The Conns Dalli Toula is doubtless the young of imitator 

 described earlier in the same 3^ear by Brown and Pilsbry. Fig- 

 ure 6 is of a specimen from Mt. Hope which measures 51 b\' 25 

 mm. From Costa Rica, the collection contains a series of per- 

 plexing Cones, which probably should be referred to this speces. 

 From costaricensis they differ in their nearlj^ straight sides, more 

 irregular spiral groovings on the anterior canal, and they usually 

 show faint spirals over most of the body-whorl, which I have 

 not observed on costaricensis. A large shell from Zone C of 

 Comadre Creek near Cahuita, measures 65 by 29 mm.

This species is easih^ recognized by its well-rounded should- 

 er and appressed sutures. It is closely related to the recent C.
