'According to Smith the above, U. rerreauxianus Lea, africanus Lea, naialensis Lea, 

 and vaalensis Chapef, are all one species. I think he is right, but it seems to me that 

 one or two of these forms are worthy of varietal names. I have seen the types of 

 most and authentic specimens of all of them. 



s Said to come from the Columbia River, but it did not. 



3 Possibly a variety of N. caffer.
