Holland, or Whitewell, Yorkshire; William Gilbertson collection, purchased 1841. Athlone by Robert Young (1821-1917), a railway engineer, and presented to the Belfast Natural History and Philosophical Society. In K5119 a third of an outer whorl is preserved in matrix (diameter of shell 18-20 cm, plus spines 30 cm), and in Kl 665 there is half of a whorl with a diameter of 17 cm, but no spines. In thin sections from the matrix of K5119 John Wilson of the Ulster Museum has recently found large specimens of the foraminifer Ammarchaediscus (Rectodiscus) sp. These are normally indicative of a late Arundian age. The specimen listed by Carrington (1865 : 49) from Wetton, Derbyshire as Phanerotinus cristatus is now in the Sheffield City Museum; upon examination it proved to be a fragment of the brachiopod Pugnax. Stubblefield in Mitchell & Stubblefield (1941) identified possible examples of Phanerotinus cristalus in a fauna from the Productus humerosus Beds (=€3) at Breedon-on-the-Hill, Leicestershire, but although this material should be in the IGS collections we have been unable to examine the specimens. Occurrence and locality. J. de C. Sowerby recorded that the figured specimen (G184) was from 'Whittle' in Yorkshire, while Phillips had earlier given the locality as Bolland. It is now realized that Phillips used the locality Bolland in a much more restricted sense than Gilbertson. In the spring of 1835, Phillips had carried out an extensive geological survey of that district, whereas Gilbertson simply used the name for the broader district in which he.
