I really believe you are slightly color blind".^^ Tavemer argued that he was not, and wrote, "I do not think I am color blind.

"I may not always write perfectly clearly but I do not think you read any too carefully. At least you misunderstand a number of things I have ;^" Early in 1922 Taverner wrote a letter to the lead- ing systematics research workers of the AOU enclos- ing a statement protesting against what he consid- ered was the debasing of the concept of genus in ornithology by the proliferation of subgenera. He claimed that the tendency towards the finer division of the genus threatened to complicate nomenclature and taxonomy until each group in a genus became the private preserve of specialists in that group. He asked recipients of the statement to read it carefully, and return it with their opinion.^' Taverner must have known that he was "sticking his neck out" reck- lessly.
