584 Fossil Remains of Anoplotherium 



Second Fossil Species of Giraffe.— The fossil specimens next to 

 be described have been in the possession of the authors ever since 

 1836. They are fragments from the upper and lower jaws of an- 

 other fossil species of giraffe, in which the teeth are so exactly of 

 the same size and form with those of the existing species, and so 

 perfectly resemble them in every respect, that it requires the calipers 

 to establish any difference between them. 



The largest specimen is a fragment of a left upper jaw containing 

 the two rear molars. The back part of the maxillary, beyond the 

 teeth, is attached, and clearly proves that they belonged to a full- 

 grown animal. These teeth were compared with the teeth, in the 

 same stage of wearing, contained in the head of an adult female 

 giraffe belonging to the museum of the College of Surgeons, and 

 the fossil and recent teeth were found to agree together in the 

 most minute particulars. The following are the corresponding dimen- 

 sions of the fossil and recent teeth : — 



Fossil. Recent. 

 Inches, inches. 



Joint length of the two back molars, upper jaw, ... 2-5 2-55 



Greatest width of last molar, ... ... ... 1-4 1-3 



Ditto ditto of penultimate molar, ... ... 1-45 1*35 



Five other specimens are next described in detail by the authors. 

 They are all of them fragments of jaws and teeth more or less com- 

 plete upper jaws, corresponding exactly in size and form with that 

 of the left side, but if anything, rather more worn, and belonging 

 therefore, probably, to different individuals. The agreement extends 

 down to the small cone of enamel at the base of the hollow between 

 the barrels on the inside. Its dimensions are : — 



Length 1*2 inches. 



Width 1-4 



The third specimen is a fragment of the left lower jaw, containing 

 the last molar. It has precisely the form and proportions of the 

 corresponding tooth in the left lower jaw of the female head referred 

 to, and the same development of its third barrel or heel, which is 

 always found in this tooth in ruminants. Its dimensions are : — 



Length. . . ; 17 inch. 



Greatest width 1*0
