and across the last supralabial to the side of neck and from there 

 to near the tip of the tail on the middle line of the outer scale 

 row, the lower edge of which is somewhat darker than the rest 

 of the body; underside paler green, washed with blue so as to 

 be almost 'beryl-green' toward the sides ; tips of tail colored 

 like the rest of the body.

"The female appears to have a relatively much shorter tail." 

 Variation. — This widely distributed species is quite variable 

 in scalation and color. According to Boulenger,* the ventral 

 range is 145 to 175, average, 162.5 ; subcaudal, 53 to 75, average, 

 60. Rarely there are 19 or 23 rows. The scales between oculars 

 vary between 8 and 13; the nasal is sometimes divided; the tem- 

 poral scales are smooth. Bright green, rarely olive or yellowish, 

 with or without crossbands ; the yellow streak is usually present. 

 Remarks. — Known from India to Formosa, Siam, Sumatra, 

 Java, Timor, and Borneo. In the Philippines it has been re- 

 ported from Paracale, Luzon, by Peters, as Bothrops viridis; 

 from southern Mindanao by Fischer; and from Palawan by 

 Griffin. t I regard it of rather doubtful occurrence in the Phil- 

 ippines.
