DESCRIPTION OF PLATE XXII. 



Bhinoceros Etruscus. 



Figs. 1 and 2. Represent in profile and plan the greater part of the 

 horizontal ramus of the left side of the lower jaw, with the three 

 true molars in situ, and the empty alveoli of the three last pre- 

 molars. The specimen is in the collection of the Rev. John 

 Gunn, of Irstead, and was found in the Forest-bed of the Norfolk 

 Coast. The drawings are about two-fifths (-£%) of the natural 

 size (the length of crowns of three teeth at inner edges being 

 5-1 inches), and have been executed by Mr. Dinkel from the 

 original specimen which was forwarded to London for the pur- 

 pose by Mr. Gunn. (See page 345.) 



Fig. 3. Represents a specimen also from the Forest-bed of the Norfolk 

 Coast, formerly in the collection of the Rev. James Layton, and 

 now in the British Museum (Cat. No. 33,326). It is a frag- 

 ment of the left ramus of the lower jaw, containing the last 

 premolar, the first two true molars, and the anterior fang of the 

 last molar. The drawing is about two-fifths of the natural size, 

 and has been executed by Mr. Dinkel from the original speci- 

 men. (See page 3-45.) 



Fig. 4. Is a fragment in the British Museum (Cat. No. 28,802), from 

 the Val d'Amo ; showing the alveolar portion of the left ramus 

 of the lower jaw, containing the last premolar and the three true 

 molars in situ. The drawing is about one-third of the natural 

 size, and has been executed by Mr. Dinkel from the original 

 specimen. 



Fig. 5. Represents the first true molar, upper jaw, left side. The figure 

 is three-fourths of the natural size, and has been copied from 

 a drawing made for Dr. Falconer, and on which he had written : 

 ' Rhinoceros Etruscus — t. m. 1. 1. Happisburgh. The Rev. 

 J. Gunn. Coll. Yarmouth Museum.'
