Antarctic hydrographic fluctuation as suggested by animals that reach Ceylon
Various records of antarctic and southern cold temperate zone species entering the Ceylon area appear in the Colombo Museum bulletin Spolia Zeylanica , in the check list of the birds of Ceylon, and in the administration reports of the Marine Biologist of Ceylon. A study of these data reveals that fl...
