Fig. 13. "The mandible and tooth of a recent fish (_Diodon_), to compare with the fossils figs. 16, and 17."--_Mr. Parkinson._ Fig. 14. "Fossil palate of a fish, from Sheppey."--_Mr. Parkinson._ This evidently belonged to a species of _Ray_; possibly to the Eagle rays (_Miliobatis_). Fig. 15. Tooth of a fish allied to the _Cestracionts_, or Port Jackson Shark, (probably of the genus _Acrodus_,[70]) from Bath; commonly called "_Leech palates_" by the quarry-men. [Footnote 70: Medals of Creation, p. 614.] Figs. 16, & 17. "Fossil palates of fishes of the Ray kind, from Sheppey."--_Mr. Parkinson._ These appear to belong to the Miliobates (_M. micropleuris_, of Agassiz). Beautiful examples of these fossils have been obtained from the Bracklesham clay, on the coast of the West of Sussex. The late Frederic Dixon, Esq. of Worthing, whose untimely death is so much to be deplored, had a matchless suite of specimens from that locality. Fig. 18. A fine specimen of a fossil tooth of a fish of an extinct genus, of which many species occur in the chalk (_Ptychodus polygurus_, of Agassiz). The teeth of various species of this genus of Sharks abound in the chalk of almost every part of England.[71] [Footnote 71: Ibid. p. 616; and plate vi. fig. 2.] [Illustration: Plate LXXI.] PLATE LXXI. Fossil Remains of Mammalia. Fig. 1. "a fossil tooth, probably of some animal of the whale kind."--_Mr. Parkinson._ I am not able to determine the nature of this specimen. Fig. 2. The antlers and skull of the Fossil Elk, of Ireland, (_Megaceros Hibernicus_.) The original was nearly eleven feet across, from the point of one antler to another. A perfect skeleton of this extinct gigantic deer is exhibited in the Gallery of Organic Remains in the British Museum. For an account of this animal see Wonders of Geology, vol. i. p. 132; and _Supplementary Notes_, p. 189. The following measurements of the specimen figured are given by Mr. Parkinson; Feet. Inches. _a_ to _b_ 10 10 _c_ to _d_ 5 2 _e_ to _f_ 3 7½ _g_ to _h_ 2 6 _i_ to _k_ 1 10½ _d_ to _l_ 1 2 Diameter of the horn at _m_ 0 2¼ Circumference, " 0 8 " at the root 2 11 Length of the cranium from _n_ to _o_ 2 0 Width " " _p_ to _q_ 1 0 "A similar pair, found ten feet under ground in the county of Clare, was presented to Charles the Second, and placed in the guard-room of Hampton Court Palace."
