interesting to know the exact character of Chapman's specimens 

 from very deep water off Funafuti in 2,107 and 2,715 fathoms (3,854 

 and 4,966 meters.^' 



Goes records the species from the Caribbean,^^ but his specimens are 

 not available and it is doubtful just what he had from his figures. 

 Egger's figures ^* certainly do not represent this species. 



Whatever may be the case elsewhere, certainly in the North At- 

 lantic, off both the eastern and western coasts, typical Cassidulina 

 bradyi is well-developed and very constant and well defined in its 

 characters.

CASSIDULINA BRAZILIENSIS. new species. 



Plate 25, figs. 4, 5. 



Description. — Test elongate, compressed, curved, early portion 

 close-coiled, later portion loosely coiled, periphery much curved 

 throughout; chambers comparatively few, slightly inflated, very 

 distinct; wall thin and translucent, very finely perforate, smooth; 

 sutures very clear and distinct, slightly depressed; aperture slightly 

 elongate, comma-shaped, color whitish. 



Length, 0.35-0.40 mm. 



Distribution. — Type-specimen (U.S.N.M. No. 16387) from Alba- 

 tross station D2756, off the coast of Brazil, 417 fathoms (763 meters). 

 At this station several specimens were found, all of one general 

 character. It has a peculiar curved test, differing from C. bradyi in 

 form, as the later chambers are not entirely uncoiled, are more dis- 

 tinct, and the walls are thin and translucent. This has not been 

 found elsewhere in the Atlantic material I have examined and may 

 be peculiar to this region.
