4891.] The Origin of the Galapagos Islands, 229 
restricted in distribution. I think it possible to trace the “ original ” 
locality of each species of this genus. 
If we now compare the results we have reached about the dis- 
tribution and variation of birds and reptiles, we must admit that 
we have found absolute harmony. 
We find exactly the same in regard to the flora, but unfortu- 
nately only five islands of the central group have been examined, 
and that but little——-Chatham, Charles, James, Indefatigable, and 
Albemarle. All that we know of the flora of Indefatigable, 
for instance, was collected in a few hours by Andersson. All these 
islands reach into the humid region. Great results doubtless will 
be found when the northern and southern islands have been 
studied, and also the lower ones of the central group, like Barring- 
ton and Duncan, for instance. The peculiar genera found in the 
Galapagos are representcd by peculiar species on the different 
islands ; and the same is true for the non-endemic genera. 
(To be continued.)
