Until a satisfactory revision of the African elephants, based upon 
the material contained in all of the museums of the world, has been 
made, it will be impossible to say how many of the described forms 
are really distinct, or to allocate specimens to them with any degree 
of accuracy. There are unquestionably a number of valid subspecies 
and nothing is to be gained, at present, by grouping specimens under 
one name if they can be fairly well sorted geographically under the 
various described races. The actual distinguishing characters of the 
subspecies are imperfectly known, as the forms have been described 
on different features of the anatomy, without comparison of proper 
material.
