68 SHALLOW-WATER FORAMINIFERA OF TORTUGAS REGION. 
As I have already noted in a previous paper, Q. tricarinata seems 
related to Q. kerimbatica (Heron-Allen and Earland), which they 
described from the east coast of Africa. D’Orbigny’s specimens 
were from Cuba and Jamaica, and I found specimens which could 
be referred to this species in the collection from the north coast of 
Jamaica. Specimens apparently either identical or closely allied to 
this occur in the Tertiary of Santo Domingo. 
Quinqueloculina cf. Q. kerimbatica Heron-Allen and Earland var. philippinensis Cushman. 
From 3 stations there are a few specimens which in their general 
character of ornamentation resemble a variety I have described from 
the Philippines (Bull. 100, U. S. Nat. Mus., vol. 4, 1921, p. 438, 
plate 89, figs. 2,3). They have a reticulate periphery on each cham- 
ber, but the sides are smooth and unornamented. 
Quinqueloculina parkeri (H. B. Brady) var. occidentalis Cushman.

Quinqueloculina parkeri (H. B. Brady) var. occidentalis Cushman, Proc. U. S. Nat. Mus., 
vol. 59, 1921, p. 69. 
Test differing from the typical in the great number of fine, transverse or 
slightly oblique ridges or crenulations, and the tendency for the chambers to 
become squarely truncate or even tricarinate. 
Length of the Tortugas specimens up to 0.60 mm. 
This variety, which I described from the north coast of Jamaica, 
occurs also in the Tortugas collections, but israre. It does not reach 
so large a size as the typical form, and the ornamentation differs also. 
Quinqueloculina polygona d’Orbigny. 
Quinqueloculina polygona d’Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, 1839, 
“Foraminiféres,’’ p. 198, pl. 12, figs. 21 to 23. 
Test somewhat longer than broad; chambers distinct; sutures slightly de- 
pressed; each chamber polygonal in cross-section, the periphery usually con- 
cave, with a projecting carina at either angle; apertural end extending into 
a short, cylindrical neck, aperture circular with an everted lip, and a single 
bifid tooth; surface usually dull. 
Length of the largest Tortugas specimens 0.75 mm. 
This species was originally described by d’Orbigny in Jamaica 
and Cuba, and both in the material I have had from the north coast 
of Jamaica and this lot of bottom samples from the Tortugas it is 
common and in the same form as that described and figured by d’Or- 
bigny. It is evidently a species of wide distribution in the West 
Indian region. Brady places Q. polygona as a synonym of Q. ferus- 
sacii d’Orbigny, but if the original figures of these two species as 
given by d’Orbigny are compared they seem to have little in common, 
and it seems as though Q. polygona was a well-characterized species 
in this region.
