182 PUSIA.

 examples, without locality, are also in the collection of the 

 Philadelphia Academy. 



T. SPRETA, A. Ad. PI. 54, fig. 555. 



Light yellowish brown. Length, *25 inch. 



A juvenile shell. It is not at all probable that it is distinct 

 from one of the previously described species : judging from tin-

 species, including the last. 



T. BOSEOCAUDATA, Hanley. PI. 54, fig. 556. 



Light yellowish brown. Length, '2 inch.
