figs. 2-6. 

 Marginulina cnsis Flint (not Reuss, 184G), Rep. U. S. Nat. Mus., 1897 



(1899), p. 314, pi. 59, fig. 3. 



Description. — Test much elongate, subcylindrical, only slightly ta- 

 pering, often slightly curved, early portion somewhat compressed; 

 chambers close-coiled, later portion uncoiled, chambers inflated, dis- 

 tinct, the ventral side somewhat lobulate, dorsal side much less so; 

 sutures distinct, depressed; wall smooth, fairly thick; aperture ec- 

 centric, at the dorsal angle somewhat projecting, radiate. 



Length 2.50-4 mm. 



Distrihution. — This species was originally described by Baile}^ 

 from numerous stations southeast of Montauk Point, New York, to 

 southeast of Cape Henlopen where, he says, " This fine species is 

 one of the largest and most conspicuous forms in these soundings." 

 Flint's specimens were from three Albatross stations, one off the 

 Atlantic coast and about the latitude of New York, another off Cape 

 Hatteras, and the third in the Gulf of Mexico, depths ranging from 

 58-160 fathoms (106-293 meters). The first two of these stations 

 are in the area where this species occurs very abundantly. In the 

 Albatross material that I have examined this species has been very
