VIRGULINA SQUAMOSA STRIATA Bagg, new subspecies. 
Similar to the well-known species Virgulina squamosa, but dis- 
tinctly striated. (See Plate V, fig. 7.) : 
Type.—Cat. No. 8202, U.S.N.M., Station D. 4025, depth 275 to 
368 fathoms. 
Genus BOLIVINA. 
BOLIVINA ENARIENSIS (Costa). 
Brizalina enariensis Costa, Atti dell’ Acecad. Pontin., VII, 1856, p. 297, pl. 
LW, IMSS Ik, Gy, De 
This neatly tapering, striate Bolivina, with or without its spinous 
aboral end, is cosmopolitan, and we found it at Stations D. 4174, 
H. 4440, H. 4502, H. 4508, H. 4555, H. 4567, H. 4571, H. 4585, and 
H. 4696. 
Best developed types come from the North Atlantic Ocean at 
depths of a few fathoms down to 1,630 fathoms. Professor Brady 
records the species from off the Philippines at 95 fathoms, off the 
south coast of Japan at 15 fathoms, and the La Plata River, South 
America, at 13 fathoms. It occurs as a fossil in the Tertiary beds of 
the island of Ischia. 
BOLIVINA DILATATA Reuss. 
Bolivina dilatata Reuss, Denkschr. Akad. Wiss. Wien, I, 1849, p. 381, pl. 
SONG, Toe, IL), 
The test of Bolivina dilatata is broad, depressed, composed of 
numerous long narrow chambers and possessing an acute periphery. 
Prof. H. B. Brady states that the species is confined to the North 
Atlantic, but we find it present, and in some cases abundant, at nearly 
every station studied. These are: D. 4017, D. 4025, D. 4174, H. 4430, 
H. 4502, H..4508, H. 4555, H. 4568, H. 4571, H. 4694, and H. 4696. 
The average depth is below 400 fathoms. The geological occurrence 
dates from the Cretaceous. 
BOLIVINA HANTKENIANA Brady. 
Bolivina hantkeniana Brapy, Quart. Journ. Microse. Sei., X XI, n. s., 1881, 
p. 58. 
Test depressed and nearly equally convex on each surface, con- 
sisting of numerous broad inflated segments arranged alternately and 
provided at their margin with a delicate keel. The surface is usually 
faintly striate. Probably limited in distribution to islands of the 
Pacific. Present at Station D. 4017, fine specimens at H. 4440, also 
found at H. 4555 and H. 4585. The depths at which the form is 
recorded vary from 130 to 800 fathoms. Not recorded as a fossil.
