While the number of specimens examined is considerable, those which have the 

 sex determined are relativey few; consequently the measiu-ements do not make a 

 satisfactory showing as to geographic variations in this respect. As to coloration, 

 specimens from the States of Vera Cruz and Tabasco, Mexico, are appreciably darker 

 or less yellowish green above than most examples from Guatemala, British Honduras, 

 and Honduras, but the difference seems to be too slight and too inconstant to justify 

 further subdivision.
