Ill 



which it seems to have been confused. In general, the characteristic 

 feature of the species is the very large and flattened a])ical. orifice, 

 suggesting a shell normally possessed of a longer neck, a portion of 

 which has been accidentally broken off, leaving a somewhat wide and 

 jagged opening. In examining but one or two specimens the real 

 apical features would almost certainl}^ be overlooked, as the rim of 

 the a])ical orifice is generally chip]:)ed and more or less mjured. The 

 examination of many specimens under a glass soon suggests a certain 

 plan or design in the ajncal breaks. It finally becomes clearly appar- 

 ent that the uniformity in the mode of breakage is due to the pro- 

 jection of the four lobes already referred to.
