FOSSIL MAMMALIA. 89 



slender, and the bones of the nose analogously more minute. 

 It appears to have been, generally, lighter, more elevated and 

 less massive in the limbs than the species with partitioned 

 nostrils, and to have had the head less elongated. 



The third species is the rhinoceros with incisive teeth (rhi- 

 noceros incisivus). This rhinoceros is a species founded 

 solely on the discovery of some incisive teeth in Germany by 

 Camper. As neither the fossil rhinoceros with partitioned 

 nostrils nor the rhinoceros leptorhinus could have such teeth j 

 as their jaws aflPorded no lodgment for them, the Baron has 

 assigned them to a third species ; and though he has found no 

 other bones which he can positively refer to it, he does not 

 hesitate to inscribe it in the list of fossil animals. 



The last fossil species of rhinoceros is the minutus, also 

 provided with incisive teeth ; but its size could not much have 

 exceeded that of the hog, or one-third of that of the common 

 rhinoceros. This species rests on some teeth and divers 

 bones belonging to adult, and even old individuals, found in 

 1821 at St. Laurent, near the town of Moissac, in the depart- 

 ment of Tarn and Garonne, nearly seventy feet deep, after 

 having successively penetrated the vegetable earth, a strong 

 and compact marl, a bed of gravel, a bed of sandstone, and 

 many others of sand and gravel. The stratum containing 

 these bones had the appearance of our common river-gravel, 

 and also contained the bones of crocodiles and tortoises, and 

 many debris of adult rhinoceroses, some of the ordinary size, 

 and others two-thirds or one-half less. 



The state of these bones has led the Baron to conclude that 

 they may appertain to many different species, differing not only 

 in size, b'lt also in many other minute characters, which our 

 present limits will not permit us to detail.
