cial cracks (sun-cracks?) on its crown and sides. The weathered state 

 of the tooth and its weight a'nd hardness clearly prove its fossil con- 

 dition, although the black alveolar-margin stain still borders the 

 sides of the crown, as represented by the brown paint on the cast. 

 The weight equals 3| lbs. 



This penultimate true molar, right side, upper jaw, although par- 

 taking of the characters of ^. Armeniacus, Pale, differs from the 

 latter in its thick plaits, their less approximation, the festooning 

 being carried round the loops of the disks of wear, and the total ab- 

 sence of any mesial expansion. 



There is a notice of a fossil elephant's tooth mentioned in the 

 slate work on Japan by Sir Eutherford Alcock. I can find no record 

 of the animal having existed in recent times in Japan ; and consi- 

 dering the importance of the subject as connected with the Elephant 

 of Asia, I herewith forward an exact cast of the molar, now in 

 the possession of Dr. Piske, of St. John, New Brunswick, in the hope 

 that futui'e inquiries may be made regarding such an interesting 

 -discovery as that of the Asiatic Elephant in a fossil state. 



A^DDiTiON^AL Bemakks. By G. Busk, Esq., E.E.S., F.G.S. 



The foregoing brief notice and the accompanying cast having been 

 recently sent to me by Dr. Leith Adams, I have hastened to lay them 

 before the Society, fully agreeing with Dr. Adams as to the interest 

 attaching to the discovery he records, and especially if, as seems 

 highly probable, he is right in referring the fossil to E. Indicus. 



With reference to the latter point, I beg to offer one or two 

 remarks. In the British Museum there is a large part of a 

 fossil molar tooth from China, which, on comparison with the teeth 

 presented by Colonel Gills from Armenia, so exactly resembles them 

 in every respect, that no doubt can be entertained as to its belong- 

 ing to the same species, namely, E.Anneniacus of Dr. Ealconer; and as 

 such, I believe, it was regarded by that eminent palseontologist. The 

 occurrence, therefore, of the same form in Japan would not have 

 been very surprising ; but, so for as I am able to judge, it is im- 

 possible to identify Dr. Duggan's specimen with E. Armeniaciis. In 

 the first place, a,s pointed out by Dr. Leith Adams, the crimping 

 of the enamel extends quite round the ends of the disks, and is not 

 limited to the middle portions of them only, as it is in the typical 

 E. Armeniacus ; and, secondly, the Japanese tooth is at least an 

 ineh narrower tlian those from China and Armenia, or than those 

 described by Dr. Falconer as belonging, in all probability, to the 

 same species, and observed by him in Italy. 



The only other species with which any comparison need be made 

 is Dr. Falconer's E. Columhi, with some specimens of which, as de- 

 scribed by him, the dimensions of the Japanese tooth appear to 

 accord, although the majority of teeth of E. Columhi seem to be 

 much wider. The tooth is much curved, a character upon which 

 Dr. Falconer lays much stress in his account of E. Columhi. But 

 it differs from that species in the apparently less thickness of the
