Description.—Shell having the form of a gradually-tapering, more 
or less curved or flexuose, annulated cone. On the internal casts the 
annulations have the aspect of insheathed cones, the slope being abrupt © 
below and gradual above. ‘The width of the annulations is variable, 
but is usually a little less than one millemeter; they are somewhat 
irregular, there occasionally being one which does not entirely sur- 
round the tube. 
The dimensions of the best specimen observed, which is nearly 
straight and incomplete at its smaller extremity, are: length, 14.5 
mm.; diameter at larger end, 4.5; diameter at smaller end, 3 mm. 
Remarks.—The New Jersey specimens of this species are from the 
higher beds of the Coeymans hmestone near Hainesville. They agree 
more closely with Clarke’s figures of the species from the Oriskany 
beds than with Hall’s original figures.
