The Conns Dalli Toula is doubtless the young of imitator 

 described earlier in the same year by Brown and Pilsbry. Fig- 

 ure 6 is of a specimen from Mt. Hope which measures 51 by 25 

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

 plexing Cones, vt/hich probably should be referred to this speces. 

 From costaricensis the}' differ in tlieir nearly straight sides, more 

 irregular spiral groovingson the anterior canal, and they usually 

 show faint spirals over most of the bod3^-whorl, which I have 

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

 Comadre Creek near Cahuita, measures 65 by 29 mm.

This species is easily recognized by its well-rounded should- 

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