FOEAMINIFERA OF THE ATLANTIC OCEAN 83 



There are only a tew records for the species in the Atlantic, although 

 it was described by Brady from the Faroe Channel and no other local- 

 ity given in the Challenger report. Since then it has been recorded as 

 abundant as a recent and fossil species in the Austrahan region and 

 elsewhere in the Pacific.

Test close-coiled, not flaring, coils increasing regularly in diameter; 

 tube somewhat compressed laterally, the sides convex, peripheral 

 margin with a thin but sharply defined keel; surface smooth except 

 for occasional depressions marking the lines of growth; aperture 

 broadly elliptical. 



Diameter up to 3 millimeters. 



This is not a common species but it seems to be widely distributed. 

 There are numerous records from off the British Isles and the west- 

 ern coasts of Europe. Flint's specimens are from the Gulf of Mexico 

 and off the northeastern coast of the United States. 



CORNUSPIRA ANGIGYRA (Reuss) 



Under this name Heron- Allen and Earland place a single recent 

 specimen from dredgings west of Scotland. ^^ This is apparently the 

 only record for the species in the present ocean. Reuss described 

 the species from the Oligocene of Germany. 



CORNUSPIRA (?) DISCUS (Egger)

11, vol. 18, 1893, p, 217, pl. 1, figs. 50, 51. 



Egger records this pecuUar Uttle species as rare from 677 meters 

 off the West Coast of Africa. From an examination of the type in 

 Munich, this seems to be possibly a Cornuspira.
