along the ventral sides is here very distinctly developed , 

 and also the black edgings on the scales of the last series. 



Eight of these specimens were captured in Sumatra , one 

 in the island of Banka. 



In connection with the green color of the young B. 

 Wagleri, I suppose the now described nine green pitvipers 

 to be young specimens of B. sumatramts. If later researches 

 might prove this supposition to be false , I propose the 

 name of Bothrops Hageni for the green , red-tailed 

 Bothrops, with 180 — 190 ventral shields.
