In my article with the above heading, to which my friend Mr. J. B. Smith takes exception, I at once confess that an error occurs, and that the title should have been new to “our lists” and not to “our fauna.” Mr. Smith wrote me a day or two after the publication of the paper, and I at once replied that I should have used the word “lists” in the place of “fauna.” I am therefore somewhat surprised that in his printed remarks he did not allude to the correction 'I had personally made, but that he should take me to task after receiving my letter, and charge me with adding the species mentioned to our “fauna,” when I had disclaimed the meaning he attributes to me.
