120 BRITISH FOSSIL ELEPHANTS. 



Another lower ultimate tooth in the British Museum, from Walthamstow, Essex, 

 holds twenty-two plates in 10^X3 inches and eight in 4^ inches. This a thick-plated 

 molar, but the cement is also in excess. 



A lower ultimate in the British Museum, from the Thames near BRENxroRD, Mid- 

 dlesex, has twenty-one of the anterior ridges remaining in 11 X 2^ inches, and contains eight 

 in 5 inches. The plates are very thich, with much cement. The crown is narrow and 

 much arcuated. 



A mutilated lower ultimate molar, holding a? 18, from the "post-pliocene," Dartford, 

 Kent, is in the Museum of Practical Geology. It is noteworthy for its very thick plates 

 and crimped enamel ; the latter, however, is not abnormal as regards thickness, but the 

 dentine and, chiefly, cement are in excess. 



An imperfect crown from gravel at Chesterton, Cambridgeshire, in the Wood- 

 wardian Museum, presents thin enamel, which is crimped. There are from twenty to 

 twenty-one plates, besides a posterior talon, in 8^x3 inches, and eight ridges are con- 

 tained in a space of 2*8 inches. There is also a fragment of a tusk from the same 

 locality. The molar contrasts, as regards the thickness of its plates, with a milk molar 

 from the same situation, described at p. 97, whose plates are decidedly thick, whilst 

 both indicate small individuals of their respective ages as is seen in the Ilford 

 molars. 



The Museum of Zoology, Cambridge, contains a fragment of an ultimate molar 

 holding fourteen collines in 7 X 3 inches. It is interesting as being from Whitby, in 

 Yorkshire. The crown is typical. 



The same collection contains a fragment of a true molar from Wenden, in Essex, with 

 a typical crown pattern, and another fragment from " valley gravel," Booking, Essex, 

 with rather thick enamel ; also a piece of a last molar from Buxton, Derbyshire, and also 

 a broken tooth from gravel at Kensington, London, containing eight ridges in 3^ inches. 

 The plates in the last-named tooth are rather thich, with the enamel like that in Ilford 

 molars, whilst two other specimens from the "brick-earths" at Sittingbourne, Kent, 

 are //«';2 -plated, both the enamel and cement being thin. 



An incomplete true molar, possibly an ultimate, recorded from " Compton Bay, Isle 

 of Wight (Forest Bed)," is in the Jermyn Street Collection. It is ^/«'cZ;-plated at the 

 expense of the enamel, which is inordinately thick. There is also a germ of either an 

 ultimate or penultimate in the same collection from " Freshwater Gravel, Chale Bay, Isle 

 of Wight." The characters of this tooth are not determinable with certainty. 



A fragment of one or other of the last of the series from Kent's Cavern is in the 

 British Museum. It shows, as has been already noted, thin enamel (p. 94) with faint 

 crimping of the disks. 



There is an imperfect right lower last true molar from Barrington, in the Wood- 

 wardian Museum, Cambridge, containing 17 x in llXSf inches. All the elements of 

 the crown are in excess, the cement in particular, and the disks present crimping with
