SNAKES OF THE PHILIPPINE ISLANDS 



15 ventrals less for the males, and 8 ventrals less for the females, 

 while the number of subcaudals in the Mindanao foi'ms is higher 

 in both cases. The range of ventrals for the species is 128 to 

 157 ; of subcaudals, 37 to 59. The temporal scales in the Min- 

 danao specimens are normally 1 + 2. Of thirty-one specimens 

 examined twenty-four had the normal arrangement ; five had the 

 number on one side only, and two had 2 + 2, which is the normal 

 formula in the northern specimens. The loreal in northern 

 forms is constantly larger, as is the superior preocular which ex- 

 tends well above the loreal ; the number of lower labials touching 

 the anterior chin shields averages one less in Mindanao speci- 

 mens. The same variations of color are found in both groups. 

 The color in young specimens varies considerably from that 

 in the adult. The median dark stripe is distinct, going forward 

 to between the eyes where the interorbital bar intersects it; 

 another bar of dark brown crosses it in the occipital region ; on
