" The author of this generic name, and of the specific name as well, has been accepted as Gray by some 

 authors, as Wiegmann by others. Wiegmann pubhshed his own description in 1831, in great detail; Gray 

 published but a few words, also in 1831, but attributed both names to "Wiedemann, MSS" (in error; = 

 Wiegmann). Even though Gray's description may have preceded Wiegmann's, it seems obvious that 

 Wiegmann was ethically the author, having provided the only reasonable description, and his manuscript 

 having been acknowledged by Gray as the source of the latter's information. It is true that Gray stated 

 specimens were in the British Museum (Boulenger cites one purchased by Gray), so that Gray could well 

 have drawn up his description from them and not from Wiegmann's manuscript. The correct authorship 

 thus remains debatable. 



M Wiegmann cited Chamaeleo Mexicanus of HernSndez in both of his papers (1831 and 1834) but did not 

 adopt the name.
