In the Erpetologie yenerale this snake is placed in the 

 genus Coronella. I examined the dentition of both adult spe- 

 cimens, and found all the teeth of equal length. Coluber getidus 

 is often confounded with a variety of Coronella sayi exhibiting 

 irregular cross-bands. Should the difi'erence in the dentition 

 prove to be such as I found on examination, this would be the 

 most important character to avoid further mistake.
