1896.] Geology and Paleontology. 481 



In " La Petite Galerie " of Paleontology at the Jardin des Plantes, 

 Paris, there is a well preserved skeleton of Paloplotherium which is la- 

 belled P<iloplotli>rium min u*. This specimen is of some importance, as 

 we have here a case where the skeletal parts and teeth are associated 

 and from the same individual. This skeleton was found in the Caleaire 

 Grossier de Dampleix, Department of Aisne,* and it is important to add 

 that Professor Gaudry's type of P. codiciense is from the same horizon 

 of this Department, but from another locality. 



Although this skeleton has been determined as P. minus it differs 

 widely from this species, and also in fact from P. codiciense. In the 

 upper and lower jaw there are four premolars as in P. codich nsr, but 

 these teeth are much more complicated than in that species and are 

 exactly transitional in structure between P. codiciense and the typical 

 species of Palceotherium. The premolars in this type are badly worn, 

 but I can distinctly trace on one side that the internal cones are nearly 

 double, but not distinctly separated as in Palceotherium ; the structure 

 the true molars is like that of P. codiciense. As will be seen the den- 

 tition of the skeleton above referred to differs from Pbloplotfu Hum 

 minus in having four premolars, also the second upper tooth of this 



The parts of the skeleton associated with the teeth and skull conewt 

 of a scapula, radius and ulna, and also some metapodials. Among the 

 latter there is a Mc. Ill and also another metacarpal, which I think 

 may be Mc. V. If this determination be correct, we have here a 

 Pakeotheroid with four digits to the mamus. In the species of Palceo- 

 rium from the Upper Eocene, Mc. V is represented only by a i 1 1 ent. 

 I would like to add that the metapodial in this skeleton which I have 

 determined as Mc. Ill is flatter and less triangular in section than in 

 the typical Puh.p/othrrium minus; this goes to show that the lateral 

 toes were larger, and supports my view as to the presence of four ante- 

 rior digits in this as yet undescribed species. 



From the characters above adduced I conclude that this new species 

 of Palaeotheroid is more closely related to the true Palceotherium than 

 to Paloplotherium, and moreover it is the most primitive form of 

 yet discovered. 



I am not able to learn that the beds in which this skeleton was dis- 

 covered are any later than those in which the P. codiciense was found. 

 However, from the structure of the premolars in the two species, I 

 would conclude that P. codiciense came from an earlier subdivision of

 Plantes for having give
