22 SHALLOW-WATER FORAMINIFERA OF TORTUGAS REGION. 
There is a tendency to strengthen the very thin test by the build- 
ing of supporting interior walls. In this specimen there is usually 
a single long wall across the chamber, with secondary ones at the 
sides, but on the final chamber there are at least two long walls, 
besides the supplementary ones. The spicular bodies are rather 
uniform in size, on the ventral side running more or less parallel 
to the margin, while on the dorsal side they are more nearly radial. 
The aperture is small, at the ventral border of the chamber, and has 
a slight projecting lip above it, of about the width of two of the 
spicular bodies. Our specimen is very nearly free from any foreign 
material, the spicules being neatly cemented and forming practically 
the entire wall of the test. 
This is one of the interesting finds of the collection, giving an 
Atlantic record for this hitherto Pacific species. It is unknown in 
a fossil condition, and is now known from the Pacific from Funafuti 
(Chapman), the Malay region (Millett), the South Pacific and the 
Gulf of Manaar (Carter), the Gulf of Suez (Brady), the Kerimba 
Archipelago off southeastern Africa (Heron-Allen and Earland), and 
the Mediterranean (Sidebottom).

Textularia agglutinans d’Orbigny. 
(Plate 1, Figure 6.) 
Textularia agglutinans d’Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, 1839, ‘‘ Foramin- 
iféres,”’ p. 136, pl. 1, figs. 17, 18, 32 to 34.—Cushman, Proc. U. S. Nat. Mus., 
vol. 59, 1921, p. 49, pl. 11, figs. 1 to 3. 
Test elongate, tapering from the subacute base to the broadly rounded 
aperteral end; chambers numerous, inflated; sutures depressed; in side view 
chambers wider than high; wall arenaceous, but rather smoothly finished; 
aperture an elongate, somewhat arched, opening at the inner margin at the 
base of the last-formed chamber; color white. 
Length of the Tortugas specimens up to 1 mm. 
Textularia agglutinans has occurred at nearly all the Tortugas 
stations, usually in considerable numbers. There seem to be two 
forms of this species—a microspheric form in which the total length 
is greater and the early development commencing with smaller 
chambers, so that the initial end is pointed and tapering, and a 
megalospheric form which is more bluntly pointed at the end, not 
nearly so tapering, shorter, and of fewer chambers. D’Orbigny’s 
specimens were much like those shown in plate 1, figure 6. He 
gives 1 mm. as the length of these specimens. They were from 
Cuba, St. Thomas, Martinique, and Jamaica. I have already 
recorded the species from shallow water from the north coast of 
Jamaica, and it is doubtless common in such habitats in the Gulf 
of Mexico and the Caribbean region.
