E P I G R U S, gen. nov. 



A genus of the Rissoidcc, allied to Scrobs. Shell tall, slender, 

 smooth, cylindrical. Aperture oblique, appressed ; apex large, 

 often protuberant. 



Type : liissoa ischna, Tate = Rissoina cylindracea, T. Woods. 



Other species are E. dissimilis, Watson, E. xanthias, Watson, 

 E. petterdi. Brazier, E. verconis, Tate, and E. simsoni, Tate & 

 May. This genus has puzzled all writers that encountered it. 

 Tenison Woods placed my type with hesitation in Rissoina. Boog 

 Watson referred my second species with serious doubt to Eid-ima, 

 my third to Jlfnc'ronalia, and Petterd assigned my fourth to 

 Rissoa. Such want of harmony sufficiently indicates the need 

 felt for the introduction of this genus.
