When Prof. Cragin first announced the occurrence of Ostrea 
Jrankiini and the Trinity sands in Kansas—before giving the 
paleontologic details since published—the writer was inclined 
to accept his conclusions.* But as Prof. Cragin’s paleontologic 
publications progressed, it became my opinion, even without 
having seen the region, that the Belvidere beds of Kansas 
represented the writer’s upper or Washita division of the 
Lower Cretaceous section, and not entirely the Fredericks- 
burg and Trinity as asserted by Cragin. This opinion was 
confirmed after seeing, later, Prof. Cragin’s collections at 
Washburn College. 
If distantly situated beds are to be correlated by the law of 
common species, it is impossible to see upon what ground Prof. 
Cragin referred these beds entirely to the Trinity and Fredericks-
