o Malherbe claims (Mon. Pic, ii, p. 245, footnote) 1853 as the date of his specific 

 name "kaupii," on the ground that Bonaparte instituted the name "en effet" by 

 dedicating it, in the Revue et Magazin de Zoologie for that year, to "au savant directeur 

 de Musee de Darmstadt." Inasmuch, however, as not even Dr. Kaup'e name was 

 given in the passage quoted as evidence, it will readily appear that Professor Baird 's 

 specific term uropygialis was really the first proposed.
