ammonoid family, Macrocephalitidae, discusses their biological relation- 
ships and their chronological significance. The next three papers, by Pro- 
fessor Edward W. Berry, describe the floras of the Kootenay, Blairmore, and 
Allison formations and discuss their correlations. The paper on Creta- 
ceous invertebrates describes some new species of pelecypods and a new 
variety of an ammonoid. The last paper is on stratigraphic palaeontology 
and describes the succession of faunas and floras, their relationship to the 
lithological succession, and discusses their correlation. A paper on the 
Jurassic pelecypoda was published in 1924. 1
