Alleged “ bipolarity ” in distribution of marine animals. The theory of 
Theel, Murray, and Pfeifer is not sufficiently substantiated. In some 
cases, e.g., Decapod Crustaceans, it does not express the facts. The 
“bipolarity” has been exaggerated ; where it occurs it may be due to 
abyssal and littoral migration between the poles ; Ortmann (510). —
