Fig. 10. 



Description. — Elongate ; apical angle about 20° ; whorls five 

 or six ; depressed convex, or nearly flat in the middle ; length, 

 four or five inches ; width of body whorl about fifteen lines. Each 

 whorl is about one-third shorter than the one preceding it. 



This species, in its form and in the proportional length of the 

 whorls, very closely resembles a species that occurs in the Trenton* 



It appears to be more like a Loxonema than a JSubulites. 



Locatity and formation. — Mingan Islands, Calciferous sandrock. 



Collectors. — Sir W. E. Logan, J. Richardson.
