Of the many private collections of vertebrate fossils found on or off the coast of the Eastern counties, none surpass in palæontological and also in geological interest the fine collection made with much zeal and care by Mr. J. J. Owles, of Yarmouth, inasmuch as the larger portion of the specimens are exclusively the remains of Postglacial Mammals, and were brought up in the fishermen’s dredge, either from, or in close proximity to the well-known Dogger Bank, thus proving conclusively the existence of submerged Pleistocene or Postglacial land lying off the Eastern coast in the North Sea. Prof. Boyd Dawkins is the only author, as far as I am at present aware, who has made any reference to this really valuable series of remains, and then only incidentally in his memoir, “On the Distribution of Postglacial Mammals.”
