Abstract
The following descriptions of Shropshire trilobites, mostly collected from urchison’s (1839) type section of the Caradoc Series, are from Bancroft manu-sripts which will ultimately be deposited in the British Museum (Natural History), here the Bancroft Collection of fossils is housed. As far as possible the original xt has been preserved, apart from material necessary to bring it up to date and tsertion of references to various publications. Since in Bancroft’s paper on ryptolithinae (1929) the illustrations were reproduced from drawings, it has been bought well, as suggested by Richter (1930, pp. 556 - 557), to refigure some of the species from photographs. A few of Bancroft’s unpublished trilobites have been ealt with by Reed (1932) and Shirley (1936). In these cases only a minimum of reference is now given, but Bancroft’s illustrations have been retained. A recent paper by Harper (1947) describes some related species from the Lower Longvillian if Caernarvonshire. It may be added that Dr C. J. Stubblefield has given help with the text of the present publication. He, Mr R. Baker and Mr W. H. C. Ramsbottom searched for the type specimens in the Natural History Museum. Thanks to their co-operation, most of the figured examples have now been identified with the photographs.
