PALEONTOLOGY. 303 



E. D. Cope (51) states that he has found evidence of the presence of 

 the pineal eye in some ancient vertebrates, and calls attention to the 

 bearing of this fact n[)on the relationship of the vertebrates with the 

 tunicates. In the phites published with this paper illustrations are 

 given of Botknolcpis Canadensis, the skull of Miictcrops ordinatns, Dia- 

 (Icctes phascolinus, iiud the cranium or brain cases of Belodon buceros, 

 and Allu/ator Mississippiensis. The announcement of this discovery in 

 early rei)tilian vertebrates evidently su,i:jgcsted the following; pa})ers : 

 H. F. Osborne (205, 2()G) upon reading Owen's descri[)tion of Tritylodon 

 of the Upper Triassic of South Africa, in which the author refers to a 

 vacuity between the parietals which "if natural, represents a fontanelle, 

 or it may be interpreted as a pineal or parietal foramen; it may how- 

 ever be due to posthumous injury," infers from this the remarkable hy- 

 l)()thesis that "the primitive mammal of the family to which this be- 

 longs had a pineal eye of some functional value." But examination of 

 the specimen itself by Dr. George Baur brought out the fact that no 

 parietal foramen exists in TriUjlodon (L'OS). Thus suddenly the pineal 

 eye of the primitive mammal is knocked out. 



Mr. Cope (46) gives some new facts regarding the shoulder girdle 

 and extremities of Eriops, and (44) presents a number of tables ex- 

 pressing the supposed phylogenetic relations of the several genera of 

 artiodactyla, tracing them through the various stages of the Tertiary. 

 The next (54) is apparently a modified form of this same paper. In 

 another paper (42) the author describes a part of the mandible of a 

 large cat from the Upi)er Miocene beds of Phillips County, Kansas, 

 wliich is named Machwrodus, and specific name catocopis. No figures 

 are given. 



Mr. Osborne (200) finds the name Afhrodon, proposed in the paper 

 (203) above referred to, preoccupied by Sauvage, and he proposes Kur- 

 todon as a substitute. 



A memorandum (80) of a paper read at the meeting of the Academy 

 of Science in Paris, July 30, 1888, by M. Albert Gaudry, is given in a note, 

 Nature, vol. xxxviii, p. 384, in which the author records the relative 

 dimensions of some of the larger Tertiary and Quaternary matnmals; 

 Dinothcrium (jirjanteum is given the first place, and Mastodon Anieri- 

 canus of the Quaternary of the United States is given the fourth place. 



Mr. Cope (48) announces the discovery of a fragment of the carapace 

 of Glyptodon in Nueces ('ounty, southern Texas, in beds which have 

 yielded Equus crenidens, Cope. The discovery was made by William 

 Taylor, and tlie si)ecimen is described and nanuid Glyptodon petaUfer- 

 ous (s}). nov.), J)]*. 345, 340. 



J. A. Allen (2) describes from the Miocene of Charleston, South Car- 

 olina, HquaJodon Tledcmanni (sp. nov.), j). 35, jds. v, vi. 



J. M. Clarke (20, 30) annouiuies the discovery of elephant bones as- 

 so(uat('d with charcoal and pottery at Attica, Wyoming County, New 

 York.
