TRIMERESURUS WAGLERI WAGLERI (Boie) 



Plate 37, fig. 4 

 Copiiias ivagleri Boie, Isis (1827) 561. 



It is highly probable that all references to Trimeresurus ivag- 

 leri (Boie) as occurring in Palawan should be referred to this 

 subspecies. 



There is no necessity of a complete description of this sub- 

 species; the following characteristics will enable one to dis- 

 tinguish the form. 



Ventrals, 139 ; subcaudals, 51 ; scales between the supraoculars, 

 12 ; bars across body, 45 (these counts are the averages of fifteen 

 specimens from Palawan and Balabac.) The scale rows vary 

 between 21 and 25. 



The coloration is usually bluish green barred above with 

 narrow stripes of white and dark blue, 2 scales wide. Ventrals 

 edged with black and with rather large spots of bluish or black; 

 a white and blue bar behind eye. Tail brownish red. 



In young specimens the entire color above is green, or green 

 with a very few white and blue spots. Occasional spechnens 

 show bars of white and brownish. 



The species agrees in size and general color with the sub- 

 species T. wagleri subauuulatns Gray. It is not a rare snake 

 m either Palawan or Balabac. It probablv does not occur 

 anywhere ni the Philippines save in the Palawan group and the 

 Calamianes.
