'According to Smith the above, U. verreauxianus Lea, africanus Lea, natalensis Lea, 

 and vaalensis Chaper, 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 

 roost and authentic specimens of all of them. 



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



^Possibly a variety of N. caffer.
