8i4 CRETACEOUS PALEONTOLOGY. 



served in the collection of Columbia University, and judging 

 from its lithologic characters, it, too, is from the Navesink, rather 

 than from the Manasquan marl. Its characters are in no- way 

 essentially different from B. mortoni, and it may be safely con- 

 sidered as a synonym of that species. The species is here trans- 

 ferred from the genus Bulla to Haminea, because of the presence 

 of the revolving lines. 



Pormaiion and locality. — Navesink marl, Atlantic Highlands 

 (loS), near Crawfords Corner (126''), Crosswicks Creek (Whit- 

 field).
