ELEPHANTID^J. 27 



France, and is preserved in the Museum of Natural 

 History at Lyons ; it is figured by Lortet and Chantre, op. 

 cit. pi. xi. fig. 4 1 . 



The following specimens may perhaps belong to the present species. 



42089. Fragment of an upper (?) true molar ; from a gravel-pit at 



Swaffham, Norfolk. This specimen is noticed by Lan- 



kester in the Quart. Journ. Geol. Soc. vol. xxvi. p. 509 



(1870). Presented by C. B. Rose, Esq., 1871. 



42720. The last two ridges and talon of a third lower true molar ; 

 from the Red Crag of Sutton, Suffolk. Purchased, 1871. 



Mastodon turicensis, Schinz 2 . 



Syn. Mastodon tapiroides, auct. 



Tetrabelodon turicensis, Cope 3 . 



Since there is a great probability that the name Mastodon tapi- 

 roides, Cuvier 4 , was applied to milk-molars of M. angustidens 5 , 

 Schinz's name is adopted for the present species. 



According to Lartet 6 the upper incisors are furnished with an 

 enamel-band, while the mandibular symphysis is elongated and 

 carries a pair of incisors 7 . The ridges and valleys of the cheek- 

 teeth extend straight across the crown, accessory tubercles being 

 absent, and one column of each ridge wearing into an imperfect 

 trefoil ; their crowns are relatively narrow, and the ridges tall and 

 inclined ; a strong cingulum exists in the upper molars, and those 

 of both jaws have small, multicuspidate talons. The "inter- 

 mediate " molars very closely resemble those of M. americanus ; 

 while the milk-molars are almost indistinguishable from those of 

 M. angustidens. Premolars were developed 8 . 



Hob. Europe (France, Germany, Austria-Hungary, and Eussia). 



33589. The first left upper true molar ; from the Middle Miocene of 

 St. Gaudens (Haute-Garonne), France. This specimen 

 agrees very closely with the tooth figured by Lortet and 

 Chantre in the Arch. Mus. Lyon, vol. ii. pi. viii. fig. 3 

 (1878). Purchased, 1858.
