36 MAMMALIA. 



SUS PAL^EOCHCERUS, KAUP. 

 PLATE III., FIGS. 13, 14. 



The smaller Pig's teeth from the Nodule-bed of the Eed Crag 

 of Suffolk, which were identified as Sus palceoclmrus by Sir R, 

 Owen (Quart. Journ. Geol. Soc., Vol. XIL, p. 222, 1856), are 

 provisionally kept with that species ; and this determination is 

 in accordance with the opinions of Mr. R. Lydekker (Quart, 

 Journ. Geol. Soc., Vol. XLIL, p. 366, 1886). 



Sus palceochcerus was described from specimens found in the 

 Upper Miocene of Eppelesheim. 



SUS SCKOFA, LINNAEUS. 



(Wild Boar.) 

 (Vert. Forest Bed, p. 43. PLATE VI., FIGS. 4, 4a.) 



So far back as the year 1840 (Lyell, Phil. Mag., Ser. 3, 

 Vol. XVI., p. 345) the remains of the common Pig, Sus scrofa, 

 were known to occur in the Norfolk Forest-bed, and since then 

 several specimens have been found (Owen, Brit. Foss. Mamm. 

 p. 429, 1846), some of which are well preserved and show no 

 characters by which they can be separated from the living form. 



Sus scrofa is also known from Pleistocene and Prehistoric 

 deposits, and is now living in the temperate zone of Europe. 



PERISSODACTYLA. 

 Genus EftUUS, Linnaeus. 



EQUUS CABALLUS, LINNAEUS. 

 (Vert. Forest Bed, p. 30. PLATE VII., FIGS. 1-8.) 



In the Survey Memoir Prof. Riitimeyer's name ofEquus caballus 

 fossilis was used for the fossil horses, the remains of which 

 could not be distinguished from the recent forms ; it is now 

 thought better to follow Mr. R. Lydekker (Cat. Foss. Mamm. 

 Brit. Mus., part iii., p. 73, 1886), and to refer these fossils to the 

 recent species Equus caballus until such time as they can be shown 

 to be specifically distinct. Prof. Flower (Cat. Vert. Roy. Coll. 

 Surg., part ii., p. 408, 1884), in referring similar specimens, 

 places a query after E. caballus f 



The equine remains from the Norwich Crag, noticed by Sir 

 R, Owen (Brit. Foss. Mamm., p. 390, 1846), in Mr. Fitch's 

 collection, and referred to E. fossilis, are provisionally included 

 with E. Stenonis, which is known to occur in these beds.
