Thirteen of the twenty-two localities given in the Challenger re- 
port, where the above species is found, were in the South Pacific. 
Abundant at some stations and present at D. 4025, H. 4555, H. 4566, 
H. 4568, H. 4571, and H. 4585. The species is generally confined 
to shallow waters, but in one instance it was obtained at 1,900 fathoms 
in the South Atlantic. 
A. Goes considers this form only a variety of B. dilatata, but I 
believe it should be regarded as a distinct species. 
BOLIVINA SEMI-ALATA Bagg, new species. 
The nearest approach to this Foraminifer of which the writer has 
knowledge is Bolivina hantkeniana. The forms we have, however, 
are extremely narrow and stoutly built, with numerous chambers 
extending to nearly one-half the length of the shell. The ultimate 
chambers are exceedingly broadly expanded and widely keeled, the 
flange extending even over and around the aperture. ‘The lower 
end is acuminate. Two of these types were observed at Station H. 
4555. Theshell is large for the genus Bolivina. (See Plate V, fig. 3.)

More important from the fossil standpoint than any Bolivina 
unless perhaps B. punctata, and widely represented in existing seas. 
Its bathymetric range is also very extensive, but it is best developed 
on shallow bottoms. It is one of the best known Cretaceous Loli- 
vinas. Found at Stations H. 4017, fine examples at H. 4025, also 
present at H. 4430, H. 4440, H. 4508, H. 4566, H. 4568, H. 4585, 
H. 4694, and H. 4696. 
Subfamily CASSIDU LININ AX. 
Genus CASSIDULINA. 
CASSIDULINA CRASSA d’Orbigny. 
Cassidulina crassa D’ORBIGNy, Foram. Amer. Merid., 1839, p. 56, pl. vit, 
figs. 18-20. 
Synonymous with Cassidulina oblonga Reuss. Characterized by 
its obtuse periphery, oval outline, and small number of short inflated 
segments, which distinguishes the species from C. laevigata. | 
Common over wide areas in the North Atlantic and at depths as 
great as 2,760 fathoms. A long list of localities given by Professor
