Subfamily HAU HRININ A. 
Genus VERTEBRALINA. 
VERTEBRALINA INSIGNIS Brady. 
Vertebralina insignis Brapvy, Chal. Rept., EX, 1884, p. 187, pl. x11, figs. 9-11. 
This rare species is known from off the Friendly Islands, 15 
fathoms, in Torres Strait, 195 fathoms, and off the West Indies, 390 
fathoms. Occurs at Station H. 4694 at a depth of 865 fathoms, which 
is its deepest recorded occurrence. 
Subfamily PHNHEROPLIDIN 44. 
Genus CORNUSPIRA. 
CORNUSPIRA FOLIACEA (Philippi). 
Orbis foliaceus PHILIPPI, Enum. Moll. Sicil., II, 1844, p. 147, pl. xxiv, fig. 26. 
Test planospiral, with thin, flat, rapidly widening whorls, and 
while the surface has no decoration there are frequently curved 
transverse lines of growth as in many of the Gasteropoda. An allied 
form with carinate margin is Cornuspira carinata (Costa). 
Rare in Scandinavian waters and Greenland (Goes), not uncom- 
mon in the Pacific, and ranging from shallow depths down to about 
1,500 fathoms. Professor Brady states that the best specimens come 
from depths between 300 and 600 fathoms. 
Present in the Eocene and later Tertiary. Recognized at Station 
D. 4017 only, but is not common. 
CORNUSPIRA INVOLVENS Reuss. 
Cornuspira involvens Reuss, Sitzungb. Akad. Wiss. Wien, XLVIII, 1863 
(ASKS), JP. IL, JO SY, WL m, ike, B 
Recognized by its rounded tubular whorls, which closely embrace 
each other and yet allow each whorl to be seen on either surface. 
Geological history from Tertiary to recent. Has probably been 
confused with Jurassic and Cretaceous Ammodisci, which it resem- 
bles. Dr. A. Goes records the form in the Arctic and Norwegian 
waters at depths ranging from 30 to 180 meters. <A shallow water 
cosmopolitan species. Observed at Stations D. 4017 and D, 4174.

PENEROPLIS PERTUSUS (Forskal). 
Nautilus pertusus ForsKat, Descr. Anim., 1775, No. 65, p. 125. 
The genus Peneroplis, like Orbiculina, represents great variety of 
form and degree of compression and elongation of chambers without 
altering the segment arrangement or method of growth. For this 
reason and because of the transitional forms, it becomes necessary to 
separate the genus into several distinct types around which must
