pages. — The paper contains valuable notes on several of the 

 species of these beds. The facts with regard to the Creodont, 

 Pakeonictis occidentalis are illustrated by a large plate showing 

 the jaws and teeth ; and figures ot the dentition of Pacbyama and 

 other genera are contained in the text. Coryphodon is described 

 as being plantigrade behind while digitigrade in the forefeet, and 

 figures are given. The skull of Systemodon tapirinus is repre- 

 sented. These are a few of the many points brought out. 



Revision of the Species of Coryphodon, by Charles Earle. 

 For the preparation of this paper Mr. Earle had access to the 

 collections of the American Museum of Natural History, and the 

 collection of Coryphodon remains of Prof. Cope which was libe- 

 rally placed at the author's disposal. The number of species 

 which had previously been described is twenty-one, seven of 

 these under the genus Coryphodon, ten under Bathmodon, two 

 pertaining to Metalophodon, and one to each Manteodon and 

 Ectacoclon. All were described by Cope except one species of 

 Coryphodon, C. hamatus of Marsh. The study of the specimens 

 by Mr. Earle has led him to reduce the number of species to ten ; 

 Coryphodon radians, C. testis, C. elephantopus, C. cuspidatus, 

 C. hamatus, C. obliquus, C. curvicristis, C. anax, Manteodon 

 subquadratus and Ectacodon cinctus. He expresses doubt with 

 regard to C. hamatus, as he had not seen the specimen. 



Characters of Protoceras (Marsh), the neui Artiodactyl from, 

 the Lower Miocene, by H. F. Osborn and J. L. Wortmax. — The 

 specimens of this horned Artiodactyl belong to the species P. 

 celer of Marsh. The collections of Prof. Marsh include a 

 female skull, and those of the American Museum a male. Both 

 are here described and figured, and also the bones of the fore and 

 hind feet. The Protoceras celer was made the type of a new 

 family by Marsh ; and this view is sustained by the authors. 

 They place the family between the Tragulina and the Pccora. 

 From the latter they are widely different, having no marked 

 affinities in the direction of either of the families, the Giraffidae, 

 Cervhilae or Bovidae. From the former the divergence is less 

 great, but instead of having no horns, they have multiple horns, 

 there being paired bony protuberances on the parietals, frontals 

 and maxillaries, besides having several other important points of 

 difference. The number of these bony protuberances on the 

 cranium is ten. These protuberances however are not horn-cores, 

 but had a dermal covering. '•' The grotesque appearance is 

 heightened by the large canines, which give the lateral aspect of 

 the skull a decided suggestion of resemblance to that of the 

 Uintatherium." 



The Proceedings of the Academy of Natural Sciences of Phila- 

 delphia for August, 1892, contains (pp. 291-323) a "Revision of 

 the Nortli American Creodonta " by W. B. Scott, with notes on 

 some genera which have been referred to that group, based 

 chiefly on the large collection of Professor Cope. The following 

 provisional families are described : Oxyclsenidae, Arctocyonidae,
