Although I have never seen a T. angutatus with distinct epitheca 

 and expanded base, yet, judging from the analogy of T. conulus, it 



is reasonable to suppose that they were originally present : indeed 

 it is exceedingly rare to find even a trace of the costnlate wall, their 

 usual condition being that of dark phosphate casts.
