The most common forms from the Lower Coal-measures of Hortonbelong to the very wide-spread and abundant species, LeperditiaOlteni (Miinster). Some of our specimens received from this localitywere separately mounted on cardboard; others occur plentifully inhand-specimens of hardish grey shale, where they are associatedwith species of Beyrichia and Cythere (?), hereafter noticed.

They are small, being only about -2-0- inch,or 1-4: millimetre long, and 1 mm. in height, of which size theyoccur in European strata, though they are as often found larger, evenup to double the length. This species has been described and figured by us from Bavarianspecimens (supplied to us by Dr. Giimbel) and Russian material(from the late Dr. von Eichwald), in the Annals and Magazine ofNatural History, ser. 3, vol. xv. 1865, p. 406. 2.—Lepekditia Okeni (Miinster), var.
