In a collection of Coal-measure Vertebrata made by Mr. J. Ward, of Longton, and recently acquired by the British Museum, there is an imperfect, crushed skeleton of a small Labyrinthodont from the Ash-coal Shale of Longton Hall Colliery, Staffordshire. This specimen was noticed by Miall in 1874 in his British Association Report on the Classification of the Labyrinthodonts, where it is referred to Urocordylus, some of the characters given in his diagnosis of that genus being taken from it. Some measurements of the skull were added. The same specimen was afterwards figured in Mr. Ward's paper “On the Geological Features of the North Staffordshire Coal-field” (Trans. N. Staffs. Instit. Mining Engineers, vol. x. 1890, pl. ix. fig. 2) as Keraterpetum Galvani. This figure, which is natural size, unfortunately does not show any details of the structure of the skull, some account of which may be of interest.
