culiim. On the other hand, it is quite frequent to find on the same
zoarium some zocecia deprived of spiramen, and which nevertheless
are still living and contain a polypide.
Genus GALEOPSIS Jullien, 1903.

The spiramen is very large and salient. The apertnra has two
cardelles. The frontal is a tremocyst or an olocyst.
Genotype.—Galeopsis rahkhis Jnllien, 1903.
Range.—Maestrichtian-Recent.
Several new species of this well-marked genus are known in the
American Early Eocene.
SCHIZAROPSIS, new genus.
{Schisos, slit; opsis, appearance.)
The apertura bears a straight proximal border notched by" a small
rectilinear rimule. The frontal is garnished laterally with areolae;
it is formed of a very finely granulated pleurocyst placed on a thick
olocyst. The spiramen is almost as large as the peristomice.
Genotype.—Schizaropsis conveica., new^ species. Jacksonian.
SCHIZAROPSIS CONVEXA, new species.

Description.—The zoarium incrusts oysters ;
the zooecia are grouped
in linear longitudinal lines. The zocecia are distinct, a little elon-
gated, elliptical, or rectangular; the frontal is very convex, smooth,
or very finely granular, bordered laterally with six large widely
spaced areolae. The apertura is formed of a semilunar anter and of
a straight proximal border notched by a small rectilinear rimule.
The spiramen is elliptical, transverse, placed on the exterior peris-
tomie, almost as wide as the peristomice. The ovicell is globular,
salient, smooth ; it is hyperstomial and opens by a very large orifice
above the apertura and opposite the spiramen. Two small triangular
avicularia are placed symmetrically on each side of the apertura.
