NECROLOGY OF MINERALOGISTS: 1885.

E. E. SCHMID.-Born May 22, 1815, at Hildburghausen; died at Jena February, 1885; for many years professor at Jena. His work was largely in geology, but he made many contributions to mineralogy, chiefly of a chemical nature. BENJAMIN SILLIMAN.-Born December 4, 1816; died January 14, 1885; professor of chemistry in Yale College, New Haven, Conn. He was an editor of the Americau Journal of Science for nearly fifty years; author of works on chemistry and physics and of many papers upon American minerals, especially the minerals of the Western States and Territories

RECORD OF NORTH AMERICAN INVERTEBRATE PALÆON

TOLOGY.

By JOHN BELKNap Marcou.

INTRODUCTORY NOTE.

The same general plan has been followed as last year, although the scope of the work has been somewhat enlarged so as to include also reviews and bibliographic notices of palæontologic works; mere mentions of works by title have not been referred to. I have experienced some difficulty in getting hold of all the recent publications in time for insertion in this record, and there are doubtless some omissions. I shall be much obliged if those who notice them will call my attention to them so that they may be inserted next year. I wish to thank all those who have kindly aided me in collecting this material, and especially Mr. H. M. Ami, of the Canadian Survey, and Mr. C. E. Beecher, of the New York State Museum at Albany.

Cincinnati. Describes and illustrates a number of new species from the Eocene; mostly from the Red Bluff formation of the Vicksburg group.

These illustrated notes on Eocene shells are given with the hope of correcting some errors, shedding light upon obscure forms and recording the European species mentioned. The author intends to continue them with notes on synonomy,

The results of a personal examination of the Tertiary of Alabama are given so far as is necessary to reply to Dr. Meyer's papers; his quotations and views are also criticised and corrected. (See Meyer, Otto.)

Science's report of the proceedings of the meeting of the A. A. A. S. at Ann Arbor.

Three discoveries of fossils were announced. Prof. N. H. Winchell brought from the pipe-stone quarry of Minnesota a contorted trilobite of the Paradoxides type and slabs of sandstone covered with round phos phatic brachiopods referred provisionally to Lingula. Prof. W. B. Dwight reported the discovery of a unique Potsdam locality one mile northwest of Vassar College and in the Wappinger limestone belt. Prof. J. D. Dana exhibited Silurian fossils taken at Canaan, N. Y., from the sparry limestone of Emmons, a member of his original Taconic system as first defined by him in 1842. Prof. James Hall said that the existence of Silurian fossils in these rocks was claimed and admitted forty years ago, and Prof. N. H. Winchell argued that Emmons's later use of the title "Taconic," in which he applied it to certain rocks in New York, now known to be pre-Silurian, entitled the name to a place in stratigraphic nomenclature.

BAIN, FRANCIS, and DAWSON, J. W. (Sir).-Notes on the Geology and Fossil Flora of Prince Edward Island. Canadian Rec. Sci., vol. I (1884-'85), pp. 154-161, figs. 1 and 2, on pp. 160 and 161. 1885. Montreal.

Communicated to the Royal Society of Canada at its meeting in Ottawa, May, 1885. Sir William Dawson describes the new species Walchia imbricatula from the Trias; Sir William concludes that Mr. Bain's lower series is distinctly permo-Carboniferous; that its extent is considerably greater than was supposed in 1871; that there is a well characterized overlying Trias, and that the intermediate series, whether Permian or Lower Triassic, is of somewhat difficult local definition; but that its fossils, so far as they go, lean to the Permian side.

A large number of additions, hitherto not recorded, are mentioned from the Cambro-Silurian rocks about Ottawa.

BRITTON, N. L.-Cretaceous Plants from Staten Island. Trans. N. Y. Acad. Sci., vol. v, 1885-'86, pp. 28-29. November, 1885. New York. Notes the discovery by Messrs. H. Hollick, W. T. Davis, and himself of fossil leaves in the Cretaceous clays at Kreischerville, Staten Island. The specimens were obtained from a stratum of lignitic clay about 18 inches in thickness, and included angiosperms and conifers.

BRITTON, N. L., and HOLLICK, ARTHUR.-Leaf-bearing Sandstones on Staten Island, New York. Trans. N. Y. Acad. Sci., vol. III, 1883–'84, pp. 30, 31. 1885. New York.

Dr. Britton considers the sandstones of Cretaceous age, although the fossils are insufficient for proper determination. Similar fossiliferous sandstones occur on the beaches about Glen Cove, Long Island, and vicinity.

American as well as European forms are discussed in this review of Palæozoic insects. Some new forms are named, but they are all from Commentry.
