V.—Note on the Generic Identity of the Genus Esthonyx, Cope, with Platychœrops, Charlesworth (=Miolophus, Owen)
Published online by Cambridge University Press: 01 May 2009
Extract
In an early number of the present serial Prof. Sir R. Owen described and figured the hinder part of the palate of a small mammal from the London Clay of Herne Bay, under the new name of Miolophus planiceps. The specimen is now preserved in the Museum at York, and had been previously described by Mr. E. Charlesworth under the name of Platychœrops Richardsoni; a circumstance which seems to have escaped the notice of Sir R. Owen. This name having the priority should supersede that of Miolophus. The specimen (of which there is a cast in the British Museum) shows the second and third true molars of both sides, and on the right side the fourth premolar and the alveoli of pm 3 and m. 1. Both the later premolars and true molars are of the same general form, and have tritubercular crowns. Sir R. Owen regarded the specimen as indicating a form allied to Hyracotherium (including Pliolophus); but the similarity between the premolars and true molars and the trituberculate crowns of the latter forbids the acceptance of this view

The writer finds it will be necessary to issue a supplement to this part, as he is continually coming across specimens in the Museum which have hitherto been referred to other orders, but which he now finds should be included in those treated of in this part. He proposes (with the sanction of the Museum authorities) to issue this supplement on the completion of the Catalogue of the Ungulata.Google Scholar
