2§. Latest Additions to our Knowledge of the Lower Palæozoic Phyllopoda

(Phyllocarida).

There has not been much to notice additional in the study of Paleozoic Phyllopoda since the last (Eleventh) Report in 1894.

1. Professor Dr. Gustav Lindström, paleontologist in the State Museum of Sweden, has discovered and courteously sent to us specimens of a new Emmelozoe, not far removed in shape and features from E. elliptica (M'Coy). Several very definite individuals, with delicate, thin, shining carapace-valves, light brown, and somewhat iridescent, occur

in a bluish-grey marly shale from Lau in Gothland, corresponding with the Wenlock Shale of England. They will be figured and described in the 'Geological Magazine' before long as Emmelozoe Lindstroemi.

2. In the 'Sitzungsberichte königl. Böhmisch Gesellsch. Wiss., Math.nat. Cl.' for 1894, article xxxvi. (separate copy dated 1894), Professor Dr. Anton Fritsch, in a preliminary report on the Arthropoda and Mollusca of the Permian formation in Bohemia, enumerates five species of Estheria, partly noticed in our Tenth Report, 1893, namely, (1) Estheria triangularis, Fr. (=? E. tenella in his 'Fauna der Gaskohle,' vol. i., p. 31), with remains of the animal, from the Gas-coal of Nyřan; (2) E. cyanea, Fr., from the Black-coal of Kounová; (3) E. palæoniscorum, Fr., covering whole beds in the Brandschiefer (Carbonaceous Shale) of Koštialov; some individuals show the large antennæ ; (4) E. calcarea, Fr., related to E. minuta; rare, in the red Plattenkalk of the Braunau district; (5) E. ultima, Fr., in the uppermost part of the limestone with Amblypterus Feistmanteli, near Vitouchov, not far from Lomnitz. There are also Candona elongata, Goldenberg, from the red limestone of Křečowic, near Rowensko (Turnau); and Carbonia Salteriana, Jones and Kirkby, in the red limestone of Stradonic, near Peruc; and Cythere, sp., in the red limestone of Klobuk, near Schlan.

Erratic Blocks of England, Wales, and Ireland.-Twenty-second Report of the Committee, consisting of Professors E. HULL (Chairman), J. PRESTWICH, W. BOYD DAWKINS, T. McK. HUGHES, T. G. BONNEY, Messrs. C. E. DE RANCE, P. F. KENDALL (Secretary), R. H. TIDDEMAN, J. W. WOODALL, and Prof. L. C. MIALL. (Drawn up by the Secretary.)

[Read at Oxford, 1894.]

THE investigations of the Committee during the past year have yielded results of more than ordinary interest, though the amount of information to be embodied in their report is less than has been available during the previous two or three years.

A hope was expressed in the twenty-first Report that, as the result of an appeal made to the Corresponding Societies, information would be forthcoming regarding the Erratic Blocks of districts from which hitherto no returns had been sent in. This expectation has been realised; and the Committee, for the first time in their history, are now enabled to justify the reference to Ireland in the terms of their appointment. In response to the circular issued by this Committee to the Corresponding Societies, the Belfast Naturalists' Field Club promptly organised a committee to investigate the Erratic Blocks of the north-east of Ireland; and the first report, drawn up by the Honorary Secretary, Miss Sydney M. Thompson, and printed in the Proceedings of the Club (1893-94), is a valuable record of minute painstaking and accurate investigation. The Committee have not limited their work to merely recording the erratics, but have made a complete study of the Drift deposits, and their organic and other contents, at several selected exposures, and have transmitted to this Committee a series of twenty photographs illustrating the features described. Lincolnshire is also added to the list of English counties coming within the sphere of the actual operations of the Com
