Sir, — Reference has already been made by me to the above subject in 
the pages of the 'Geologist.'* The nomenclature which I have used, and 
the inferences which I have drawn, having been impugned in an elaborate 
paper by Dr. Falconer,t a few lines in their justification may be permitted. 
When, in February, 1858, the tooth in question was shown to me by my 
friend Mr. Bollaert, the most casual observation was sufficient to demon- 
strate that it was of a different species to the Mammoth (E. prijn I genius). 
In the dearth of published information on the subject I consulted the 
works of Cuvier,;}: Humboldt, § Leidy, |{ De Blainville,^ Carpenter,** 
Lartet,tt and others, and especially the memoir of Dr. Falconer. [j:;]: I en- 
deavoured in the paper on the Texan Elephant to acknowledge the benefits 
to proboscidean science derived from his "most complete, elaborate, and 
philosophical conspectus." 
Upon attempting, with the "Bollaert molar" in my hand, to discover in 
this memoir any specific -description of this form, my efforts resulted in 
disappointment. Dr. Falconer, in the above-cited memoir, divided his 
subgenus JSnelepIias into four divisions. The first he characterizes as 
having " Colliculi ^uhre/iwti, adamante crassiusculo." The solitary species 
belonging to it is the Miocene E. Hysudricus. The second division [Col- 
liculi approximati. medio leviter dUatati, machceridihus undulatis) includes 
E. antiquus and E. Namadicus. The third division (CoJliculi opproxi- 
mati, machcsridihus valde undulatis) includes E. Columbi, E. Indicus, and 
E. Armeniaeus . The fourth division (Colliculi conferfissimi, adamante 
valde aitemiato, mach(Eridihus vix undulatis), has for its solitary represen- 
tative the mammoth {E. primirfenius). 
The name E. Columhi has the following notes added to it in Dr. 
Falconer's Synoptical Table : —

Alabama. vol. xxxiv. p. 363. 
In the second part of his paper, which was read before the Geological 
Society on June 3, 1857, §§ Dr. Falconer concluded with a few remarks 
on the non-existence of E. primigenius south of the Alps, and its restric-
