A careful comparison of specimens from both north and south of 

 the type locality of grilli, described by Boulenger (1913) from 

 Parana, Brazil, indicates that it is probably merely a variation of 

 the present species. The most remarkable character attributed to 

 grilli, the contact of the azygous prefrontal with the second supra- 

 ocular, is shown by none of the specimens listed below, although the 

 approach of these two plates is more pronounced in some examples 

 than in others.
