REOPHAX SCORPIURIUS Montfort. 
Reophax scorpiurius Montrort, Conchyl. Syst., I, 1808, p. 330, 83d genre. 
This species has a universal distribution and bathymetric range. 
Its geological history goes back to the Oolite. Found at Stations 
H. 4508, H. 4567, and H. 4694, but not very common at any of the 
three.

HAPLOPHRAGMIUM AGGLUTINANS (d’Orbigny). 
Spirolina agglutinans D’ORBIGNY, Foram. Foss. Vien., 1846, p. 137, pl. vu, 
figs. 10-12. 
A cosmopolitan species and with correspondingly wide distribution 
in depth. Obtained only from Station D. 4174. 
HAPLOPHRAGMIUM CANARIENSE (d’Orbigny). 
Nonionina canariensis D’ORBIGNY, Foram. Canaries, 1839, p. 128, pl. 1, 
Kea, Bs, Gb 
Known from all oceans and at all depths. Found as a fossil but 
not earlier than the Pleistocene. Specimens obtained at Stations H. 
4566 and H. 4696 are rather more symmetrical and possess more 
chambers than some of the figured types of the species. The arena- 
ceous test, rounded periphery, depressed umbilici, and complanate 
character of the chambers are sufficient to distinguish this from alled 
forms. 
HAPLOPHRAGMIUM GLOBIGERINIFORME (Parker and Jones). 
Lituola nautiloidea globigeriniformis PARKER and JONES, Phil. Trans., CLV, 
1865, p. 407, pl. xv, figs 46, 47. 
This species is described with some doubt. There are only a few 
specimens, from Station 4585, which appear to belong here. They 
do not possess so many Globigerina-like segments and these are not 
so distinct, but the growth appears trochoid and the forms are con- 
ditionally placed here. Essentially a deep-water foraminifer of 
universal distribution. 
HAPLOPHRAGMIUM LATIDORSATUM (Bornemann). 
Nonionina latidorsata BoRNEMANN, Zeitschr. deutsch. geol. Gesell., VII, 
ISH, JO, S39), jo, Sx, wks, 46 GW, 
So abundant in the north deep sea explored by G. O. Sars that it is 
said to constitute one-fifth of the entire weight of the dredged ma- 
terial. While of universal distribution and more abundant in deep 
water, the form is also present in depths of 300 fathoms or less.
