•• While Boie designated Merrem's species as type of his genus Corytophanes, he did not actually print the 

 combination. That it was his intent so to spell the name is indicated in his article in vol. 21 (1828) of Isis 

 von Oken, p. 363, where he (Boie) spells the name Corytophanes. Kaup (Isis von Oken, vol. 21, 1828, p. 

 1147) does likewise.
