the writer has obtained from the lowest part of the Malvern Black 

 Shales a species identical with the Stockingford form, which had 

 been provisionally identified with the Swedish Beyrichia Angelini. 

 The characters of these specimens serve to separate the species from 

 those now placed under the genus Beyrichia, a conclusion in which 

 Professor T. Rupert Jones concurs. The specimens were obtained 

 from Black Shales at the northern extremity of Chase End Hill, 

 associated with Acrotreta, Agnostus, Kutorgina pusilla, and Prolo- 

 spongia fenesirata. The shales are nowhere actually exposed, and 

 can only be reached by excavation. The specimens are frequently 

 crushed and iudented. The new genus appears to be most nearly 

 related to those provided with broad lobes, such as Kloedenia, 

 Beyrichia, Ctenoholina, and Tetradella. Specimens obtained by 

 Professor Lapworth from the Oldbury Shales below the zone of 

 Sphcsrophthalmus alatus are also referred to the same genus and 

 species. From Linnarsson's description of Beyrichia Angelini it 

 would seem that this form may be related to the new genus, but 

 it clearly belongs to a different species. 



2. "The Sequence of the Cambrian and Associated Beds of the 

 Malvern Hills." By Professor Theodore Thomas Groom, M.A., 

 D.Sc, F.G.S. With an Appendix on the Brachiopoda by Charles 

 Alfred Matley, Esq., B.Sc, F.G.S. 



The series, exclusive of some 600 feet of igneous rocks, may be 

 estimated at between 2,500 and 3,000 feet, and consists of the 

 following members, tabulated in descending order : — 



4. The Bronsil Shales, 1,000 feet thick ; grey shales containing Bictyonema and many 



Treraadoc brachiopods and trilobites. 

 3. The White-leaved Oak Shales ; black shales, including : 



ih) The zone of Feltura scarahceoides, Sphcerophthahmis alatus, Qtmopyge 



pecten, Ct. hisiilcata, Agnostus trisectus ; 500 feet. 

 [a) The zone containing Kutorgina pusilla, Protospongia fenestrata, a new 

 variety of Acrotreta, and a new genus of the Leperditiadee ; 30 feet. 

 2. The HoUybush Sandstone, comprising : 



(J) Massive Sandstone, probably not less than 1,000 feet thick, and containing 

 Kutorgina Fhillipsi, Orthotheca fistula, Scolecoderma antiquissima, and 

 new species of Hyolitlius. 

 [a] Flaggy and Shaly Beds, not less than 75 feet thick ; chiefly flaggy and 

 shaly glauconitic sandstones, with Kutorgina Fhillipsi, Scolecoderma 

 antiquissima, Hyolithus, etc. 

 1. The Malvern Q,uartzite,i consisting chiefly of grey quartzites and conglomerates, 

 rarely glauconitic ; probably at least several hundred feet thick ; containing 

 Kutorgina Fhillipsi, Hyolithus primcevus, and a new species of Obolella. 



The last rock, though now separated by faults from the older 

 Malvern Series, contains angular fragments both of Uriconian and 

 Malvernian type. It is correlated with the Wrekin Quartzite and 

 with the lower divisions of the Hartshill Quartzite. The Flaggy 

 and Shaly Beds appear to correspond with the Olenellus-he^s and 

 the zone of Paradoxides Groomi in Shropshire. The bulk of the 

 Hollybush Sandstone probably represents the greater part of 

 the Paradoxidian of other localities, and may in part correspond 

 with the Purley Beds of Nuneaton.
