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, palæontologist 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

mittee, and it is matter for congratulation that two observers have undertaken the work of recording the erratics of that county Two very important pieces of work have been undertaken by the Yorkshire Boulder Committee, one in the western portion of the area coming within their purview, near Barnsley, and the other, by the aid of the East Riding Boulder Committee, organised under the secretaryship of Mr. J. W. Stather, F.G.S., by the Hull Geological Society, in the country round Hull. In the latter case an exhaustive survey has been undertaken of all the erratics at present visible in the area selected, the one-inch map being divided into squares, and each square allotted to a worker, who will record every erratic above ground. The value of such a survey, in the elucidation of the complex problems of glacial geology, can hardly be over-estimated.

The Barnsley reports refer to a series of erratics, some of which were observed many years ago, but only a few of which were recorded. Fortunately, a local worker, Mr. W. Hemingway, preserved the information left in his hands by Professor A. H. Green, and supplemented it largely by his own observations. Mr. T. Tate, Secretary of the Yorkshire Boulder Committee, and the present writer, went over much of the ground under Mr. Hemingway's guidance, and can thus corroborate his testimony on many important points; though a very large proportion of the erratics, especially such as were of a hard nature, have disappeared under the hammer of the roadmender. (It would be well here to remark that a like fate is rapidly overtaking many of the most interesting and significant of the ice-borne boulders in the country, and to reiterate the oft-repeated appeal to local observers to take prompt measures to record and, if possible, to preserve -the erratics which come under their notice.) The especial interest of the groups observed lies in the fact that they are quite detached from the main lines of transport, and are so placed that they conceivably may have come by either of three routes-viz.: (1) with the train of erratics, exclusively from the Lake District, which is traceable down Calderdale to within a few miles of Royston and Barnsley; (2) with the dispersion of Brockram, Shap granite, and other Lake District rocks, with a few Scottish rocks, which can be traced down Teesdale and the Vale of York; or (3) with the coast dispersion characterised by a similar series to that of the Vale of York, with some Scandinavian and other crystalline rocks superadded. The abundance of rocks from the northern part of the Lake District is conclusive against (1), while the occurrence of crystalline rocks, red and grey granites, gneissose granites, and felspar porphyries, certainly coming from neither English nor South Scottish sources, seems equally against (2), leaving the third the probable direction of origin. Mr. Tate recognised a Norwegian aspect of the non-British rocks.

Another important report is that by Mr. W. Andrews, giving details of the dispersion of boulders from six small bosses of syenite which crop out about Sapcote, near Leicester.
