The present material is too poorly distributed to show anything 

 about variation in caudals or tail length, since the numbers for aver- 

 ages are too much reduced by the necessity of treating the sexes 

 separately.

The number of yellow annuli of the color pattern is so variable that 

 little can be said beyond calling attention to the fact that the averages 

 for a few localities vary in the same sense as the averages for the 

 ventrals — Vera Cruz, 25; Guatemala, 31; Nicaragua, 24; Costa Rica, 

 26; Panama to Ecuador, 18.
