290 SNAKES OF THE PHILIPPINE ISLANDS 



following scale variations: Ventrals, 170 to 187, average, 179; 

 subcaudals, 55 to 73, average, 62. The larger proportion of spec- 

 imens I have examined (five out of nine) have 2 labials touching 

 subocular; upper labials vary between 9 and 11, 10 being the 

 usual number; lower labials, 10 to 13, 11 being the usual num- 

 ber; 9 or 10 rows of scales between supraoculars, 10 predominat- 

 ing.' The scale rows are invariably 21 (neck 25.) The color 

 and markings vary considerably ; usually a bright or ohve green 

 in life (bluish in alcohol), either uniform or with numerous 

 brown spots or blotches; the skin between the scales bro-woiish 

 or blackish; the broken line of yellow dots on the outer scale 

 rows is very characteristic of this species, and is present in all 

 specimens examined. 



Reviarks. — This species is found only in the Philippines, ap- 

 parently. Specimens have been reported from Luzon, Mindanao, 

 and Batan Island,* north of Luzon. Two specimens in the Santo 

 Tomas Museum are labeled Bohol and Jolo, respectively.
