During a recent examination of some Coal Measure non-marine lamellibranchs in the collections of the British Museum (Natural History), my attention was drawn to a specimen from the Sowerby Collection labelled “Unio subconstrictus J. Sow., Coal Measures, Derbyshire”. On the back of the specimen were the remains of an original label, partly defaced, which some previous worker had endeavoured to read, for the words “Chapel … Sheffiel[d]” had been neatly copied on to another label affixed to the specimen.

Among the numerous fossils obtained by Dr. L. Moysey from the clay-ironstone nodules of the Coal-measures near Ilkesťon, Derbyshire, is one referred to by its discoverer as “a shrimp-like animal,” in a recent note published by him in the Geological Magazine for May last. Dr. Moysey was so fortunate as to secure several well-preserved examples of this very interesting Schizopod Crustacean from a disused brickfield on the Shipley Hall Estate, owned by E. M. Mundy, Esq. These he most liberally placed in my hands to examine and describe. Dr. Moysey also commended me to the Rev. C. Hinscliff, M.A., of Craig Royston, Bickley, Kent, who had in his possession another specimen of this crustacean obtained from the same locality. Mr. Hinscliff not only sent me his fossil to study, but generously presented it to the Geological Department of the British Museum (Natural History Branch), Cromwell Road, where it will be preserved and exhibited

Pygocephalus Cooperi was first described by Professor Huxley from the Coal-measures of Paisley in 1857 (Quart. Journ. Geol. Soe., vol. xiii, pp. 363–369, pi. xiii), and a second specimen by the same author in 1862 (op. cit., vol. xviii, pp. 420–422, text-figure). Some additional specimens came into my hands for exami-nation, and were communicated to the Glasgow Geological Society, in 1866 (Trans. Geol. Soc. Glasgow, vol. ii, pp. 234–247, pi. iii, figs. 1–3). In that paper I described a second species, which I named Pygocephalus Huxleyi (text-figure, p. 244, op. cit.). The specimens referred to above were obtained from the Coal-measures of Paisley, from Kilmaurs, and from near ilanchester. Since then the late Mr. Henry Johnson, F.G.S., formerly of Dudley, obtainedmany examples of Pi/gocephalus from the Clay-ironstone nodules of Coal-measure age at Coseley, near Dudley, now in the Geological Department of the British Museum (Natural History Branch), Cromwell Itond, S.VV. These specimens are preserved in great perfection, and I had fully intended to figure them some years ago, but the pressure of other work caused them to be set aside for a time. Last year I received an example of Pygocephalm from Mr. Walter Baldwin, P.G.S., obtained from the Clay-ironstone of the Middle Coal-measures at Sparth. Rochdale (for description see Fig. 1, p. 405). I have also received through Mr. H. A. Allen, F.G.S., of the Geological Survey Museum, Jermyn Street, by the kindness of their owner, Mr. Herbert Hughes, Assoc. E.S.M., F.G.S., of Horseley House, Volverhampton Street, Dudley, four most interesting specimens of Pygocepkalus collected by him, two of which prove to be females, a point of extreme interest not heretofore observed.

Having had our attention directed by Mr. Barkas's paper to the specimens of this genus in the National Collection, and compared Mr. Barkas's figures with Mr. T. Atthey's description of Ctenodus tuberculatus [see “Annals and Magazine of Natural History” (4th series), Feb. 1868 (p. 83)]; Mr. W. Davies having also kindly pointed out to us a small but very perfect palatal tooth (see Plate IX. Fig. 3), probably from the Coal-measures of Carluke (from the collection of the late Mr. Alexander Bryson of Edinburgh), closely agreeing with Mr. Atthey's description in all its characters; we have thought it well deserving of a place in our Plate.

SummaryHeyite occurs in silicified limestone with other oxidation-zone minerals derived from galena, chalcopyrite, and pyrite. The occurrence is near Ely, Nevada. Most common are pyromorphite, cerussite, and chrysocolla. Heyite occurs on and replaces corroded tungstenian wulfenite. Crystals are small (up to 0·4 mm), simple in habit, and monoclinic. Only {001}, {100}, {110}, and {01} have been observed. Twinning on {110} is relatively common. The colour is yellow-orange with a yellow streak, H = 4. Electron probe analyses (average of three) gave PbO 75·4 %, ZnO 0·81 %, FeO 8·41 %, V2O5 12·65 %. This leads to Pb5(Fe,Zn)2(VO4)2O4, with Z = 1.The space group is P21/m. Cell constants, refined from powder data, are a 8·910 Å, b 6·017, c 7·734 (all ±0·004 Å); β III° 53′±4′. The strongest powder lines (Cr-Kα) are: 3·248, 11, (100); 2·970, 30, 21 (69); 2·767, 211 (61); 4·873,110, (46); 3·674, 111, (35); 2·306 (33); 3·010, 020, (29); 3·412, 20, 11, (25); 8·281, 100, (25); and 2·113 (20). Gcalc 6·284, Gmeas 6·3±0·2 Optically biaxial with 2Vγ 82°calc, 89°meas; αD 2·185, βD 2·219, γD 2·266; all values ±0·01 and determined in S-Se melts. Dispersion is weak with π > ν. The orientation is β = b, α: [001] 36° (in obtuse β). Nonpleochroic.Three small specimens were found, and represent a total of less than 100 mg of the mineral. One has been deposited with the British Museum (Natural History). The name is for Dr. Max Hey, eminent British chemist and mineralogist.The cell is strikingly similar to that of brackebuschite but electron probe examination of a newly analysed (by atomic absorption) specimen of the latter from the type locality in Argentina shows a marked chemical difference. Heyite strongly resembles descloizite in appearance.

For some years past a Committee of Littleborough and Rochdale geologists, consisting of Messrs. W. H. Sutcliffe, Walter Baldwin, W. A. Parker, S. S. Platt, and others, have devoted themselves to the task of working out the beds of shale containing clay-ironstone nodules, a portion of the Middle Coal-measures at Sparth Bottoms, half a mile south-west of Rochdale Town Hall, in beds estimated to occur 135 feet above the Royley Mine Coal-seam.In the clay-ironstone nodules occur well-preserved ferns, Calamites, Sigillariœ, shells of Carbonicola acuta and other Coal-measure lamellibranchs, whilst the number of Arthropoda obtained is probably unsurpassed in any locality of this formation.The first Arthropod obtained from Sparth Bottoms was noticed by Mr. Walter Baldwin, F.G.S., under the name of Prestwichia, rotundata, Prestw., sp. (Trans. Manch. Geol. Soc., vol. xxvii, part 6, 1901, pp. 149–155, with a plate); the second in 1903, by the same geologist, who identified it as Bellinurus bellulus, König (op. cit., vol. xxviii, part 8, pp. 198–202). The third and most important discovery was made by Mr. W. A. Parker, F.G.S., namely, a new species of fossil Scorpion, which was described and figured in 1904 by Messrs. Baldwin & Sutcliffe under the name of Eoscorpius Sparthensis (Quart. Journ. Geol. Soc., vol. lx, p. 396, fig. 2). These geologists have continued their researches, of which a brief account was given by me at the York Meeting of the British Association (1906). Many subsequent finds have been most obligingly confided to me by these gentlemen, and through the kindness of Mr. W. H. Sutcliffe the specimens figured have since been presented to the Geological Department of the British Museum (Natural History), the only condition imposed being that they should be described.
