TRUNCATULINA LOBATULA (Walker and Jacob). 
j 
Nautilus lobatulus WALKER and JAcos, Adam’s Essays, Kanmacher’s ed., 
1798, p. 642, pl. xiv, fig. 36. 
One of the most widely diffused Rotaline types known and occur- 
ring frequently in all formations where Foraminifera are present 
from the Carboniferous to Recent. Found at all stations except H. 
4430, H. 4502, H. 4555, H. 4566, H. 4579, H. 4585, and H. 4590.

The authors state that this form, common at 260 fathoms off the 
Abrohlos Bank, South America, is intermediate between Zruncatu- 
lina hadingervi and Truncatulina ungeriana. Yt is more compressed 
than the former, with about double.as many chambers in each con- 
volution, and they consider Pulvinulina karstent its nearest isomorph. 
Specimens agreeing closely with the description and figure of this 
species -we find at Station D. 4000, depth 104 to 213 fathoms. 
TRUNCATULINA PRAKCINCTA (Karrer).

Of this coral reef species no typical representatives occur in the 
Albatross collections, but what perhaps is a variety of the form 
occurs rarely at Station H. 4476. 
TRUNCATULINA PYGMEA Hantken.

This is a very deep-water species, being found at depths of 1,570 
to 3,125 fathoms. Represented at Station H. 4502, 1,342 fathoms. 
TRUNCATULINA REFULGENS (Montfort). 
Cibicides refulgens MontFort, Conechl. System., I, 1808, p. 122, 31 genre. 
Truncatulina refulgens occurs at depths ranging from about 50 to 
2,500 fathoms and is typically represented in the temperate-zonal 
waters outside the Tropics. Found rather unfrequently at Stations 
D. 4000, D. 4174, H. 4430, H. 4476, H. 4566, and H. 4696. It is a well- 
known fossil from the Cretaceous and later formations.
