There is, however, a general resemblance between the two animals ; and the fully grown Cervus verticornis must have rivalled the Irish Elk in size, although its antlers were not so wide in their sweep, or so elegant in their outlines.

The following are the measurements (in inches) of the principal antlers which I have examined:—

2. Other Species from the Forest-bed.

The Cervidæ of the Forest-bed present a most remarkable mixture of forms. Dr. Falconer has determined one species, Cervus Polignacus (Palæontographical Memoirs, ii. p. 479), which occurs also in the Pliocene lacustrine deposit of Mont Perrier, near Issoire; and he has described a new species, with peculiar flattened branching antlers, as 'C. Sedgwickii (op. cit. p. 476). The Stag, Roe, and Cervus megaceros' are also present. To these I am now able to add the species which M. Laugel obtained from the Pliocenes of St.-Prest, near Chartres, and described in the 'Bull, de la Société Géol.' 2d ser, xix. p. 711, 1862, under the name of Cervus (megaceros) carnutorum.

It is based on the frontlet with portions of the beams of the antlers. The latter are round and deeply grooved, and the burr is strongly defined and annular. The brow-antler is removed nearly 2 inches from the burr, and rises at an acute angle to the beam. According to Prof. Gervais, the skull differs from that of the Irish Elk in the interval between the bases of the antlers being smaller. The following measurements are taken from his work 'Animaux Vertébrés vivants et fossiles,' 1867–9, p. 85:—
