GEOLOGY.—The late Searles V. Wood states, at p. 198 and again in the Synoptical List at p. 203 of his Supplement to the Crag Mollusca, that Cassidaria bicatenata, Sow., does not occur at Walton-on-Naze. As he attaches certain significance to its absence from this locality, it is obviously advisable to place upon record the fact that I found a specimen of C. bicatenata there in April 1926. It happened to be in poor condition, very defective about the lip, and of the thicktness of blotting-paper. I f the shell had not been tightly packed with sand and comminuted shells, it must long ago have disintegrated beyond recognition, except by such an expert as Mr. Wood.—C. G. DOUGHTY ; August 1935.

Society on 23 January last Sir A. Smith Woodward thought that the theory of Continental Drift helped to explain the known distribution of ea/ly land faunas. However, so many instances of nearlv parallel evolution had now been recognized by Palasontologists that the evidence of fossils needed careful examination before used to indicate former land connexions. For example, the horned Tortoise, Miolania, of the Australian region was so similar to Niolamia from Patagonia that these two fossils might be supposed to prove the former existence of an antarctic continent, uniting Australia and South America [the same may be said, also, of their Insects] ; but they were only extreme foims of a Chelonian suborder which was almost universally distributed in past ages, and therefore they might have onginated independently. T h e little Mesosauria, found in the PERMIAN of Brazil, seemed to be so essentially identical with those
