ROTALIIDAE—-ANOMALINA; PULVINULINA. 51 
This is a rare species in the collection. It is perhaps closer to 
the figure given by d’Orbigny in the Cuban monograph as Rotalina 
cultrata than the broader form of the species so abundant in 
globigerina-ooze. 
Pulvinulina incerata, new species. 
(Plate 9, Figures 1 to 3.) 
Test unequally biconvex, dorsal side somewhat more convex than the 
ventral, periphery subacute; chambers numerous, 7 or 8 in the last-formed 
coil; sutures oblique, rather indistinct and very slightly, if at all, depressed 
on the dorsal side, nearly radiate and somewhat depressed on the ventral 
side; wall fairly thick, finely punctate, otherwise smooth, ventrally somewhat 
umbilicate, the apertural face of the last-formed chamber obliquely angled; 
aperture elongate, at the base of the last-formed chamber; color white. 
Diameter up to 1 mm. 
At the single deep-water station outside the reef this species was 
fairly common, but elsewhere only a few specimens occur. It is 
rather closely related to certain of the species found fossil in the 
Tertiary of the Coastal Plain region.

Test almost equally biconvex; peripheral margin acute, slightly lobulated, 
carinate; chambers 7 or 8 in the last-formed whorl; sutures somewhat curved 
above, nearly radial below, limbate on both surfaces, on the ventral side 
running into one another and merging at the umbilical area; wall smooth, 
finely punctate; aperture a slightly arched opening halfway between the 
umbilicus and the peripheral margin. 
Diameter of the Tortugas specimens up to 1.25 mm. 
This is a species which seems to be most at home in warm, shallow 
waters, such as are found in the Tortugas. Therefore it is not 
surprising to find that this is the most common species of the genus 
in the collection. Specimens were large and well developed, and in 
the last-formed chamber in the larger specimens there is a tendency 
somewhat to flatten out and to develop large apertures on the 
ventral face. The wall is thick and heavy and the sutures limbate. 
Pulvinulina semipunctata, new species.

chambers comparatively few, 7 to 10, rapidly increasing in size in the last-
