*A comparison of this form with the type species of Oonularl* 

 trentonensis, Hall, preserved in .the New York state museum, and 

 With typical material of Conularia hudsonia, Emmons, from the 

 Lorraine beds, proved that the Utica form, instead of approaching the 

 Lorraine species by greater coarseness of its sculpture, has, if any dif- 

 ferent sculpture, a rather closer and finer arrangement of the transversal 

 and longitudinal lines than even the Trenton form.
