Cancellaria scalatella n. sp.Pl. II, f. 4.* 
Turreted, umbilicate, spirallj' striate by numerous close 
spiral threads, more elevated on the stout rounded longitu- 
dinal variciform ridges of which there are 6 or 7 on a 
whorl. Suture very deeply sunk. Whorls about 7, slightly 
rounded, angulate and crowned above by the ridges. 
Aperture almost triangular, rounded above, angular and 
formed into an obsolete canal anteriorly. Outer lip sharp, 
grooved within. Inner lip continuous, thin, sharp, 
slightly reflected and bearing two folds. Base angulate, 
perforated b}^ a small round umbilicus. 
Related to C. varicosa Brocchi (Miocene, Piedmont); 
but smaller and of somewhat stouter figure. The spiral 
striae are coarser, and the peristome is finel}^ grooved 
instead of being coarsely dentate only. In C. varicosa 
the spiral striae are cro.ssed by very fine longitudinal ones, 
which do not exist in C. scalatella. The most striking 
difference however is that the whorls are rounder and the 
suture much more deeply sunk in C. scalatella, whilst the 
longitudinal ridges project upon the angle of the whorls so 
as to give a coronate appearance. 
The three Cancellariae hitherto described from the Ja- 
maican miocene are all akin to European fossils of the 
same date ; but two of them belong to the type of the re- 
cent C. reticulata. The present is of more decidedly mio- 
cene aspect than either of the three previousl}^ described. 
Ovulum inimunituvi n. sp. PI. I, f.7 f 
Fusiform-elongate, pointed at both extremities. Outer 
lip thickened, extending in a nearly regular slight curv'e 
from the posterior to the anterior canal ; slightly dilated 
anteriorly. Inner lip with two strong folds at the ante- 
rior end. Aperture as long as the shell ; narrow poster-
