2. Forms found together in certain geographical areas and 
not in other areas. Such groups may be called Sympatrie (ovv, 
together ; zatpa, native country). The occurrence of forms 
together may be termed Sympatry, and the discontinuous 
distribution of similar forms Asympatry. 
3. Forms which freely inter-breed together. These may 
be conveniently called Syngamic. (cvv, together; ydpos, 
marriage). Free inter-breeding under natural conditions may 
be termed Syngamy; its cessation or absence, Asyngamy 
(equivalent to the Amixia of Weismann). 
4. Forms which have been shown by human observation 
to be descended from common ancestors. Such groups may be 
called Synepigonic (cvv, together; éiyovos, descendant). Breed- 
ing from common parents may be spoken of as Lpigony or 
the production of Epigonic evidence.* 
My friend, Professor E. Ray Lankester, to whom I owe 
-so much, in this as in many other subjects, is inclined to 
think that we should discard the word species not merely 
momentarily but altogether. Modern zoology having aban- 
doned Linnzeus’ conception of “species” should, he considers, 
abandon the use of the word. In his opinion the “ origin” 
of species was really the abolition of species, and zoologists 
should now be content to describe, name, draw, and catalogue 
Jorms. Furthermore, the various groups of forms _ briefly 
defined above should be separately and distinctly treated by 
the zoologist, without confusion or inference from one to the 
other. The systematist should say, “I describe and name 
certain forms a, 6, etc.”; and then he or another may write 
a separate chapter, as it were :—“‘I now show that the forms 
ab, ac, ad (form names) are syngamic:” at another time he 
may give reason for regarding any of them as related by 
epigony. 
I fear that this suggestion is a ‘counsel of perfection,” 
impossible of attainment, although there would be many 
* My friend Mr. Arthur Sidgwick has kindly helped me by suggesting 
the appropriate Greek words. The use of éx/yoves I owe to my friends 
Mr. Arthur Evans and Mr. R. W. Macan. ‘The adjectival termination is 
made -ic throughout for the sake of convenience, although Sympatriote or 
Sympatrid would have been more correct.
