UNGULATA. 



elongated and deflected, and carries a pair of short, subcylindrical 

 incisors. The columns of the cheek-teeth are separated by a deep 

 longitudinal cleft, but are arranged in the same transverse line ; 

 the accessory tubercles are of moderate size, and one column of each 

 of the earlier ridges wears into a distinct trefoil ; the valleys are 

 but slightly blocked, and do not contain any appreciable amount of 

 cement. Premolars are present. The last upper true molar usually 

 has a large and complex hind talon ; the inferior border of the man- 

 dibular ramus is highly convex, and the incisive alveoli diverge 

 anteriorly. 



Hah. Europe (England 1 , Germany, Erance 2 , and Austria-Hun- 

 gary 3 ). The English specimens are from the Red Crag. The 

 species occurs in the ossiferous sands of Eppelsheim and the 

 Congerian stage of the Vienna basin; and is thus of the same 

 homotaxial age as M. cautleyi of the Pliocene of Western India. 



M. 2907. Cast of the palatal half of the cranium, showing the 

 second and third true molars of either side. The original 

 was obtained from the bone-sand of Eppelsheim, Hessen-

 Oss. Foss. d. Darmstadt, pt. 4, p. 75, pi. xvi. fig. 5, 

 and pi. xix. fig. 1 ; it forms the upper half of the specimen 

 figured in woodcut, fig. 15. Purchased. 



M. 2908. Cast of the palate, showing the much-worn m. 1 on the 

 right side, and the little-worn m- 2 of both sides. The 

 original is from Eppelsheim, and is described and figured 

 by Kaup, op. cit. p. 74, pi. xvi. fig. 4. Purchased. 



21485. The palate, showing m. 2 of either side in an early condition 

 of wear; from Eppelsheim. Purchased, 1847. 



M. 2909. Cast of a portion of the left half of the cranium of a young 

 individual, showing the three milk-molars, of which the
