Genus FRONDICULARIA. 
FRONDICULARIA ROBUSTA Brady. 
Frondicularia robusta Brapy, Chal. Rept., LX, p, 523, pl. uxvi, figs. 1, 2. 
This is the only species of the genus /rondicularia noted in the 
stations dredged and it is rare at Station 4508. Professor Brady ob- 
served it at only two localities, one near Ki Islands, 129 fathoms, 
the other on the coral reefs of the Hawatian Islands, 40 fathoms. 
The form is characterized by its robust test, with surface strongly 
costate, but less regularly so than in NVodosarie. 
Genus RHABDOGONIUM. 
RHABDOGONIUM MINUTUM Reuss. 
Rhabdogonium minutum Reuss, Sitzungsber. Akad. Wiss. Wien, LV, 1867, 
p. 84, pl. v, figs. 4, 5. 
The only specimens of this species dredged by the Challenger came 
from off Ki Islands at a depth of 129 fathoms. ‘The form was noted 
rather frequently at Stations D. 4000, H. 4480, Hl. 4508, H. 4555, 
H. 4695, and H. 4696. 
RHABDOGONIUM TRICARINATUM (d’Orbigny). 
Vaginulina tricarinatum D’ORBIGNY, Ann. Sci. Nat., VII, No. 4, 1826, p. 
258, modele, No. 4. 
Rhabdogonium tricarinatum has a wide distribution in the fossil 
world and is frequently recorded in Tertiary strata. A variety of 
this form (acutangulum) is known in the Lower Cretaceous. In hv- 
ing condition the form is met with in the North Atlantic from shoal 
water down to over 1,300 fathoms. It comes also from the Mediter- 
ranean and the Pacific, and is very abundant in the Albatross dredg- 
ings, being found in all stations except H. 4476, H. 4502, H. 4567, 
Hi. 4579, and H. 4590. 
Genus VAGINULINA. 
VAGINULINA LEGUMEN (Linnzus). 
Nautilus legumen LINN&US, Syst. Nat., 10th ed., 1758, p. 711; 12th ed., 
UCGE, Jo Iau 
A cosmopolitan form with universal distribution and at all depths 
found sparingly. Has a long geological history and is known at 
least as early as the Trias. In later formations it becomes more fre- 
quent and I have recorded it from the New Jersey Cretaceous, where 
it is by no means rare. Found at Stations D, 4174 and 4567,
