 ton group.) Emmons' American Geol- 

 ogy, Vol. I, part 2, page 207, plate 16, 

 figs. 7 <^, 7 h ; slightly arcuate ; surface 

 marked with deep wavy cross lines; the 

 lines lengthwise rather indistinct. All 

 the Gonularias are pyramidal pteropods, 

 with delicate texture " like a woven 

 fabric;" solid top (apex), "separated 

 from the open shell above by a simple 

 imperforate very convex septune." Em- 

 mons refers to a specimen in his collec-

 rare as compared with the abundant C. trentonensis^ and that 

 its shell seems very thin and fragile.

 stronger than in C. trent.^ and
