and rounded curving rather abruptly into the sutures above and 

 below. 



Remarks. The type of this species has the shell partially pre- 

 served, and from its lithologic character it apparently came from 

 the Navesink marl. The species occurs commonly in the Ripley 

 formation of the South in some localities, and many specimens are 

 preserved in the collections of the National Museum at Washing- 

 ton, with the shell perfectly preserved. The foregoing descrip- 

 tion has been taken largely from southern examples and two in- 

 dividuals have been illustrated. In New Jersey the species occurs 

 almost always in the form of internal casts in the Navesink marl. 

 These casts may be recognized by their rounded volutions, being 

 different in this respect from the similar casts of T. encrinoides 

 in which the larger volutions are distinctly quadrangular in cross- 

 section. 



Formation and locality. Navesink marl, Atlantic Highlands 

 (108), near Crawfords Corner (i26 7 ), Crosswicks Creek (147*, 

 149, 195), near Jacobstown (150), near Mount Laurel (166). 



Geographic distribution. New Jersey, Alabama.
