332 PEOCEEDU!fGS OP THE GEOLOGICAL SOCIETY. 



The specimen is labelled as being from the Ohio, and when ap- 

 plied to the maxillary fragment, no. 620 in the same collection, 

 containing the upper antepenultimate described anted, p. 328, the 

 crown-surfaces fit so exactly, and the two specimens agree so closely 

 in size, relative progress of wear, and in general appearance, that 

 it is highly probable that they belonged to the same individual. 

 They both present the black surface which is so common in the 

 Elephant- and Mastodon-remains from the Bone-licks of the Ohio. 

 Another illustration of the same tooth is seen in the young man- 

 dible (Coll. Brit. Mus.) represented in the ' Fauna Antiqua Siva- 

 lensis,' pi. 13 a. fig. 2, which contains the antepenultimate on both 

 sides, well advanced in wear, but complete, and the penultimate 

 in germ behind. The crown of the antepenultimate is composed of 

 twelve principal ridges, with talons, aU of which, except the pos- 

 terior talon, are afifected by wear; it is broad relatively to the 

 length, although in a less degree than is seen in the previous speci- 

 mens ; the disks of wear form closely compressed transverse bands, 

 with attenuated plates of enamel. It is deserving of remark, that 

 some of these plates differ from the ordinary type of the Mammoth 

 in exhibiting a certain amount of irregular crimping, but in no 

 degree approaching that seen in the Indian Elephant, the presence 

 of this character being concurrent with -a less than the ordinary 

 width of crown. 



The dimensions of the tooth are : — 'nches 



Length of crown 5*3 



Width in front 1-85 



Greatest width 2*3 



In a specimen in the Museum at Turin the dimensions are : — 



inches. 



Length of crown 5-2 



Width in front 1-9 



Greatest width 2-4 



In the Museum of Taunton, so rich in remains from the Mendip 

 caves, there is a finely preserved detached antepenultimate lower 

 molar from " Wookey-hole," found along with teeth of the Siberian 

 Rhinoceros, Cave-lion, and Hysena. The crown, although worn to the 

 extent of seven or eight disks, is complete, and composed of twelve 

 ridges, with front and back talons ; it is broad and squat-looldng, 

 with aU the usual typical characters of the Mammoth, i. e. narrow 

 transverse disks with thin unplaited enamel. 



The dimensions of this specimen are — . , 



Length of crown 5-1 



Width of crown in front 2-3 



Height at the eighth ridge 3-5
