These notes on fossil Phyllopods refer to some interesting specimens, mostly of Palæozoic age, which have come to hand since the publication of Part II. of our “Monograph of the British Palæozoic Phyllopoda” (Palæontographical Society), 1892.

The genus Elotherium, established by Pomelin1847, represents a family of extinct mammals, all of much interest. They were first foundinEurope, but now are known in the Miocene of North America, not only on the Atlantic coast, but especially in the Rocky Mountain region, and still further west. This family includes several genera, or subgenera, and quite a number of species, some of which contain individuals of large size, only surpassed in bulk among their contemporaries by members of the Rhinoceros family, and of the huge Brontotherid

The specimens which form the subject of this paper were obtained by Mr. E. J. Garwood from the Carboniferous Limestone of Stebden Hill, near Cracoe, Yorkshire; and the writers are indebted to the kindness of Mr. Garwood for permission to describe them. Respecting the horizon and locality from which the species came, Mr. Garwood says, in a letter to one of the writers: “Stebden is a hill which Tiddeman [of the Geological Survey] describes as one of his knoll reefs

Italian geologists have made several valuable contributions to our knowledge of the Jurassio strata of their country. Unfortunately some of their works are not known here as they deserve to be, and seem difficult to obtain. At the same time I have to acknowledge with thanks the receipt of some valuable memoirs which have been of particular service; and one of the latest arrivals is the present pamphlet.

Dr. H. C. Mill has recently made elaborate bathometric surveys of the principal English lakes, and whilst taking the soundings he has collected a series of samples of the bottom-deposits, for the purpose of microscopic study.

At the request of Mr. Marr I undertook a careful mineralogical examination of these samples, and, though nothing very striking or specially interesting has resulted from the work, it may be worth while to record in the Geological Magazine the fact of such an examination having been made, and to state the mineralogical and other observations noted.

In a previous paper on the Loess of S. Kussia, I endeavoured to discuss its character and origin, and to compare the facts observed with the results obtained by many students of the latest phases of our earth's history.inso doing I overlooked two articles on this subject, which appeared in the GEOLOGICAL MAGAZINE for 1882, and embodied the views held by Baron von Eichthofen and Sir H. Howorth respectively.

After I had written the above dissertation and sent it for publication my attention was kindly drawn to a paper, dealing with the same subject, communicated by Mr. T. Mellard Reade, C.E., F.G.S., to the Liverpool Physical Society, and since republished in the May number of the GEOL. MAG. for this year (p. 203).

General Mcmahon's paper in the GEOLOGICAL MAGAZINE for June attacks my conclusion that the Malvern biotite is formed from chlorite, but leaves my evidence untouched. Indeed, a large part of the article is occupied in discussing a theory which I do not hold. I have never said that the chlorite was converted into biotite by contact-action only. That there may be no further mistake, let me repeat that, in the Malvern rocks, chlorite is changed to biotite by contact-action plus dynamic deformation.
