Extract

My friend Professor Lapworth kindly sent me, for identification, in July last the split portions of two nodules containing examples of the interesting little Crustacean genus Cyclus, from the ‘Pennystone’ Ironstone of the Coal-measures near Dudley, obtained by Miss Ethel M. R. Wood, M.Sc., of the University of Birmingham, and I have obtained permission to publish a note thereon, supplementary to my paper in 1894. In that paper I described, among other species, one which I named Cyclus Johnsoni (op. cit., Pl. XV, Figs. 4–7, pp. 537–538), from the Coal-measures, Coseley, near Dudley, which is identical with Miss Wood's specimens. As one of these latter displays some further details of appendages I have given a figure of it here as tending better to elucidate the structure of this curious genus. (See Woodcut on p. 491.)
