American species of Mammoth ; it was found fifteen feet deep in a stone 

 quarry near Welsbourn, Warwickshire, and is the tooth noticed in the 

 work on 'Organic Remains,' vol. iii. p. 345. Mus. Parkinson. 



601. A lower grinder of a Mammoth. In six inches extent of the abraded 



crown there are ten transverse plates ; all these are dilated at the middle 

 part of their exposed margins so as nearly to touch one another, and the 

 remaining interspaces are narrower and contain less cement than the 

 molars of the Indian Elephant ; the entire molar consists of seventeen 

 transverse plates. 



From the pleistocene brick-earth of Grays, in Essex. Hunterian. 



602. An upper molar of a Mammoth, with the crown cleft into fourteen plates 



in an antero-posterior extent of eleven inches. This grinder has been 

 slightly abraded by mastication at the anterior angle only, all the rest of 

 the tooth is invested by the thick outer coat of cement : it was dug out 

 of the brick-earth in the village of Grays in Essex, upwards of thirty 

 feet below the surface, and weighed eleven pounds : a few bones of the 

 Mammoth were found scattered about at a little distance from the tooth. 

 It agrees in character with the preceding Hunterian specimen ; and in 

 the smaller number and greater thickness of its coronal plates as com- 

 pared with the molars of the American Mammoth it corresponds with 

 that of Siberia, which makes a near approach to the existing Asiatic 

 Elephant in the modification of its molar teeth. Purchased. 



603. A portion of the back part of a large molar of a Mammoth, including 



five of the lamellar divisions of the crown in an antero-posterior extent 

 of one inch ten lines, the breadth of the plates being three inches. 



Locality unrecorded. Mus. Parkinson. 



604. The posterior part of a large molar of a Mammoth, including six of the 



lamellar divisions of the crown in an antero-posterior extent of two 

 inches six lines, the breadth of the plates being two inches five lines. 

 Locality unrecorded. Hunterian. 



605. An upper molar of a Mammoth. It is seven inches in antero-posterior 

 diameter, and includes sixteen plates, of which nine have come into use,
