During the last two years four papers have appeared upon the Australian Cainozoic Echinoids, contributed by M. Cotteau, Prof. R. Tate, Herr A. Bittner, and myself. These add considerably to our knowledge of the fauna; they show that it is Eocene and Oligocene, instead of Miocene, and that it is remarkably varied and rich in genera. I am now able to add one or two more species to the list, and at the same time take the opportunity of referring to one or two changes proposed by Prof. Tate and Herr Bittner.

During my visits to West Bay, Bridport, in the years 1887 and 1888, I was able to examine the following inland sections of the Lias Junction Bed, and I communicated a paper to the British Association at Leeds in 1890; an abstract of this paper appeared in the Report. I had hoped to obtain more evidence of the nature of this deposit, but, unfortunately, last year, 1891, I found that the working of the Allington brickfield was being abandoned, and that it was difficult to further work the roadside cuttings without doing considerable damage. I therefore think it better to lay before the readers of the Geological Magazine my notes on this deposit, which I shall be able to show is variable in different sections, due to the amount of denudation which has taken place.

I Quite agree with Mr. Goodchild's statement in the July Number of the Geol. Mag. that the stratigraphy of some of the areas in which the Coniston Limestone Series is developed “presents very considerable difficulties,” so much so that in the areas of Cross Fell and Settle portions of the “country might be described as consisting of a gigantic fault-breccia,” and that it is necessary “to go over a large part of this faulted area again and again” in order to interpret its structure. I do not know whether Mr. Goodchild would class me amongst the “less fortunate” ones who have not been over the ground again and again; possibly I have not devoted the amount of time which he has been able to give to the study of the rocks of the Cross Fell Inlier, but it must be remembered that Prof. Nicholson, with whom I had the pleasure of working at this inlier, has returned to the ground again and again during a long course of years, whilst more recently, he and I have devoted several vacations to its study, and we have carefully compared the beds and their fossils with those of adjoining and more distant areas.

In a review of Nicholson's “Geology of Cumberland and Westmoreland,” which appeared in the GEOLOGICAL MAGAZINE about a quarter of a century ago, the reviewer observes, in referring to some remarks upon the Shap Granite, that this and other granites have clearly taken the place of the rocks whose position they occupy, and that, in fact, intrusive rocks can be shown, in a great majority of instances, to have replaced, rather than to have displaced, the rock masses which they invade. The reviewer's identity with a wellknown Professor of Geology at one of the English Universities is sufficiently evidenced by his intimate acquaintance with the geology of British Silurian and Cambrian rocks.
