are also a few species which are probably derived from the lower beds 

 ■of the Tertiary." 



Specimens which appear to differ from those from the East Fork of 

 MiUv Eiver only in being a little smaller, have since been colleclod at 

 the following localities. St. Mary Eiver, eleven miles above its mouth, 

 <x. M. Dawson, 18S1 ; and Belly Eiver, near the St. Mary Eiver, E. G. 

 XcConnell, 1881. South Saskatchewan, opposite Swift Current Crec^k, 

 E. G. McConnell, 1882 ; and Lorne Grossing of the Eed Deer Eiver, 

 Section 2-1, Township 25, Eange 16, west of 4th Principal Meridian, 

 J. B. Tyrrell, 1884. None of the specimens from these loc-alities, 

 however, shew the sep)tation and hence there may be a donbt whether 

 they are correctly referred to B. grandis or not, but tliey seem to ilitfiT 

 from the Baculites here referred to B. compressus in being thicker later- 

 ally, in having the antisiphonal side distinctly flattened, and in being 

 marked by coarse and distant transverse undulations.

 figure 2a of S. abyssinus on plate 35 of his " Eeport on the Invertebrate 

 Cretaceous and Tertiary Fossils of the Upper Missouri country, in
