Of course any comparison between Kansas and New Mexico, even 

 were the lists complete, would fail to bring out the exact nature of 

 the facts, since Kansas contains at least two different fauna?, and New 

 Mexico several. The thing to do now is to accumulate data as rapidly 

 as possible, so that a detailed comparison of all the faunne and 

 faunulae may be made.
