LARTET — BONE-CAVE IN MARITIME ALPS. 11 



in the two preceding fossil species, with which U. Bourf/uif/natl has 

 been compared, they approach one another behind), the diastema 

 between the two simple premolars is longer, and premolars 3, 4, true 

 molars 1, 2, occupy less space in the alveolar edge, while their trans- 

 verse diameters are greater. In the carnassial tooth, the internal 

 talon is smaller, and instead of being raised by a stout tubercle, it 

 presents normally only low rounded bosses on a base but slightly 

 extended backwards. 



Felts leopardus ? var. fossilis (Lartet). — The skull of the Felis is 

 about the size of that of the largest panthers of Africa. It ap- 

 proaches in its dimensions the skull of the variety living in Mo- 

 rocco, but still more closely the variety now found at the Cape of 

 Good Hope. There are, however, appreciable differences observable 

 between the fossil and the recent form. The canines of the fossil 

 are longer, and their sillons are deeper. The lateral incisor has a 

 stronger, the second a weaker fang. The small mono-fanged pre- 

 molar has its crown smaller, less compressed, and disposed more 

 obliquely to the alveolar edge ; it is also nearer the canine and 

 isolated somewhat from premolar 3. The latter is stouter than 

 in the Cape leopard, thicker behind, where its basilar cusp rests on 

 a stoutly developed talon. The accessory anterior is situated more 

 on the inside. The fourth premolar, or carnassial, is equally larger 

 in its proportions ; its talon is less detached from the anterior blade 

 than in the existing leopard. The true molar was implanted by two 

 fangs ; but as its crown is broken, it is impossible to say whether 

 it presented any differences. In the panther of Morocco, the space 

 occupied by the molar series is the same as in the fossil. The small 

 anterior premolar has its crown directed at a greater angle to the 

 alveolar border, and the premolar 3 has a greater antero-posterior 

 extent, and is without the small anterior accessory cusp. 



These differences of proportion do not seem to M. Lartet suffi- 

 ciently important to prove that the Fells of the Cavern of Mars be- 

 longs to an extinct species. 



Wiinoceros Merhii (Kaup). — Associated with the two preceding 

 skulls were the remains of a Rhinoceros, which have led M. Lartet to a 

 most important inference about the nomenclature of one of the four 

 Pleistocene species found in Great Britain. In the year 1839*, Jager 

 figured, under the name of R. Kirherhergensis, teeth found in Baden 

 and Wiirtemberg ; two years afterwards, in 1841, Dr. Kaupt de- 

 termined the species, and changed its name into R. Merhii. In 

 1846 j. Professor Owen described the remains of a Ehinoceros vnih. 

 a demicloison, from Clacton, as belonging to 7^. le^^tovliinus of Cuvier, 

 or the Phinoceros without a cloison. Duvernoy proposed provision- 

 all)^ in 1853 §, for the remains at Clacton the name oi R. protkJio- 

 rhinus. About the same time M. Gervais||, lighting on the so-called 

 R. minutiis of the cave of Lunelviel (described in 1834 by MM. do 

 Serres, Dubreuil, and Jeanjean), imposed the name of i?. LuneUensis.
