three to five small scale rows in interorbital space; nine 

 to eleven upper labials, last usually much elong'ate; nine to 

 eleven lower labials; a row of suboculars below latter half

 four rows of scales ; a row of three or four large, prominent 

 scales back of eye ; tympanum covered with several scales larger 

 than the surrounding ones; body with rather large keeled 

 scales on back with a series of distant large scales forming 

 indistinct lines on either side, separated from each other by 

 twenty-two to twenty-four rows of scales, and on neck forming 

 slight, continuous, lateral crests; a dorsal nuchal crest rather 

 prominent ; two or three scattered prominent scales back of tem- 

 poral region ; gular appendage one and one-half times length of 

 head; foreleg brought forward reaches much beyond snout; 

 hind leg contained in axilla-to-groin distance about one and one- 

 tenth times ; lateral nuchal appendages rather small. 



Color in life. — Greenish gray above with metallic reflections, 

 slightly iridescent, with small brownish spots on sides of body

Variation. — (Male.) In the collection of the Santo Tomas 

 University there are several male specimens of this species. 

 With one exception they agree fairly well with the specimens 

 here recorded. In none however is the series of enlarged 

 scales on snout arranged in a Y-shaped formation. All agree
