Reophacidae 

 Reophax Denys de Montfort 

 R. DENTALiNiFORMis H. B. Brady. Found with the preceding- 

 species, abundant. 

 Station: D 150. 



R. piLULiFERA H. B. Brady. Also found with the preceding- 

 species. 



Station: D 150. 



Lituolidae 

 Haplophbagmoides Cushman 

 H. canariensis (d'Orbigny). In mud, depth 68 to 87 feet, 

 uncommon. 



Stations: D 19, 112. 



H. sciTULUs (H. B. Brady). On blue clay, depth 210 to 239 

 feet, common at D 150.

AmmobacuxiItes Cusliman 



A. cassis (Parker). In sand or arenaceous mud, depth 50 

 to 85 feet. Very common on the more sandy bottom at D 83, 

 but elsewhere rather rare. 



Stations : D 62, 76, 81, 83. 



Verneuilinidae 

 Verneuilina d'Orbigny 



V. advena Cushman. This pretty little species shows very 

 constantly the rust-brown color described by Cushman. It 

 is evidently due to darkening of the cement by age and may 

 be wanting in a newly formed chamber. 



In arenaceous mud and blue clay, shore to 210 feet, quite 

 common. The shore specimens are in clumps of Mytihis and 

 bryozoans. 



Stations : S 21, 48 ; D 19, 76, 150.
