*'This category may be in so far almost indefinitely extended since I have shown 

 that all grades of similarity exist, from undoubtedly different, but congeneric, to un- 

 doubtedly identical species. I have only included forms which run very close, about 

 some of which perhaps naturalists are not clear whether they are the same or different. 

 In the discussion of these it is to be regretted that much unscientific temper has been 

 displayed, but that is the fault of that amateurism which Dr. Packard so deprecates. 



t These are probably identical species.
