I I4 THE AMERICAN NATURALIST. [Vor. XXXV. 
not in the ordinary perfunctory manner for the mere naming 
and labeling of museum specimens. The time has come when 
the interrelationship and the sequence in time and space of 
the various subspecies must be studied. A perusal of Tke 
History of the European Fauna should make clear to the 
average describer and namer of animals that his work is only 
the means to an end. It brings before him the very 
problems for the solution of which his work is necessary, 
and the more conscious he becomes of the uses to which it 
is to be put, the better and more reliable it is apt to be 
performed. 
I do not know whether Dr. Scharff is to be commended or not 
for having withstood the temptation to correlate the immigra- 
tion of man into Europe with that of the other post-Pliocene 
mammals. The wanderings of the plants are alluded to in 
order to strengthen the views expressed relating to the origin 
of the fauna. The travels of primitive man must to a great 
extent have followed much the same lines as the other mam- 
mals, the same natural barriers being nearly as effective in his 
case as in theirs. It might be said that it would require 
volumes to exhaust this subject alone, but that is almost 
equally true of all the various groups of animals. Then again 
it might be objected that our knowledge of the wanderings of 
prehistoric man in Europe is very limited and uncertain. I 
think, however, it can be safely asserted that it is not any 
more so than our knowledge of the migrations of the animals 
and plants in the same period, and I venture to suggest 
that there is a remarkable similarity between the migra- 
tions we have discussed above and those of the various 
European subspecies of man. 
The first point to be observed is that the dolichocephalic 
brunet Mediterranean, or Atlanto-Mediterranean, race in its 
distribution both in time and space clearly corresponds to Dr. 
Scharff’s “ Lusitanian fauna," The agreement is not only a 
general one, but in some details almost startling, as seen if one 
compares, for instance, Scharff’s map on page 7 with any map 
showing the distribution of the brunet type in the British 
Islands.
