FALCONER MASTODOIT AND ELEPHANT. 325 



tion at Banwell, and one in the collection of the Geological Society, 

 from Kent's Hole. The displayed part of the collection in the 

 British Museum contains a few examples of this tooth referable to 

 the Mammoth, and it exists also in the collection of the College of 

 Surgeons, The crown, as in the corresponding tooth of the Indian 

 Elephant, is composed of seven or eight ridges, with, talons. A fine 

 specimen, in the Museum at Taunton, from one of the Mendip 

 caverns, in perfect preservation, with the fangs present and the 

 crown worn, presents seven principal ridges, besides front and hind 

 talons. 



The dimensions are — inches. 



Length of crown , 2-3 



Width of crown at second ridge 0-9 



Greatest width behind 1-4 



From the dimensions it will be seen that the crown is narrow in 

 front and broad behind, yielding somewhat of an ovate outline. 

 The specimen in the collection of the Geological Society, from 

 Kent's Hole cavern, is a penultimate upper milk-molar of the right 

 side, with the crown much worn and the anterior portion ground 

 out. The disks of the six posterior ridges remain. 



The dimensions are : — inches. 



Length 2-2 



Width behind , . . . 1-3 



The specimen (no, 583 of the Cat. Foss, Mam.) in the Museum of 

 the College of Surgeons is a left upper maxillary, containing the 

 penultimate milk-molar far advanced in wear. The crown in this 

 ease is also much worn, presenting the disks of six principal ridges 

 and a hind talon. The specimen is reputed to be from the Drift- 

 beds at Ilford. 



The last mUk-molar, or third in succession, of the upper jaw of 

 E. primigenius, abounds in English collections, both from the 

 caverns and from the Drift-beds. It is readily distinguished from 

 the same tooth in the other species, fossil or recent, by the broad 

 squat form of the crown and the closely approximated ridges and 

 imcrimped enamel plates, A fine illustration of this tooth is pre- 

 sented by the Hunterian specimen (no. 585, Cat, Fossil Mam.) in 

 the Museum of the College of Surgeons, from Hinton, Somersetshire, 

 The crown is composed of eleven principal ridges, with talons, the 

 anterior part being sHghtly worn, showing the disks of five or six 

 ridges ; the posterior ridges are intact. 



The dimensions are — inches. 



Length of crown 3-6 



Width in front 1-5 



Greatest width ,.,, 1*8 



Height at sixth ridge 2-6 



The ridges are closely approximated, and the attenuated layers of 

 enamel free from crimping. Id the descriptive catalogue (p, 140), 

 the crown is regarded as being composed of twelve plates, the last 

 being here considered the posterior talon.
