UNGULATA. 35 



occurs 'in the Pliocene of France and Italy; and is now living 

 in Africa south of the Sahara. 



Genus SUS, Linnaeus. 



The teeth of Pigs from the Red Crag of Suffolk, which were 

 known in the year 1846, were not at that time specifically named 

 by Sir R. Owen (Brit. Foss. Mamm., p. 427), but in 1856 (Quart. 

 Journ. Geol. Soc., Vol. XII., p. 222) he referred them to two 

 species, Sus palceo cheer us, Kaup, and S. antiquus, Kaup. Prof. 

 Lankester in 1864 (Ann. Mag. Nat. Hist., Ser. 3, Vol. XIV., 

 p. 359) quoted the same two species ; but in 1870 (Quart. Journ. 

 Geol. Soc., Vol. XXVI., p, 510) he seems to have doubted the 

 correctness of this identification as he merely gives Sus sp. More 

 recently Mr. R. Lydekker (Cat. Foss. Mamm. Brit. Mus., Part ii., 

 pp.268 and 273, 1885; Quart. Journ. Geol. Soc., Vol. XLIL, 

 p. 366, 1886), has thought it possible that the larger teeth may 

 have belonged to Sus erymanthcus ; at the same time he retains 

 provisionally the name of Sus palceochoerus for the smaller Pig's 

 teeth of the Red Cra. 



Messrs. R. and A. Bell (Proc. Geol. Assoc., Vol. II., p. 208, 1872) 

 give Sus arvernensis as a Red Crag form ; but there is no 

 sufficient reason for acknowledging a third species in the Crag. 

 Mr. J. Gunri (Geol. Mag., Vol. VI., p. 237, 1869) recorded the 

 occurrence of Pig in the Coprolite bed below the Coralline Crng, 

 at Sutton. 



There are two portions of lower tusks of Sus from the Red 

 Crag in the Reed collection, York Museum, one from Wood- 

 bridge, and the other from Waldringfield, and there is an incisor 

 in the Canham collection at Ipswich. 



SUS ANTIQUUS? KAUP. 

 PLATE III., FIGS. 11, , b, 12, , 6. 



The larger Pig's teeth from the Red Crag, which were referred 

 by Sir R. Owen (Quart, Journ. Geol. Soc., Vol. XII, p. 222, 

 1856) to Sits antiquus, are provisionally retained in this species. 

 Although it is possible they may belong to S. erymanthcus, as 

 indicated by Mr. R. Lydekker (Quart. Journ. Geol. Sou., 

 Vol. XLIL, p. 366, 1886), yet it is not certain that such an 

 allocation would be correct, and of two uncertain names it seems 

 best to keep the one which has been so long in use, rather than 

 introduce another equally uncertain. Sus antiquus is only known 

 in Britain from the Nodule-bed of the Red Crag of Suffolk. Tne 

 type described by Kaup was from Upper Miocene Beds at 

 Elppelsheim. Sus erymanthetis was found in the Lower Pliocene 

 strata of Pikermi.
