LAGENIDAE—POLYMORPHINA; UVIGERINA; SIPHOGENERINA. 35 
Genus SIPHOGENERINA Schlumberger, 1883. 
Siphogenerina advena, new species. 
(Plate 5, Figure 2.) 
Test elongate, somewhat compressed, early portion either triserial or 
biserial; later portion, which makes up the larger portion of the test, uniserial ; 
chambers numerous, distinct, inflated; sutures somewhat depressed, the 
early portion and a part of the uniserial portion with fine, longitudinal coste, 
more or less broken, followed by 2 or 3 chambers slightly spinose, after 
which the remaining chambers are smooth and very finely punctate; aperture 
elliptical, each one connecting with the preceding by an internal funnel- 
shaped tube. 
Length up to 0.65 mm. 
This is a very small, delicate species, but very characteristic and 
constant in form and ornamentation. It is unlike any of the de- 
scribed species and is probably characteristic of this general region, 
as it was found at a considerable number of stations in the area. 
Siphogenerina raphanus (Parker and Jones).

Siphogenerina costata Schlumberger, Feuille des Jeunes Naturalistes, ann. 13, 1883, p. 118, 
fig. 13. 
Test elongate, cylindrical, or tapering, chambers of the uniserial portion 
broader than long; surface marked by several rather widely separated, well- 
developed costz, each extending nearly the length of the test and not affected 
by the sutures; aperture typically with a short tubular neck and well-developed 
flaring lip. ; 
Length of the longest Tortugas specimens 1 mm. 
A single fine, large, typical specimen occurred at station 14 in 12 
fathoms, on the outside of the group off Loggerhead Key. There is 
another small, poorly developed specimen from station 28, in Bird 
Key Harbor, 4.75 fathoms. 
Family GLOBIGERINIDA. 
Genus GLOBIGERINA d’Orbigny, 1826. 
Globigerina bulloides d’Orbigny. 
Globigerina bulloides d’Orbigny, Ann. Sci. Nat., vol. 7, 1826, p. 277, No«1; Modéles, 1826, 
Oeste ates d’Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, 1839, “‘ Forami- 
niféres,”’ p. 83, pl. 4, figs. 15 to 18. 
This very widely spread species has occurred at only two stations 
in the bottom material of the Tortugas collection and was obtained 
very rarely in the surface tows made off Loggerhead Key. It is not 
nearly so common as the following species.
