FORAMINIFERA OF THE ATLANTIC OCEAN. 33 



from the Mediterranean, it is not recorded in any other region. I 

 have had specimens from the "Lord Bandon," from off Ban try Bay, 

 southwest of IreLand, in 37^ fathoms (70 meters), in material kindly 

 sent me by Mr. Joseph Wright. Specimens vary little in their 

 general character. This species was well figured by Williamson. It 

 has not occurred in any of the material I have seen from the western 

 Atlantic.

Description. — Test cuneate, broadening rapidly toward the aper- 

 tural end, the apical end small, blunt, much compressed, the edges 

 thin; chambers numerous, broad, and low, little inflated; sutures 

 very distinct but hardly depressed; wall smooth, punctate; aperture 

 elongate, narrow, ending at the edge of the inner border of the cham- 

 ber; color white. 



Length 0.3-0.6 mm. 



Distribution. — From the above references it will be seen that this 

 name has been used by many authors for both recent and fossil 

 specimens from about all the regions from which foraminifera have 

 been obtained. It has been used for all the flat, broad forms of the 

 genus. A comparison, however, of such specimens from different
