  • In Denbighshire the Marl follows the productive Middle Coal Measures and consists of from 400–1,100 feet of red, green, and variegated marls with occasional sandstones and towards the top thin Spirorbis limestone and other limestones, with here and there films of coal. It corresponds with the Etruria Marl of the North Staffordshire Coalfield.

  • Notes on a collection of Dentalium neohexagonum S. and P.

  • D. K. Greger
  • Published online by Cambridge University Press:
    01 May 2009, pp. 236-237

  • Through the kindness of a correspondent in Southern California, the writer recently acquired a series of 320 superb examples of Dentalium neohexagonum S. and P. collected from the Fernando formation of that state. The following somewhat detailed account of the variations occurring in the collection may prove of interest to students of the Scaphopoda. Our study of this series is supplemented by the addition of other material of the species, collected by Charles Sternberg, from the Pleistocene in the vicinity of San Quintin, Baja California, Mexico, and a few examples of the species, now found living off the California coast, dredged by Henry Hemphill.

Original Articles

  • A Triassic Crinoid from Brazil

  • F. A. Bather
  • Published online by Cambridge University Press:
    01 May 2009, pp. 237-238

  • In “Faunas Triassicas do Brasil”, by F. R. Cowper Reed (Monogr. Serv. Geol. Brasil, ix, 1929), there occurs on pp. 84, 85, a note by me on an obscure crinoid. This should have been accompanied by an illustration, but the drawing supplied was not reproduced. It has recently been returned to me by Dr. Cowper Reed, who concurs in my suggestion that it should now be published since the occurrence is certainly interesting and is liable to be overlooked among the wealth of lamellibranchs described by him, and beautifully figured on his plates by E. T. Talbot.
