To Albert Günther 13 May 1
Down, | Beckenham, Kent.
My dear Dr. Günther
Will you have the kindness to answer me a simple question. Is the Horned Toad, of Oregon, the Tapaya Douglassii, a Batrachian or Lizard? I ask because I believe that the the Horned Frog of California, the Phrynosoma Cornuta is a Lizard.— If the names are synonyms, which is right; & have I spelled them rightly?2
I shall be anxious to hear, as I sincerely hope may be the case, that you are successful about promotion in B. Museum. I do not know whether I judged wisely but I thought my form of Testimonial would be the best for the Trustees, as many of them know nothing of science, but wd. regard a European reputation.3
Yours very sincerely | C. Darwin
