanded mouths; cells more or less closely ar- 
ranged, but not always contiguous and apparently destitute of 
septa or rays. The cells when filled with calcareous matter fre- 
quently separate in prismatic forms like Favosites, but there is no 
evidence of transverse septa. ‘The cells are not always contigu- 
ous, and there is often a space between the cells which appears 
to be solid in one or more species.—Sp., C. seriata, C. cespitosa, 
C. cervicornis, C. fibrosa, C. multipora, C. macrophora, C. re- 
ticulata. 
Genus Catopora, Hall, p. 144.—Ramose or incrusting with a 
columnar structure; cells tubular with the apertures circular or 
petaloid, not contiguous, and having the intermediate spaces oc- 
tate ; tubular cells rarely septate.—Sp., C. elegantula, C. florida, 
C. laminata, C. aspera, C. nummiformis. The Hetiopora 
crassa of Lonsdale is probably of this genus. 
Genus Tremaropora, Hail, p. 149.—Ramose or incrusting, 
composed of tubular cells more or less closely arranged ; inter- 
mediate spaces solid on the surface, but in the interior transversely 
septate ; cells not septate; apertures oval or circular, often con- 
tiguous, margined by a thin elevated border or calicle, which on 
the lower side is often prominent or labellate. Near Calopora, 
but calicle or elevated rim more conspicuous, and intervals be- 
tween cells solid instead of cellular—Sp., J’. tuberculosa, T. 
coalescens, T'. tubulosa, T'. punctata, T. ostiolata, T. solida, Es. 
triata, T. granulifera, T. aspera, T. spinulosa, T. sparsa. — 
Genus Srriarorora, Hall, p. 156.—Ramose ; corallum solid ; 
stems composed of angular cells; apertures of the cells opening 
upon the surface into expanded angular cup-like depressions ; 10- 
terior of the cell rayed or striated, striae extending beyond the 
aperture of the cell_—Sp., S. flexuosa. ae

fronds, and on all sides of the stems and branches of ramosé _ 
forms; apertures of cells more or less quadrangular, regularly at- — 
in series parallel to the direction of stems, or obliquely 19 
quincunx order. Near Retepora in habit.—Sp., C. aleicornis, 
C. frondosa. 
Genus Ceramorora, Hall, p. 168.—Bryozodid. Incrusting OF 
flattened hemispherical forms; cells arranged in alternating 
ricate series; apertures arching or triangular, with the ape
