46 SHALLOW-WATER FORAMINIFERA OF TORTUGAS REGION. 
The original figures of this species given by d’Orbigny show an 
irregularly spiral test not unlike that figured in the Cuban mono- 
graph as P. vulgaris. The specimens, however, are not so regular 
as that figured by d’Orbigny. However, the specimens here figured 
show a distinct spiral tendency that is evidently not the same as 
the one referred here to P. acervalis. Such specimens are similar to 
the figure given by Goés (Kongl. Svensk. Vet. Akad. Handl., vol. 
19, No. 4, 1882, plate 97, fig. 227), which he referred in 1896 to P. 
mediterranensis instead of P. farcta var. vulgaris, the name used in 
1882. This species is far less common than P. acervalis in the 
region, occurring at but one station, and then rarely.

Test biconvex, trochoid, dorsal side much convex, ventral side less so; 
chambers numerous, about 9 or 10 in the last-formed whorl, coarsely punctate; 
sutures somewhat limbate, oblique on the dorsal side, radiate on the ventral 
side, forming a central boss following the umbilicus; sutures not depressed, 
except on the ventral side, the spire of the dorsal side often ornamented with 
rows of beads projecting above the general surface, in some specimens rising 
considerably above the surface of the test; the aperture an elongate slit at the 
inner margin of the ventral side of the last-formed chamber, with a con- 
siderable lip developed above it; color a beautiful rose-red, especially i in the 
earlier portion, but usually in live specimens present throughout the test. 
Diameter of the Tortugas specimens up to 0.55 mm. 
This species seems to be peculiar to the West Indian region, except 
for a record I have given for it from Woods Hole. 
Egger, in 1893 (Abh. kén. bay. Akad. Wiss. Miinchen, Cl. II, 
vol. 18, p. 397, pl. 16, figs. 4 to 6), recorded 7’. rosea from off West 
Australia, but, except for the reddish color, little in his description 
suggests this species, and his figures show something entirely different 
from this definite West Indian species. 
Heron-Allen and Earland (Trans. Zool. Soc. London, vol. 20, 1915, 
p. 708) record this species also, in the following words: 
““A few typical specimens of this species, one of the few Foraminifera 
characterized by pink coloration, and hitherto, with the exception of a 
Gazelle record from West Australia, known exclusively from the West Indian 
seas. The Kerimba specimens resemble Egger’s figure more closely than 
d’Orbigny’s Modéle, having a somewhat more depressed shell.”
