above nasals largest; nasal longer than high, nostril pierced near 

 center, and a small fold or semisuture to edge of scale above 

 nostril ; pit surrounded by second labial and 2 of the 3 preoculars ; 

 the 3 preoculars longer than high, the upper largest, all 

 entering eye; supraoculars elongate, irregular on their inner 

 side; 2 small postoculars and a long narrow subocular touching 

 lowest preocular; scales in temporal region much larger than 

 those on top of head; 10 upper labials (11 on right side), third 

 in contact with subocular; a scale inserted between subocular 

 and fourth labial; 2 scales between subocular and fifth labial; 

 13 lower labials, 3 touching chin shields which are elongate ; 

 these chin shields are followed by 4 paired scales; scales in 21 

 rows about body; median scales strongly keeled, outer slightly; 

 anterior head scales smooth, enlarged ; ventrals, 198, subcaudals, 

 66; tail prehensile; scales on head small, rounding, irregular, 

 subimbricate, not keeled. 



Color in alcohol. — Above, dark purplish brown with about 62 

 black, irregular, dim bars crossing back; top of head strongly 

 reticulated with black lines; outer row of scales bright yellow; 

 underpart of head muddy yellow with a darker spot under each 

 jaw and darker areas on labials ; a j'ellow line from eye to angle

mm. 



Total length 1,220 



Snout to vent 1,022 



Tail 198 



Variation. — The young are bright yellowish to bluish geen, 

 also barred with black ; belly scales indistinctly edged with black ; 

 reticulations on head very distinct, sometimes forming a flower- 

 shaped marking on occiput. In a specimen,* 576 millimeters 

 long, the color is brown. The outer row of scales is here spotted 

 with a light purplish color. 



Remarks. — I have taken an adult specimen for the description 

 rather than the type which is at hand, since the latter is a very 

 small, immature specimen. 



* This specimen is recorded in the catalogue of the Bureau of Science 

 collection as T. gramineus. Doctor Griffin reports it as the first occurrence 

 of this species in the Philippines. I believe that it should be regarded 

 as T. schultzei, as the two species differ in no essential particular. See 

 Philip. Journ. Sci. § A 4 (1909) 600.
