PALAEOMERYX. 



This genus is represented in my collection by portions' of two 

 mandibles, and, probably, by the superior dentition posterior to the 

 second premolar. One ramus contains the six molars and premolars 

 complete, and is in every essential character like the Eiu'opean Fale- 

 omeryx including tiie characteristic Paleomeryx fold. The other 

 larger species is represented by a portion of the ramus containing the 

 three molars, somewhat broken, but all showing this fold more plainly 

 than in the preceding from which in it has nearly disappeared— espec- 

 ially on molar 1 — on account of the teeth being much worn. 



There is now little doubt that the name Palaeomeryx as now used 

 applies to American as well as Old World species; but this is 

 no cause for surprise as its discovery has been expected. Though 

 these jaw fragments belong to the genus called Palaeomeryx 

 yet it does not settle all the points of doubt respecting this 

 genus. A series of upper teeth in my possession correspond in 

 size with the portion of mandible of the smaller species; and though 

 they were not found together, I have little doubt that they belong to 

 the same species. These upper teeth are veiy much like those of 

 Elastomer yx antUopimis ' Scott, so I think that, as Scott mistrusted, 

 Blastomeryx is really Palaeomeryx, if as Schlosser suspected the type 

 of the latter possessed horns, or, if the possession of horns is not 

 of generic value. 



Note.— Since writing the above I have found a skull, which, though 

 slill in the matrix, is evidently almost like Cope's ^/ff^/w/wez-^.THnd is 

 about the same size. With it is a mandibular ramus and other bones. 

 I partly cleared the matrix from the mandible and find that it differs 

 little from the two mandibles here described except that it is larger 

 than either. This much is certain that the skull of the so called Blas- 

 tomeryx has been found associated with a mandibular ramus that 

 differs in no important particular from the European Palaeomeryx.
