Several specimens of extinct species of the angel-fish or monk-fish (Squatina) are already known from the Lithographic Stone (Lower Kimmeridgian) of Bavaria, Würtemberg, and France; and some of these are in an admirable state of preservation. Two forms are clearly distinguishable—the one a small fish not more than 0·15 m.inlength, with a dense armour of rounded dermal tubercles on the anterior border of the head and each of the paired fins, and upon the lateral aspect of the tail; the other a comparatively large fish, attaining a length of at least a metre, without any similar development of the dermal tubercles, either in the regions mentioned or on any other part of the body.

Professor Charles S. Prosser Geological Department, JL Union College, Schenectady, N.Y., having sent me some specimens of Estheria found in the Red Beds or Cimorron Series of Kansas, with the request that I would determine the species, my notes on them are here offered to the GeologicalMagazine, in which other fossil Estheriæ from North America have been illustrated and described.

The name “Dene Holes” has been locally given to certain ancient artificial caverns usually found excavated in the Chalk of Essex and Kent. They have deep vertical entrances by shafts, being of varying depth, but the caverns themselves all bear a general similitude in design. They have been chiefly explored in the counties of Essex and Kent, although they undoubtedly exist in many other counties.

Having, in March last, received from Mr. Jukes-Browne, F.G.S., of the Geological Survey, a small carapace of a crab obtained by Mr. J. Scanes, of The School House, Maiden Bradley, from a quarry in the Chert Beds of Baycliffe, near Maiden Bradley, Wilts, I endeavoured to identify it with some species of Cretaceous Necrocarcinus already described, but without success. I am therefore reluctantly compelled to refer it to a new species. The specimen is rather imperfect, which renders the task of determining its characters the more unsatisfactory.

The section in which these rocks are exposed is seen in a field at a distance of about a quarter of a mile from the village of Martley and due north of Berrow Hill Farm. Here is a small excavation for road stone, but it does not appear to have been worked lately. Both the quartzite and syenitic rock are exposed, the latter being very decomposed. The relations of the rocks to one another appear to be as follows (see Figure):—Below, at A, the quartzite is seen to stand out conspicuously. Round this, as at B, is a thin layer of powdery rotten rock, differing but little from the rest of the decomposed syenite, forming a crust at C, but evidently marking the junction of the quartzite and syenite; the latter being at D and E sufficiently undecomposed to allow of its being sliced. Above comes a loose breccia consisting of fragments of these rocks, but this is evidently surface soil.
