"One that beds members 1 and 2 are Heldentayian. the question arise what do beds 3,4,5 and 6 repre- sent in New York. It is probable that beds nos 1 and 2 are equal to the Creymans (possibly also Upper Mantlins) because of the predominance in them of Lepidula, Ferraris and Stromatopora. In this event beds 3-6 should be the equivalent of the New Zealand, Beeroff and Stimpson. The only difficulty in this correlation is that in Barke all the divisions are much thicker than those of New York, 2000 feet in the former against probably less than 500 feet in the latter area. The lithic nature of the beds in both areas is fairly alike and no difference in thickness can be ascribed to this cause. The Heldentayian of New York, Tennessee at the southwest have or many species not seen here in Barke that I am coming to the view that there is a migration from the south as well as one from the north-east. In the way of working out details of migrations much remains to be done. Mrs Binns and Kirkham of Montreal (in Quibbs by stry) are staying at the bars for a few days-.
