In the Quart. Journ. Geol. Soc, vol. xxxvi. 1880, p. 617, Mr. John B. Marr mentions having examined three specimens of a Phyllopodiform Crustacean discovered by Mr. Martin Dusl in the strata of “Colonie Haidinger,” situated not far from the village of Gross-chuchle, south of Prague.

The specimens were then identified with Discinocaris Browniana, H. Woodw., figured and described in the same Journal, vol. xxii. 1866, p. 503, pi. 25, figs. 4, 5, and 7. They are also mentioned by Dr. H. Woodward and Prof. T. Eupert Jones in the Third Eeport of the Committee on the Fossil Pliyllopoda of the Palaeozoic Eocks, 1885, p. 2, under Mr. Marr's specific determination.
