340 MOSTLY MAMMALS 
the Indian Ocean in a state of nature we know practically 
nothing, owing to the fact that in South Aldabra alone 
are any members of the group living in a wild condition, 
and that accurate observation is there practically impos- 
sible. Of the mode of life of the Galapagos species we 
have comparatively full accounts; but limitations of space 
render it impossible on the present occasion to refer 
further to these species, either as regards their distinctive 
characteristics or their history and habits. I have only 
to add that readers of this volume are indebted to Mr. 
Rothschild for the loan of the photograph illustrating 
this article.
