200 CRETACEOUS PALEONTOLOGY. 



Description. — "Test elongate, straight, tapering sharply; sur- 

 face smooth ; nine oval, regular chambers, rapidly increasing in 

 size toward the distal end ; primordial end acuminate ; ultimate 

 chamber globose, anteriorly prolonged into a distinct eccentric 

 tube; septa depressed, transverse; aperture nipple-shaped. 



"Length, 0.9 mm." (Bagg.) 



Remarks. — "The above species is very similar to Dentalina 

 subrecta Reuss, but the latter has fewer segments and the proximal 

 end less acuminate." (Bagg.) 



Formation and locality. — Vincentown limesand, Vincentown 

 (Bagg). 



Geographic distribution. — New Jersey.

Description. — "Test composed of six or seven short, oval cham- 

 bers, very strongly separated by septal constructions. The an- 

 terior portions of the ultimate chambers are smooth, but upon the 

 lower ends of these are two rows of spines or tubercles jutting out 

 at a low angle from the surface. Upon the primordial segments 

 these spines are found to cover the whole surface. Primordial 

 chamber armed with a short spine ; ultimate segment ending in a 

 tubular neck, which carries the round aperture.
