its geological history dating from the chalk beds of the Cretaceous. 
Present most commonly of all the Lagena noted at Stations D. 4017, 
D. 4174, H. 4480, and H. 4696. 
LAGENA QUADRATA (Williamson). 
Entosolenia marginata quadrata WILLIAMSON, Recent Foram. Gt. Brit- 
Aili, UKs,  IOL, ol, m iss, Br, BS, 
Present in various localities in both Atlantic and Pacific, but al- 
ways at depths of less than 150 fathoms. Known in the Miocene of 
Italy and the Post-Tertiary of Ireland. Occurs at Albatross Sta- 
tions H. 4440 and H. 4694. 
LAGENA STRIATA (d’Orbigny). 
Oolina striata D’ORBIGNY, Foram. Amer. Merid., 1839, p. 21, pl. v, fig. 12. 
An oval, frequently bottle-shaped Lagena with elongated tubular 
neck and striate surface. Of world-wide distribution the form is 
found equally with Lagena sulcata, which it resembles, but the species 
belongs to shallow waters. It is present in the Septaria clays of 
Germany and in the Miocene elsewhere. Noted at three stations, 
H. 4566, H. 4567, and H. 4694.

NODOSARIA CALOMORPHA Reuss. 
Nodosaria calomorpha Reuss, Denkschr. Akad. Wiss. Wien, XXV, 1865, 
p. 129, pl. 1, figs! 15—19. 
One of the simplest smooth Vodosarie and of only two or three seg- 
ments. North and South Atlantic, South Pacific, and elsewhere in 
off-shore deposits at less than 100 fathoms. Reported, however, at 
depths of over 2,000 fathoms. Fossil in the Septaria clay of North 
Germany. Station H. 4508, rare. 
NODOSARIA COMMUNIS (d’Orbigny). 
Dentalina communis DdD’ORBIGNY, Mem. Soc. Geol. France, IV, 1840, p. 18, 
pl. 1, fig. 4. , 
Smooth surface, oblique septa, and slender build are the three 
leading characteristics of the species. The synonomy as at present 
understood and published in monographs on Foraminifera is very 
extensive. As a recent Foraminifer it has a universal distribution. 
Its geological history dates from the beginning of the Mesozoic. 
The most common nodosarian in the material examined, and present 
at Stations D. 4000, D. 4025, H. 4480, and H. 4566. The specimens 
obtained are most excellent representatives.
