asper is common to all, but by eating out the Streptelasmas with acid and 
by sectioning them when possible it is seen that they are specifically different. 
It is also evident that the genus Halysites is not capable of such a broad 
interpretation in correlation as has been attached to it. Although a good 
many specimens have been sectioned not one has shown the proportions 
of the Manitoba species Halysites gracilis. So that, although in a broad 
sense the fauna is allied to that of Manitoba and Wyoming the differences 
are greater than they have been generally considered.
