are slightly wider than in R. luzonensis. The color and mark- 
ings are strikingly different. 
Specimens of this species were collected only at Balbalan, 
Kalinga, on the edge of a small brook. When disturbed they 
dived in the brook and hid under rocks at the bottom, where 
they were captured. 
The name of the species is derived from Igorot, the generic 
name applied to the —* inhabiting the central part of north- 
ern Luzon.
