RHINOCEROS ETRUSCUS. 367 



Cast of right femur, figured by Cuvier, PI. XI. Ehin., fig. 19, of 

 which the upper articulating head is wanting 



Extreme length taken at the middle, 16 - 50 in. Anteroposterior diameter of 

 inner condyle and pulley, the latter partly broken, 6 - in. Length of pulley in 

 middle, 25 in. Transverse diameter of ditto, 2-5 in. Least transverse diameter 

 of shaft below the middle trochanter, 2'5 in. Vertical height of neck of middle 

 trochanter, 2 - l in. Transverse diameter of shaft, including middle trochanter, at 

 middle of ditto, 5'2 in. Width of bone at middle of sinus above middle tro- 

 chanter, 4 1 in. 



All these bones belong to Rhinoceros Etruscus, and there are still 

 preserved in the Bologna Museum, the originals of the specimens 

 represented by Cuvier, figs. 5 to 10, inclusive of PI. X., Rhin., of ' Os. 

 Fossil.' These are the upper and lower extremities of a humerus of 

 the same species (R. Etruscus), stated to have been procured by the 

 Ab. Ranzani in France. 



VIII. — Description of Specimens of Rhinoceros Etruscus at Le Puy. 

 Le Puy, 15th September, 1863. 



In the Museum of Le Puy there is a magnificent series of remains of 

 the skeleton, consisting of three feet, Avith all the bones en suite to the 

 terminal phalanges — the tibia, fibula, astragalus, and articular head of 

 the femur. The shaft of the femur with the third trochanter is exactly 

 as in Pentland's specimen in the British Museum. There are also two 

 detached calcanea, both of the left side, and one astragalus. All are 

 from Solilhac. 



In the same Museum there is also a series of the molars of R. 

 Etruscus, six right and left, but detached and separate, with the last 

 molar just coming into use, and in the finest condition for figuring. 

 They are from Vialette. In addition there is a superb specimen of the 

 left ramus of the lower jaw of R. Etruscus, having the four last molars 

 en suite, all a little worn, and the hind portion of the penultimate pre- 

 molar ; the teeth are in a beautiful condition to be drawn. 



There is also the muzzle of the lower jaw of R. Etruscus, perforated 

 below exactly like the specimen of Carlo Strozzi (see page 360), and 

 with the empty pits of two small median incisors more round, more pro- 

 nounced and less angular than in Strozzi's. There is no keel below, 

 as in ftie Florence specimen. The specimen is red, heavy and fer- 

 ruginous, and in the same mineral condition as the Vialette lower jaw. 



Dimensions of Lower Jaw, left, from Vialette. — Length of fragment, 11-5 in. 

 Length of series of four molars, 675 in. Length of last true molar, 17.5 in. 

 Length of penultimate, 1-65 in. Length of antepenultimate, 1-62 in. Length of 

 last premolar, 1-50 in. Height of jaw at posterior edge, last molar, 3-35 in. 

 Height at anterior edge of first true molar, 2-9 in. Height at anterior edge of last 

 premolar, 2'65 in. 



The inferior border is perfectly straight along the three true molars ; 

 there is no curve, but there is a strong longitudinal channel along the 

 middle of the inner side ; and to each of the anterior barrels of the four 

 molars there is an oblique descending bourrelet, strongly marked. The 

 jaw is truncated along the ascending ramus and in front. The specimen 

 ought to be figured.
