Affinities. —This species is very close to Smittina marmorea but differs from 
it in the presence of costules and of areolar pores close together (and not scattered 
punctations) and the constant presence of two frontal pores. 
Occurrence. —Miocene (Bowden marl): Bowden, Jamaica (very rare).. 
Geographic distribution. —Mediterranean at Naples; Atlantic at the Azore Isles' 
(80-130 meters). 
Plesiotype. —Cat. No. 68643, U.S.N.M. 
SMITTINA GRANDICELLA, new species. 
Plate 37, figs. 10-12. 
Description. —The.zoarium incrusts shells in one or more layers. The zooecia 
are distinct, separated by a furrow, elongate, elliptical, large; the frontal is convex 
and formed of an olocyst surmounted by a pleurocyst. The apertura is semi¬ 
elliptical; the lyrule is short and wide; the peristome is little salient, hardly indented 
in the proximal portion, and bears three distal spines. 
Measurements. —Apertura 
7m = 0.12-0.13 mm. 
Za = 0.13-0.15 mm. 
Zooecia* 
\Lz — 0.55 mm. 
I lz = 0.32-0.40 mm. 
Affinities. —This species much resembles Smittina trispinosa Johnston, 1838, 
for it often bears a large avicularium on the line of areolar pores; it is distinguished 
from it in its large jooecial dimensions and in the much less regular arrangement of 
the zooecia. The gemmation is identical, but the lines of the nonseptular walls 
are less rigorously rectilinear and often sinuous (fig. 12). The beak of the avicularium 
is round and salient. 
Occurrence. —Pleistocene: Santa Monica (Rustic Canyon), California (rare). 
Cotypes. —Cat. No. 68644, U.S.N.M. 
SMITTINA DISCOIDEA, new species. 
Plate 38, figs. 1-7. 
Description. —The zoarium is unilamellar, discoidal, very large; the lower face 
is concentrically wrinkled and the nonseptular walls are visible in the form of 
radial costules somewhat salient. The zooecia are little distinct, elongate, more 
r or less marginate; the frontal is very little convex and formed of an olocyst sur¬ 
mounted by a detachable pleurocyst with large interareolar costules. The apertura 
is semilunar; the lyrule is short and lamellose; the peristome is not salient, and the 
peristomie is excavated in the thickness of the frontal wall. The ovicell is globular, 
salient, deeply embedded in the distal zooecium; it is surrounded by a little salient 
collar. On the line of the areolar pores there is an enormous triangular avicularium 
with pivot or with condyles of which the beak is acuminate, salient, and pointed 
upward.
