Description. — "Test large, elongated, complanate ; surface 

 smooth, marked by rather distinct septal lines, which separate 

 the narrow, extended, parallel chambers; greatest width near the 

 middle of the shell, thence tapering rather sharply toward both 

 extremities, but the lower portion slightly incurved, while the 

 anterior end is slightly outcurved, though not markedly so; pri- 

 mordial segment lost.

p. 50, pi. 3, fig. 6. 



Description. — "Test thin, leaf-like, broad at the center, but 

 tapering rapidly toward the oral end; consisting of 10 rather 

 narrow, elongated chambers, the surfaces of which are marked 

 transversely by numerous delicate costas, which run from septum

 eccentric, yet not enough toi justify its being placed among fla- 

 belline types. 



"Length, 0.&7 mm.; greatest breadth, 0.88 mm." (Bagg.) 



Remarks. — "This is one of the most beautiful of all frondi- 



cularians, and is at the same time exceedingly rare. We have 



only one specimen from the Lower Marl at Freehold, and it is 



interesting to note that Professor Reuss records the single occur-
