inches below the plane of the crown, is thirteen and one half inches. 

 The greatest width of the crown is at the third plate, where it is 

 three and one fourth inches. It becomes slightly narrower back- 

 wards. At two inches below the plane of the crown the width is 

 three inches and seven-eights. There are twenty-six plates, including 

 two incomplete ones at the posterior extremity. The nine anterior 

 plates have been brought into view, and the next two are partially 

 exposed. The nine worn plates occupy a length of four inches, 

 giving an average of a little less than half an inch for each. Fiom 

 the manner in which the plates diverge below the crown, the 

 average width at half the depth of the tooth, as exhibited by the 

 ridges on the side is a little more than half an inch. The

enamel plates are thin and not crimped, and both the dentine and 

 the cement are worn out to the depth of one or two lines below 

 them. The height of the tooth at the mid-length is about seven 

 one half inches. In front of it there is an empty fang-pit, four 

 inches in depth, separated from the main body of the alveolus by 

 a thick transverse wall. The tooth is gently curved sideways, 

 having the concave curve outside. The last or posterior plate 

 consists of only three digitations. The next in front of it, of six 

 and the third of seven. 



The next specimen to be described is a symphysis (Fig. 4 & 5), 

 evidently belonging to a much larger animal. The length along 

 the median line on the under surface is six one-fourth inches 

 including the mandible, which is two and one-fourth inches in
